text: Embroidery is a long-standing and high-quality approach to making logos and
images on textiles. Nowadays, it can also be performed via automated machines
that weave threads with high spatial accuracy. A characteristic feature of the
appearance of the threads is a high degree of anisotropy. The anisotropic behavior
is caused by depositing thin but long strings of thread. As a result, the stitched
patterns convey both color and direction. Artists leverage this anisotropic behavior
to enhance pure color images with textures, illusions of motion, or depth cues.
However, designing colorful embroidery patterns with prescribed directionality
is a challenging task, one usually requiring an expert designer. In this work,
we propose an interactive algorithm that generates machine-fabricable embroidery
patterns from multi-chromatic images equipped with user-specified directionality
fields.We cast the problem of finding a stitching pattern into vector theory.
To find a suitable stitching pattern, we extract sources and sinks from the divergence
field of the vector field extracted from the input and use them to trace streamlines.
We further optimize the streamlines to guarantee a smooth and connected stitching
pattern. The generated patterns approximate the color distribution constrained
by the directionality field. To allow for further artistic control, the trade-off
between color match and directionality match can be interactively explored via
an intuitive slider. We showcase our approach by fabricating several embroidery
paths.

text: We present a technique to optimize the reflectivity of a surface while preserving
its overall shape. The naïve optimization of the mesh vertices using the gradients
of reflectivity simulations results in undesirable distortion. In contrast, our
robust formulation optimizes the surface normal as an independent variable that
bridges the reflectivity term with differential rendering, and the regularization
term with as-rigid-as-possible elastic energy. We further adaptively subdivide
the input mesh to improve the convergence. Consequently, our method can minimize
the retroreflectivity of a wide range of input shapes, resulting in sharply creased
shapes ubiquitous among stealth aircraft and Sci-Fi vehicles. Furthermore, by
changing the reward for the direction of the outgoing light directions, our method
can be applied to other reflectivity design tasks, such as the optimization of
architectural walls to concentrate light in a specific region. We have tested
the proposed method using light-transport simulations and real-world 3D-printed
objects.

text: 'Portrait viewpoint and illumination editing is an important problem with
several applications in VR/AR, movies, and photography. Comprehensive knowledge
of geometry and illumination is critical for obtaining photorealistic results.
Current methods are unable to explicitly model in 3D while handling both viewpoint
and illumination editing from a single image. In this paper, we propose VoRF,
a novel approach that can take even a single portrait image as input and relight
human heads under novel illuminations that can be viewed from arbitrary viewpoints.
VoRF represents a human head as a continuous volumetric field and learns a prior
model of human heads using a coordinate-based MLP with individual latent spaces
for identity and illumination. The prior model is learned in an auto-decoder manner
over a diverse class of head shapes and appearances, allowing VoRF to generalize
to novel test identities from a single input image. Additionally, VoRF has a reflectance
MLP that uses the intermediate features of the prior model for rendering One-Light-at-A-Time
(OLAT) images under novel views. We synthesize novel illuminations by combining
these OLAT images with target environment maps. Qualitative and quantitative evaluations
demonstrate the effectiveness of VoRF for relighting and novel view synthesis,
even when applied to unseen subjects under uncontrolled illumination. This work
is an extension of Rao et al. (VoRF: Volumetric Relightable Faces 2022). We provide
extensive evaluation and ablative studies of our model and also provide an application,
where any face can be relighted using textual input.'

text: We introduce a compact, intuitive procedural graph representation for cellular
metamaterials, which are small-scale, tileable structures that can be architected
to exhibit many useful material properties. Because the structures’ “architectures”
vary widely—with elements such as beams, thin shells, and solid bulks—it is difficult
to explore them using existing representations. Generic approaches like voxel
grids are versatile, but it is cumbersome to represent and edit individual structures;
architecture-specific approaches address these issues, but are incompatible with
one another. By contrast, our procedural graph succinctly represents the construction
process for any structure using a simple skeleton annotated with spatially varying
thickness. To express the highly constrained triply periodic minimal surfaces
(TPMS) in this manner, we present the first fully automated version of the conjugate
surface construction method, which allows novices to create complex TPMS from
intuitive input. We demonstrate our representation’s expressiveness, accuracy,
and compactness by constructing a wide range of established structures and hundreds
of novel structures with diverse architectures and material properties. We also
conduct a user study to verify our representation’s ease-of-use and ability to
expand engineers’ capacity for exploration.

with a wide range of materials. An important shortcoming of this type of technology
is its limited multi-material capabilities. While there are simple hardware designs
that enable multi-material printing in principle, the required software is heavily
underdeveloped. A typical hardware design fuses together individual materials
fed into a single chamber from multiple inlets before they are deposited. This
design, however, introduces a time delay between the intended material mixture
and its actual deposition. In this work, inspired by diverse path planning research
in robotics, we show that this mechanical challenge can be addressed via improved
printer control. We propose to formulate the search for optimal multi-material
printing policies in a reinforcement\r\nlearning setup. We put forward a simple
numerical deposition model that takes into account the non-linear material mixing
and delayed material deposition. To validate our system we focus on color fabrication,
a problem known for its strict requirements for varying material mixtures at a
high spatial frequency. We demonstrate that our learned control policy outperforms
state-of-the-art hand-crafted algorithms."

text: In this study, we propose a computational framework for optimizing the continuity
of the toolpath in fabricating surface models on an extrusion-based 3D printer.
Toolpath continuity is a critical issue that influences both the quality and the
efficiency of extrusion-based fabrication. Transfer moves lead to rough and bumpy
surfaces, where this phenomenon worsens for materials with large viscosity, like
clay. The effects of continuity on the surface models are even more severe in
terms of the quality of the surface and the stability of the model. We introduce
a criterion called the one–path patch (OPP) to represent a patch on the surface
of the shell that can be traversed along one path by considering the constraints
on fabrication. We study the properties of the OPPs and their merging operations
to propose a bottom-up OPP merging procedure to decompose the given shell surface
into a minimal number of OPPs, and to generate the “as-continuous-as-possible”
(ACAP) toolpath. Furthermore, we augment the path planning algorithm with a curved-layer
printing scheme that reduces staircase defects and improves the continuity of
the toolpath by connecting multiple segments. We evaluated the ACAP algorithm
on ceramic and thermoplastic materials, and the results showed that it improves
the fabrication of surface models in terms of both efficiency and surface quality.

text: Three-dimensional (3D) reconstruction of living brain tissue down to an individual
synapse level would create opportunities for decoding the dynamics and structure–function
relationships of the brain’s complex and dense information processing network;
however, this has been hindered by insufficient 3D resolution, inadequate signal-to-noise
ratio and prohibitive light burden in optical imaging, whereas electron microscopy
is inherently static. Here we solved these challenges by developing an integrated
optical/machine-learning technology, LIONESS (live information-optimized nanoscopy
enabling saturated segmentation). This leverages optical modifications to stimulated
emission depletion microscopy in comprehensively, extracellularly labeled tissue
and previous information on sample structure via machine learning to simultaneously
achieve isotropic super-resolution, high signal-to-noise ratio and compatibility
with living tissue. This allows dense deep-learning-based instance segmentation
and 3D reconstruction at a synapse level, incorporating molecular, activity and
morphodynamic information. LIONESS opens up avenues for studying the dynamic functional
(nano-)architecture of living brain tissue.

text: 'A faithful reproduction of gloss is inherently difficult because of the limited
dynamic range, peak luminance, and 3D capabilities of display devices. This work
investigates how the display capabilities affect gloss appearance with respect
to a real-world reference object. To this end, we employ an accurate imaging pipeline
to achieve a perceptual gloss match between a virtual and real object presented
side-by-side on an augmented-reality high-dynamic-range (HDR) stereoscopic display,
which has not been previously attained to this extent. Based on this precise gloss
reproduction, we conduct a series of gloss matching experiments to study how gloss
perception degrades based on individual factors: object albedo, display luminance,
dynamic range, stereopsis, and tone mapping. We support the study with a detailed
analysis of individual factors, followed by an in-depth discussion on the observed
perceptual effects. Our experiments demonstrate that stereoscopic presentation
has a limited effect on the gloss matching task on our HDR display. However, both
reduced luminance and dynamic range of the display reduce the perceived gloss.
This means that the visual system cannot compensate for the changes in gloss appearance
across luminance (lack of gloss constancy), and the tone mapping operator should
be carefully selected when reproducing gloss on a low dynamic range (LDR) display.'

text: "We propose a computational design approach for covering a surface with individually
addressable RGB LEDs, effectively forming a low-resolution surface screen. To
achieve a low-cost and scalable approach, we propose creating designs from flat
PCB panels bent in-place along the surface of a 3D printed core. Working with
standard rigid PCBs enables the use of\r\nestablished PCB manufacturing services,
allowing the fabrication of designs with several hundred LEDs. \r\nOur approach
optimizes the PCB geometry for folding, and then jointly optimizes the LED packing,
circuit and routing, solving a challenging layout problem under strict manufacturing
requirements. Unlike paper, PCBs cannot bend beyond a certain point without breaking.
Therefore, we introduce parametric cut patterns acting as hinges, designed to
allow bending while remaining compact. To tackle the joint optimization of placement,
circuit and routing, we propose a specialized algorithm that splits the global
problem into one sub-problem per triangle, which is then individually solved.\r\nOur
technique generates PCB blueprints in a completely automated way. After being
fabricated by a PCB manufacturing service, the boards are bent and glued by the
user onto the 3D printed support. We demonstrate our technique on a range of physical
models and virtual examples, creating intricate surface light patterns from hundreds
of LEDs."

text: Tattoos are a highly popular medium, with both artistic and medical applications.
Although the mechanical process of tattoo application has evolved historically,
the results are reliant on the artisanal skill of the artist. This can be especially
challenging for some skin tones, or in cases where artists lack experience. We
provide the first systematic overview of tattooing as a computational fabrication
technique. We built an automated tattooing rig and a recipe for the creation of
silicone sheets mimicking realistic skin tones, which allowed us to create an
accurate model predicting tattoo appearance. This enables several exciting applications
including tattoo previewing, color retargeting, novel ink spectra optimization,
color-accurate prosthetics, and more.

text: 'Color and gloss are fundamental aspects of surface appearance. State-of-the-art
fabrication techniques can manipulate both properties of the printed 3D objects.
However, in the context of appearance reproduction, perceptual aspects of color
and gloss are usually handled separately, even though previous perceptual studies
suggest their interaction. Our work is motivated by previous studies demonstrating
a perceived color shift due to a change in the object''s gloss, i.e., two samples
with the same color but different surface gloss appear as they have different
colors. In this paper, we conduct new experiments which support this observation
and provide insights into the magnitude and direction of the perceived color change.
We use the observations as guidance to design a new method that estimates and
corrects the color shift enabling the fabrication of objects with the same perceived
color but different surface gloss. We formulate the problem as an optimization
procedure solved using differentiable rendering. We evaluate the effectiveness
of our method in perceptual experiments with 3D objects fabricated using a multi-material
3D printer and demonstrate potential applications. '

solved on discrete representations such as polygonal meshes. This thesis argues
that there are benefits to treating these problems in the same domain as human
designers, namely, the parametric one. One reason is that discretizing a parametric
model usually removes the capability of making further manual changes to the design,
because the human intent is captured by the shape parameters. Beyond this, knowledge
about a design problem can sometimes reveal a structure that is present in a smooth
representation, but is fundamentally altered by discretizing. In this case, working
in the parametric domain may even simplify the optimization task. We present two
lines of research that explore both of these aspects of fabrication-aware shape
optimization on parametric representations.\r\n\r\nThe first project studies the
design of plane elastic curves and Kirchhoff rods, which are common mathematical
models for describing the deformation of thin elastic rods such as beams, ribbons,
cables, and hair. Our main contribution is a characterization of all curved shapes
that can be attained by bending and twisting elastic rods having a stiffness that
is allowed to vary across the length. Elements like these can be manufactured
using digital fabrication devices such as 3d printers and digital cutters, and
have applications in free-form architecture and soft robotics.\r\n\r\nWe show
that the family of curved shapes that can be produced this way admits geometric
description that is concise and computationally convenient. In the case of plane
curves, the geometric description is intuitive enough to allow a designer to determine
whether a curved shape is physically achievable by visual inspection alone. We
also present shape optimization algorithms that convert a user-defined curve in
the plane or in three dimensions into the geometry of an elastic rod that will
naturally deform to follow this curve when its endpoints are attached to a support
structure. Implemented in an interactive software design tool, the rod geometry
is generated in real time as the user edits a curve and enables fast prototyping.
\r\n\r\nThe second project tackles the problem of general-purpose shape optimization
on CAD models using a novel variant of the extended finite element method (XFEM).
Our goal is the decoupling between the simulation mesh and the CAD model, so no
geometry-dependent meshing or remeshing needs to be performed when the CAD parameters
change during optimization. This is achieved by discretizing the embedding space
of the CAD model, and using a new high-accuracy numerical integration method to
enable XFEM on free-form elements bounded by the parametric surface patches of
the model. Our simulation is differentiable from the CAD parameters to the simulation
output, which enables us to use off-the-shelf gradient-based optimization procedures.
The result is a method that fits seamlessly into the CAD workflow because it works
on the same representation as the designer, enabling the alternation of manual
editing and fabrication-aware optimization at will."

text: "The Kirchhoff rod model describes the bending and twisting of slender elastic
rods in three dimensions, and has been widely studied to enable the prediction
of how a rod will deform, given its geometry and boundary conditions. In this
work, we study a number of inverse problems with the goal of computing the geometry
of a straight rod that will automatically deform to match a curved target shape
after attaching its endpoints to a support structure. Our solution lets us finely
control the static equilibrium state of a rod by varying the cross-sectional profiles
along its length.\r\nWe also show that the set of physically realizable equilibrium
states admits a concise geometric description in terms of linear line complexes,
which leads to very efficient computational design algorithms. Implemented in
an interactive software tool, they allow us to convert three-dimensional hand-drawn
spline curves to elastic rods, and give feedback about the feasibility and practicality
of a design in real time. We demonstrate the efficacy of our method by designing
and manufacturing several physical prototypes with applications to interior design
and soft robotics."

text: A good match of material appearance between real-world objects and their digital
on-screen representations is critical for many applications such as fabrication,
design, and e-commerce. However, faithful appearance reproduction is challenging,
especially for complex phenomena, such as gloss. In most cases, the view-dependent
nature of gloss and the range of luminance values required for reproducing glossy
materials exceeds the current capabilities of display devices. As a result, appearance
reproduction poses significant problems even with accurately rendered images.
This paper studies the gap between the gloss perceived from real-world objects
and their digital counterparts. Based on our psychophysical experiments on a wide
range of 3D printed samples and their corresponding photographs, we derive insights
on the influence of geometry, illumination, and the display’s brightness and measure
the change in gloss appearance due to the display limitations. Our evaluation
experiments demonstrate that using the prediction to correct material parameters
in a rendering system improves the match of gloss appearance between real objects
and their visualization on a display device.

text: "Enabling additive manufacturing to employ a wide range of novel, functional
materials can be a major boost to this technology. However, making such materials
printable requires painstaking trial-and-error by an expert operator,\r\nas they
typically tend to exhibit peculiar rheological or hysteresis properties. Even
in the case of successfully finding the process parameters, there is no guarantee
of print-to-print consistency due to material differences between batches. These
challenges make closed-loop feedback an attractive option where the process parameters
are adjusted on-the-fly. There are several challenges for designing an efficient
controller: the deposition parameters are complex and highly coupled, artifacts
occur after long time horizons, simulating the deposition is computationally costly,
and learning on hardware is intractable. In this work, we demonstrate the feasibility
of learning a closed-loop control policy for additive manufacturing using reinforcement
learning. We show that approximate, but efficient, numerical simulation is\r\nsufficient
as long as it allows learning the behavioral patterns of deposition that translate
to real-world experiences. In combination with reinforcement learning, our model
can be used to discover control policies that outperform\r\nbaseline controllers.
Furthermore, the recovered policies have a minimal sim-to-real gap. We showcase
this by applying our control policy in-vivo on a single-layer, direct ink writing
printer. "

text: We study structural rigidity for assemblies with mechanical joints. Existing
methods identify whether an assembly is structurally rigid by assuming parts are
perfectly rigid. Yet, an assembly identified as rigid may not be that “rigid”
in practice, and existing methods cannot quantify how rigid an assembly is. We
address this limitation by developing a new measure, worst-case rigidity, to quantify
the rigidity of an assembly as the largest possible deformation that the assembly
undergoes for arbitrary external loads of fixed magnitude. Computing worst-case
rigidity is non-trivial due to non-rigid parts and different joint types. We thus
formulate a new computational approach by encoding parts and their connections
into a stiffness matrix, in which parts are modeled as deformable objects and
joints as soft constraints. Based on this, we formulate worst-case rigidity analysis
as an optimization that seeks the worst-case deformation of an assembly for arbitrary
external loads, and solve the optimization problem via an eigenanalysis. Furthermore,
we present methods to optimize the geometry and topology of various assemblies
to enhance their rigidity, as guided by our rigidity measure. In the end, we validate
our method on a variety of assembly structures with physical experiments and demonstrate
its effectiveness by designing and fabricating several structurally rigid assemblies.

text: "Interlocking puzzles are intriguing geometric games where the puzzle pieces
are held together based on their geometric arrangement, preventing the puzzle
from falling apart. High-level-of-difficulty, or simply high-level, interlocking
puzzles are a subclass of interlocking puzzles that require multiple moves to
take out the first subassembly from the puzzle. Solving a high-level interlocking
puzzle is a challenging task since one has to explore many different configurations
of the puzzle pieces until reaching a configuration where the first subassembly
can be taken out. Designing a high-level interlocking puzzle with a user-specified
level of difficulty is even harder since the puzzle pieces have to be interlocking
in all the configurations before the first subassembly is taken out.\r\n\r\nIn
this paper, we present a computational approach to design high-level interlocking
puzzles. The core idea is to represent all possible configurations of an interlocking
puzzle as well as transitions among these configurations using a rooted, undirected
graph called a disassembly graph and leverage this graph to find a disassembly
plan that requires a minimal number of moves to take out the first subassembly
from the puzzle. At the design stage, our algorithm iteratively constructs the
geometry of each puzzle piece to expand the disassembly graph incrementally, aiming
to achieve a user-specified level of difficulty. We show that our approach allows
efficient generation of high-level interlocking puzzles of various shape complexities,
including new solutions not attainable by state-of-the-art approaches."

text: Moulding refers to a set of manufacturing techniques in which a mould, usually
a cavity or a solid frame, is used to shape a liquid or pliable material into
an object of the desired shape. The popularity of moulding comes from its effectiveness,
scalability and versatility in terms of employed materials. Its relevance as a
fabrication process is demonstrated by the extensive literature covering different
aspects related to mould design, from material flow simulation to the automation
of mould geometry design. In this state-of-the-art report, we provide an extensive
review of the automatic methods for the design of moulds, focusing on contributions
from a geometric perspective. We classify existing mould design methods based
on their computational approach and the nature of their target moulding process.
We summarize the relationships between computational approaches and moulding techniques,
highlighting their strengths and limitations. Finally, we discuss potential future
research directions.

text: Portrait viewpoint and illumination editing is an important problem with several
applications in VR/AR, movies, and photography. Comprehensive knowledge of geometry
and illumination is critical for obtaining photorealistic results. Current methods
are unable to explicitly model in 3D while handing both viewpoint and illumination
editing from a single image. In this paper, we propose VoRF, a novel approach
that can take even a single portrait image as input and relight human heads under
novel illuminations that can be viewed from arbitrary viewpoints. VoRF represents
a human head as a continuous volumetric field and learns a prior model of human
heads using a coordinate-based MLP with separate latent spaces for identity and
illumination. The prior model is learnt in an auto-decoder manner over a diverse
class of head shapes and appearances, allowing VoRF to generalize to novel test
identities from a single input image. Additionally, VoRF has a reflectance MLP
that uses the intermediate features of the prior model for rendering One-Light-at-A-Time
(OLAT) images under novel views. We synthesize novel illuminations by combining
these OLAT images with target environment maps. Qualitative and quantitative evaluations
demonstrate the effectiveness of VoRF for relighting and novel view synthesis
even when applied to unseen subjects under uncontrolled illuminations.

text: Complex wiring between neurons underlies the information-processing network
enabling all brain functions, including cognition and memory. For understanding
how the network is structured, processes information, and changes over time, comprehensive
visualization of the architecture of living brain tissue with its cellular and
molecular components would open up major opportunities. However, electron microscopy
(EM) provides nanometre-scale resolution required for full in-silico
reconstruction1–5, yet is limited to fixed specimens and
static representations. Light microscopy allows live observation, with super-resolution
approaches6–12 facilitating nanoscale visualization, but
comprehensive 3D-reconstruction of living brain tissue has been hindered by tissue
photo-burden, photobleaching, insufficient 3D-resolution, and inadequate signal-to-noise
ratio (SNR). Here we demonstrate saturated reconstruction of living brain tissue.
We developed an integrated imaging and analysis technology, adapting stimulated
emission depletion (STED) microscopy6,13 in extracellularly
labelled tissue14 for high SNR and near-isotropic resolution.
Centrally, a two-stage deep-learning approach leveraged previously obtained information
on sample structure to drastically reduce photo-burden and enable automated volumetric
reconstruction down to single synapse level. Live reconstruction provides unbiased
analysis of tissue architecture across time in relation to functional activity
and targeted activation, and contextual understanding of molecular labelling.
This adoptable technology will facilitate novel insights into the dynamic functional
architecture of living brain tissue.

text: Tactile feedback of an object’s surface enables us to discern its material
properties and affordances. This understanding is used in digital fabrication
processes by creating objects with high-resolution surface variations to influence
a user’s tactile perception. As the design of such surface haptics commonly relies
on knowledge from real-life experiences, it is unclear how to adapt this information
for digital design methods. In this work, we investigate replicating the haptics
of real materials. Using an existing process for capturing an object’s microgeometry,
we digitize and reproduce the stable surface information of a set of 15 fabric
samples. In a psychophysical experiment, we evaluate the tactile qualities of
our set of original samples and their replicas. From our results, we see that
direct reproduction of surface variations is able to influence different psychophysical
dimensions of the tactile perception of surface textures. While the fabrication
process did not preserve all properties, our approach underlines that replication
of surface microgeometries benefits fabrication methods in terms of haptic perception
by covering a large range of tactile variations. Moreover, by changing the surface
structure of a single fabricated material, its material perception can be influenced.
We conclude by proposing strategies for capturing and reproducing digitized textures
to better resemble the perceived haptics of the originals.

text: 'Volumetric light transport is a pervasive physical phenomenon, and therefore
its accurate simulation is important for a broad array of disciplines. While suitable
mathematical models for computing the transport are now available, obtaining the
necessary material parameters needed to drive such simulations is a challenging
task: direct measurements of these parameters from material samples are seldom
possible. Building on the inverse scattering paradigm, we present a novel measurement
approach which indirectly infers the transport parameters from extrinsic observations
of multiple-scattered radiance. The novelty of the proposed approach lies in replacing
structured illumination with a structured reflector bonded to the sample, and
a robust fitting procedure that largely compensates for potential systematic errors
in the calibration of the setup. We show the feasibility of our approach by validating
simulations of complex 3D compositions of the measured materials against physical
prints, using photo-polymer resins. As presented in this paper, our technique
yields colorspace data suitable for accurate appearance reproduction in the area
of 3D printing. Beyond that, and without fundamental changes to the basic measurement
methodology, it could equally well be used to obtain spectral measurements that
are useful for other application areas.'

text: This paper presents a method for designing planar multistable compliant structures.
Given a sequence of desired stable states and the corresponding poses of the structure,
we identify the topology and geometric realization of a mechanism—consisting of
bars and joints—that is able to physically reproduce the desired multistable behavior.
In order to solve this problem efficiently, we build on insights from minimally
rigid graph theory to identify simple but effective topologies for the mechanism.
We then optimize its geometric parameters, such as joint positions and bar lengths,
to obtain correct transitions between the given poses. Simultaneously, we ensure
adequate stability of each pose based on an effective approximate error metric
related to the elastic energy Hessian of the bars in the mechanism. As demonstrated
by our results, we obtain functional multistable mechanisms of manageable complexity
that can be fabricated using 3D printing. Further, we evaluated the effectiveness
of our method on a large number of examples in the simulation and fabricated several
physical prototypes.

text: We present a computational design system that assists users to model, optimize,
and fabricate quad-robots with soft skins. Our system addresses the challenging
task of predicting their physical behavior by fully integrating the multibody
dynamics of the mechanical skeleton and the elastic behavior of the soft skin.
The developed motion control strategy uses an alternating optimization scheme
to avoid expensive full space time-optimization, interleaving space-time optimization
for the skeleton, and frame-by-frame optimization for the full dynamics. The output
are motor torques to drive the robot to achieve a user prescribed motion trajectory.
We also provide a collection of convenient engineering tools and empirical manufacturing
guidance to support the fabrication of the designed quad-robot. We validate the
feasibility of designs generated with our system through physics simulations and
with a physically-fabricated prototype.

text: Photorealistic editing of head portraits is a challenging task as humans are
very sensitive to inconsistencies in faces. We present an approach for high-quality
intuitive editing of the camera viewpoint and scene illumination (parameterised
with an environment map) in a portrait image. This requires our method to capture
and control the full reflectance field of the person in the image. Most editing
approaches rely on supervised learning using training data captured with setups
such as light and camera stages. Such datasets are expensive to acquire, not readily
available and do not capture all the rich variations of in-the-wild portrait images.
In addition, most supervised approaches only focus on relighting, and do not allow
camera viewpoint editing. Thus, they only capture and control a subset of the
reflectance field. Recently, portrait editing has been demonstrated by operating
in the generative model space of StyleGAN. While such approaches do not require
direct supervision, there is a significant loss of quality when compared to the
supervised approaches. In this paper, we present a method which learns from limited
supervised training data. The training images only include people in a fixed neutral
expression with eyes closed, without much hair or background variations. Each
person is captured under 150 one-light-at-a-time conditions and under 8 camera
poses. Instead of training directly in the image space, we design a supervised
problem which learns transformations in the latent space of StyleGAN. This combines
the best of supervised learning and generative adversarial modeling. We show that
the StyleGAN prior allows for generalisation to different expressions, hairstyles
and backgrounds. This produces high-quality photorealistic results for in-the-wild
images and significantly outperforms existing methods. Our approach can edit the
illumination and pose simultaneously, and runs at interactive rates.

text: Material appearance hinges on material reflectance properties but also surface
geometry and illumination. The unlimited number of potential combinations between
these factors makes understanding and predicting material appearance a very challenging
task. In this work, we collect a large-scale dataset of perceptual ratings of
appearance attributes with more than 215,680 responses for 42,120 distinct combinations
of material, shape, and illumination. The goal of this dataset is twofold. First,
we analyze for the first time the effects of illumination and geometry in material
perception across such a large collection of varied appearances. We connect our
findings to those of the literature, discussing how previous knowledge generalizes
across very diverse materials, shapes, and illuminations. Second, we use the collected
dataset to train a deep learning architecture for predicting perceptual attributes
that correlate with human judgments. We demonstrate the consistent and robust
behavior of our predictor in various challenging scenarios, which, for the first
time, enables estimating perceived material attributes from general 2D images.
Since our predictor relies on the final appearance in an image, it can compare
appearance properties across different geometries and illumination conditions.
Finally, we demonstrate several applications that use our predictor, including
appearance reproduction using 3D printing, BRDF editing by integrating our predictor
in a differentiable renderer, illumination design, or material recommendations
for scene design.

text: The reflectance field of a face describes the reflectance properties responsible
for complex lighting effects including diffuse, specular, inter-reflection and
self shadowing. Most existing methods for estimating the face reflectance from
a monocular image assume faces to be diffuse with very few approaches adding a
specular component. This still leaves out important perceptual aspects of reflectance
as higher-order global illumination effects and self-shadowing are not modeled.
We present a new neural representation for face reflectance where we can estimate
all components of the reflectance responsible for the final appearance from a
single monocular image. Instead of modeling each component of the reflectance
separately using parametric models, our neural representation allows us to generate
a basis set of faces in a geometric deformation-invariant space, parameterized
by the input light direction, viewpoint and face geometry. We learn to reconstruct
this reflectance field of a face just from a monocular image, which can be used
to render the face from any viewpoint in any light condition. Our method is trained
on a light-stage training dataset, which captures 300 people illuminated with
150 light conditions from 8 viewpoints. We show that our method outperforms existing
monocular reflectance reconstruction methods, in terms of photorealism due to
better capturing of physical premitives, such as sub-surface scattering, specularities,
self-shadows and other higher-order effects.

text: With the wider availability of full-color 3D printers, color-accurate 3D-print
preparation has received increased attention. A key challenge lies in the inherent
translucency of commonly used print materials that blurs out details of the color
texture. Previous work tries to compensate for these scattering effects through
strategic assignment of colored primary materials to printer voxels. To date,
the highest-quality approach uses iterative optimization that relies on computationally
expensive Monte Carlo light transport simulation to predict the surface appearance
from subsurface scattering within a given print material distribution; that optimization,
however, takes in the order of days on a single machine. In our work, we dramatically
speed up the process by replacing the light transport simulation with a data-driven
approach. Leveraging a deep neural network to predict the scattering within a
highly heterogeneous medium, our method performs around two orders of magnitude
faster than Monte Carlo rendering while yielding optimization results of similar
quality level. The network is based on an established method from atmospheric
cloud rendering, adapted to our domain and extended by a physically motivated
weight sharing scheme that substantially reduces the network size. We analyze
its performance in an end-to-end print preparation pipeline and compare quality
and runtime to alternative approaches, and demonstrate its generalization to unseen
geometry and material values. This for the first time enables full heterogenous
material optimization for 3D-print preparation within time frames in the order
of the actual printing time.

text: 'The understanding of material appearance perception is a complex problem
due to interactions between material reflectance, surface geometry, and illumination.
Recently, Serrano et al. collected the largest dataset to date with subjective
ratings of material appearance attributes, including glossiness, metallicness,
sharpness and contrast of reflections. In this work, we make use of their dataset
to investigate for the first time the impact of the interactions between illumination,
geometry, and eight different material categories in perceived appearance attributes.
After an initial analysis, we select for further analysis the four material categories
that cover the largest range for all perceptual attributes: fabric, plastic, ceramic,
and metal. Using a cumulative link mixed model (CLMM) for robust regression, we
discover interactions between these material categories and four representative
illuminations and object geometries. We believe that our findings contribute to
expanding the knowledge on material appearance perception and can be useful for
many applications, such as scene design, where any particular material in a given
shape can be aligned with dominant classes of illumination, so that a desired
strength of appearance attributes can be achieved.'

text: "We introduce a novel technique to automatically decompose an input object’s
volume into a set of parts that can be represented by two opposite height fields.
Such decomposition enables the manufacturing of individual parts using two-piece
reusable rigid molds. Our decomposition strategy relies on a new energy formulation
that utilizes a pre-computed signal on the mesh volume representing the accessibility
for a predefined set of extraction directions. Thanks to this novel formulation,
our method allows for efficient optimization of a fabrication-aware partitioning
of volumes in a completely\r\nautomatic way. We demonstrate the efficacy of our
approach by generating valid volume partitionings for a wide range of complex
objects and physically reproducing several of them."

text: Elastic bending of initially flat slender elements allows the realization
and economic fabrication of intriguing curved shapes. In this work, we derive
an intuitive but rigorous geometric characterization of the design space of plane
elastic rods with variable stiffness. It enables designers to determine which
shapes are physically viable with active bending by visual inspection alone. Building
on these insights, we propose a method for efficiently designing the geometry
of a flat elastic rod that realizes a target equilibrium curve, which only requires
solving a linear program. We implement this method in an interactive computational
design tool that gives feedback about the feasibility of a design, and computes
the geometry of the structural elements necessary to realize it within an instant.
The tool also offers an iterative optimization routine that improves the fabricability
of a model while modifying it as little as possible. In addition, we use our geometric
characterization to derive an algorithm for analyzing and recovering the stability
of elastic curves that would otherwise snap out of their unstable equilibrium
shapes by buckling. We show the efficacy of our approach by designing and manufacturing
several physical models that are assembled from flat elements.

text: 'Bending-active structures are able to efficiently produce complex curved
shapes from flat panels. The desired deformation of the panels derives from the
proper selection of their elastic properties. Optimized panels, called FlexMaps,
are designed such that, once they are bent and assembled, the resulting static
equilibrium configuration matches a desired input 3D shape. The FlexMaps elastic
properties are controlled by locally varying spiraling geometric mesostructures,
which are optimized in size and shape to match specific bending requests, namely
the global curvature of the target shape. The design pipeline starts from a quad
mesh representing the input 3D shape, which defines the edge size and the total
amount of spirals: every quad will embed one spiral. Then, an optimization algorithm
tunes the geometry of the spirals by using a simplified pre-computed rod model.
This rod model is derived from a non-linear regression algorithm which approximates
the non-linear behavior of solid FEM spiral models subject to hundreds of load
combinations. This innovative pipeline has been applied to the project of a lightweight
plywood pavilion named FlexMaps Pavilion, which is a single-layer piecewise twisted
arch that fits a bounding box of 3.90x3.96x3.25 meters. This case study serves
to test the applicability of this methodology at the architectural scale. The
structure is validated via FE analyses and the fabrication of the full scale prototype.'

text: BACKGROUND:The introduction of image-guided methods to bypass surgery has
resulted in optimized preoperative identification of the recipients and excellent
patency rates. However, the recently presented methods have also been resource-consuming.
In the present study, we have reported a cost-efficient planning workflow for
extracranial-intracranial (EC-IC) revascularization combined with transdural indocyanine
green videoangiography (tICG-VA). METHODS:We performed a retrospective review
at a single tertiary referral center from 2011 to 2018. A novel software-derived
workflow was applied for 25 of 92 bypass procedures during the study period. The
precision and accuracy were assessed using tICG-VA identification of the cortical
recipients and a comparison of the virtual and actual data. The data from a control
group of 25 traditionally planned procedures were also matched. RESULTS:The intraoperative
transfer time of the calculated coordinates averaged 0.8 minute (range, 0.4-1.9
minutes). The definitive recipients matched the targeted branches in 80%, and
a neighboring branch was used in 16%. Our workflow led to a significant craniotomy
size reduction in the study group compared with that in the control group (P =
0.005). tICG-VA was successfully applied in 19 cases. An average of 2 potential
recipient arteries were identified transdurally, resulting in tailored durotomy
and 3 craniotomy adjustments. Follow-up patency results were available for 49
bypass surgeries, comprising 54 grafts. The overall patency rate was 91% at a
median follow-up period of 26 months. No significant difference was found in the
patency rate between the study and control groups (P = 0.317). CONCLUSIONS:Our
clinical results have validated the presented planning and surgical workflow and
support the routine implementation of tICG-VA for recipient identification before
durotomy.

text: The combined resection of skull-infiltrating tumours and immediate cranioplastic
reconstruction predominantly relies on freehand-moulded solutions. Techniques
that enable this procedure to be performed easily in routine clinical practice
would be useful. A cadaveric study was developed in which a new software tool
was used to perform single-stage reconstructions with prefabricated implants after
the resection of skull-infiltrating pathologies. A novel 3D visualization and
interaction framework was developed to create 10 virtual craniotomies in five
cadaveric specimens. Polyether ether ketone (PEEK) implants were manufactured
according to the bone defects. The image-guided craniotomy was reconstructed with
PEEK and compared to polymethyl methacrylate (PMMA). Navigational accuracy and
surgical precision were assessed. The PEEK workflow resulted in up to 10-fold
shorter reconstruction times than the standard technique. Surgical precision was
reflected by the mean 1.1 ± 0.29 mm distance between the virtual and real craniotomy,
with submillimetre precision in 50%. Assessment of the global offset between virtual
and actual craniotomy revealed an average shift of 4.5 ± 3.6 mm. The results validated
the ‘elective single-stage cranioplasty’ technique as a state-of-the-art virtual
planning method and surgical workflow. This patient-tailored workflow could significantly
reduce surgical times compared to the traditional, intraoperative acrylic moulding
method and may be an option for the reconstruction of bone defects in the craniofacial
region.

text: "Form versus function is a long-standing debate in various design-related
fields, such as architecture as well as graphic and industrial design. A good
design that balances form and function often requires considerable human effort
and collaboration among experts from different professional fields. Computational
design tools provide a new paradigm for designing functional objects. In computational
design, form and function are represented as mathematical\r\nquantities, with
the help of numerical and combinatorial algorithms, they can assist even novice
users in designing versatile models that exhibit their desired functionality.
This thesis presents three disparate research studies on the computational design
of functional objects: The appearance of 3d print—we optimize the volumetric material
distribution for faithfully replicating colored surface texture in 3d printing;
the dynamic motion of mechanical structures—\r\nour design system helps the novice
user to retarget various mechanical templates with different functionality to
complex 3d shapes; and a more abstract functionality, multistability—our algorithm
automatically generates models that exhibit multiple stable target poses. For
each of these cases, our computational design tools not only ensure the functionality
of the results but also permit the user aesthetic freedom over the form. Moreover,
fabrication constraints\r\nwere taken into account, which allow for the immediate
creation of physical realization via 3D printing or laser cutting."

text: "Fabrication of curved shells plays an important role in modern design, industry,
and science. Among their remarkable properties are, for example, aesthetics of
organic shapes, ability to evenly distribute loads, or efficient flow separation.
They find applications across vast length scales ranging from sky-scraper architecture
to microscopic devices. But, at\r\nthe same time, the design of curved shells
and their manufacturing process pose a variety of challenges. In this thesis,
they are addressed from several perspectives. In particular, this thesis presents
approaches based on the transformation of initially flat sheets into the target
curved surfaces. This involves problems of interactive design of shells with nontrivial
mechanical constraints, inverse design of complex structural materials, and data-driven
modeling of delicate and time-dependent physical properties. At the same time,
two newly-developed self-morphing mechanisms targeting flat-to-curved transformation
are presented.\r\nIn architecture, doubly curved surfaces can be realized as cold
bent glass panelizations. Originally flat glass panels are bent into frames and
remain stressed. This is a cost-efficient fabrication approach compared to hot
bending, when glass panels are shaped plastically. However such constructions
are prone to breaking during bending, and it is highly\r\nnontrivial to navigate
the design space, keeping the panels fabricable and aesthetically pleasing at
the same time. We introduce an interactive design system for cold bent glass façades,
while previously even offline optimization for such scenarios has not been sufficiently
developed. Our method is based on a deep learning approach providing quick\r\nand
high precision estimation of glass panel shape and stress while handling the shape\r\nmultimodality.\r\nFabrication
of smaller objects of scales below 1 m, can also greatly benefit from shaping
originally flat sheets. In this respect, we designed new self-morphing shell mechanisms
transforming from an initial flat state to a doubly curved state with high precision
and detail. Our so-called CurveUps demonstrate the encodement of the geometric
information\r\ninto the shell. Furthermore, we explored the frontiers of programmable
materials and showed how temporal information can additionally be encoded into
a flat shell. This allows prescribing deformation sequences for doubly curved
surfaces and, thus, facilitates self-collision avoidance enabling complex shapes
and functionalities otherwise impossible.\r\nBoth of these methods include inverse
design tools keeping the user in the design loop."

text: "Cold bent glass is a promising and cost-efficient method for realizing doubly
curved glass facades. They are produced by attaching planar glass sheets to curved
frames and require keeping the occurring stress within safe limits.\r\nHowever,
it is very challenging to navigate the design space of cold bent glass panels
due to the fragility of the material, which impedes the form-finding for practically
feasible and aesthetically pleasing cold bent glass facades. We propose an interactive,
data-driven approach for designing cold bent glass facades that can be seamlessly
integrated into a typical architectural design pipeline. Our method allows non-expert
users to interactively edit a parametric surface while providing real-time feedback
on the deformed shape and maximum stress of cold bent glass panels. Designs are
automatically refined to minimize several fairness criteria while maximal stresses
are kept within glass limits. We achieve interactive frame rates by using a differentiable
Mixture Density Network trained from more than a million simulations. Given a
curved boundary, our regression model is capable of handling multistable\r\nconfigurations
and accurately predicting the equilibrium shape of the panel and its corresponding
maximal stress. We show predictions are highly accurate and validate our results
with a physical realization of a cold bent glass surface."

text: Advances in shape-morphing materials, such as hydrogels, shape-memory polymers
and light-responsive polymers have enabled prescribing self-directed deformations
of initially flat geometries. However, most proposed solutions evolve towards
a target geometry without considering time-dependent actuation paths. To achieve
more complex geometries and avoid self-collisions, it is critical to encode a
spatial and temporal shape evolution within the initially flat shell. Recent realizations
of time-dependent morphing are limited to the actuation of few, discrete hinges
and cannot form doubly curved surfaces. Here, we demonstrate a method for encoding
temporal shape evolution in architected shells that assume complex shapes and
doubly curved geometries. The shells are non-periodic tessellations of pre-stressed
contractile unit cells that soften in water at rates prescribed locally by mesostructure
geometry. The ensuing midplane contraction is coupled to the formation of encoded
curvatures. We propose an inverse design tool based on a data-driven model for
unit cells’ temporal responses.

text: "The “procedural” approach to animating ocean waves is the dominant algorithm
for animating larger bodies of water in\r\ninteractive applications as well as
in off-line productions — it provides high visual quality with a low computational
demand. In this paper, we widen the applicability of procedural water wave animation
with an extension that guarantees the satisfaction of boundary conditions imposed
by terrain while still approximating physical wave behavior. In combination with
a particle system that models wave breaking, foam, and spray, this allows us to
naturally model waves interacting with beaches and rocks. Our system is able to
animate waves at large scales at interactive frame rates on a commodity PC."

text: "Commercially available full-color 3D printing allows for detailed control
of material deposition in a volume, but an exact reproduction of a target surface
appearance is hampered by the strong subsurface scattering that causes nontrivial
volumetric cross-talk at the print surface. Previous work showed how an iterative
optimization scheme based on accumulating absorptive materials at the surface
can be used to find a volumetric distribution of print materials that closely
approximates a given target appearance.\r\n\r\nIn this work, we first revisit
the assumption that pushing the absorptive materials to the surface results in
minimal volumetric cross-talk. We design a full-fledged optimization on a small
domain for this task and confirm this previously reported heuristic. Then, we
extend the above approach that is critically limited to color reproduction on
planar surfaces, to arbitrary 3D shapes. Our method enables high-fidelity color
texture reproduction on 3D prints by effectively compensating for internal light
scattering within arbitrarily shaped objects. In addition, we propose a content-aware
gamut mapping that significantly improves color reproduction for the pathological
case of thin geometric features. Using a wide range of sample objects with complex
textures and geometries, we demonstrate color reproduction whose fidelity is superior
to state-of-the-art drivers for color 3D printers."

text: We propose a novel technique for the automatic design of molds to cast highly
complex shapes. The technique generates composite, two-piece molds. Each mold
piece is made up of a hard plastic shell and a flexible silicone part. Thanks
to the thin, soft, and smartly shaped silicone part, which is kept in place by
a hard plastic shell, we can cast objects of unprecedented complexity. An innovative
algorithm based on a volumetric analysis defines the layout of the internal cuts
in the silicone mold part. Our approach can robustly handle thin protruding features
and intertwined topologies that have caused previous methods to fail. We compare
our results with state of the art techniques, and we demonstrate the casting of
shapes with extremely complex geometry.

text: 'Bending-active structures are able to efficiently produce complex curved
shapes starting from flat panels. The desired deformation of the panels derives
from the proper selection of their elastic properties. Optimized panels, called
FlexMaps, are designed such that, once they are bent and assembled, the resulting
static equilibrium configuration matches a desired input 3D shape. The FlexMaps
elastic properties are controlled by locally varying spiraling geometric mesostructures,
which are optimized in size and shape to match the global curvature (i.e., bending
requests) of the target shape. The design pipeline starts from a quad mesh representing
the input 3D shape, which defines the edge size and the total amount of spirals:
every quad will embed one spiral. Then, an optimization algorithm tunes the geometry
of the spirals by using a simplified pre-computed rod model. This rod model is
derived from a non-linear regression algorithm which approximates the non-linear
behavior of solid FEM spiral models subject to hundreds of load combinations.
This innovative pipeline has been applied to the project of a lightweight plywood
pavilion named FlexMaps Pavilion, which is a single-layer piecewise twisted arc
that fits a bounding box of 3.90x3.96x3.25 meters.'

text: We propose a novel generic shape optimization method for CAD models based
on the eXtended Finite Element Method (XFEM). Our method works directly on the
intersection between the model and a regular simulation grid, without the need
to mesh or remesh, thus removing a bottleneck of classical shape optimization
strategies. This is made possible by a novel hierarchical integration scheme that
accurately integrates finite element quantities with sub-element precision. For
optimization, we efficiently compute analytical shape derivatives of the entire
framework, from model intersection to integration rule generation and XFEM simulation.
Moreover, we describe a differentiable projection of shape parameters onto a constraint
manifold spanned by user-specified shape preservation, consistency, and manufacturability
constraints. We demonstrate the utility of our approach by optimizing mass distribution,
strength-to-weight ratio, and inverse elastic shape design objectives directly
on parameterized 3D CAD models.

text: "Additive manufacturing has recently seen drastic improvements in resolution,
making it now possible to fabricate features at scales of hundreds or even dozens
of nanometers, which previously required very expensive lithographic methods.\r\nAs
a result, additive manufacturing now seems poised for optical applications, including
those relevant to computer graphics, such as material design, as well as display
and imaging applications.\r\n \r\nIn this work, we explore the use of additive
manufacturing for generating structural colors, where the structures are designed
using a fabrication-aware optimization process.\r\nThis requires a combination
of full-wave simulation, a feasible parameterization of the design space, and
a tailored optimization procedure.\r\nMany of these components should be re-usable
for the design of other optical structures at this scale.\r\n \r\nWe show initial
results of material samples fabricated based on our designs.\r\nWhile these suffer
from the prototype character of state-of-the-art fabrication hardware, we believe
they clearly demonstrate the potential of additive nanofabrication for structural
colors and other graphics applications."

text: Molding is a popular mass production method, in which the initial expenses
for the mold are offset by the low per-unit production cost. However, the physical
fabrication constraints of the molding technique commonly restrict the shape of
moldable objects. For a complex shape, a decomposition of the object into moldable
parts is a common strategy to address these constraints, with plastic model kits
being a popular and illustrative example. However, conducting such a decomposition
requires considerable expertise, and it depends on the technical aspects of the
fabrication technique, as well as aesthetic considerations. We present an interactive
technique to create such decompositions for two-piece molding, in which each part
of the object is cast between two rigid mold pieces. Given the surface description
of an object, we decompose its thin-shell equivalent into moldable parts by first
performing a coarse decomposition and then utilizing an active contour model for
the boundaries between individual parts. Formulated as an optimization problem,
the movement of the contours is guided by an energy reflecting fabrication constraints
to ensure the moldability of each part. Simultaneously, the user is provided with
editing capabilities to enforce aesthetic guidelines. Our interactive interface
provides control of the contour positions by allowing, for example, the alignment
of part boundaries with object features. Our technique enables a novel workflow,
as it empowers novice users to explore the design space, and it generates fabrication-ready
two-piece molds that can be used either for casting or industrial injection molding
of free-form objects.

text: 'Objective: To report long-term results after Pipeline Embolization Device
(PED) implantation, characterize complex and standard aneurysms comprehensively,
and introduce a modified flow disruption scale. Methods: We retrospectively reviewed
a consecutive series of 40 patients harboring 59 aneurysms treated with 54 PEDs.
Aneurysm complexity was assessed using our proposed classification. Immediate
angiographic results were analyzed using previously published grading scales and
our novel flow disruption scale. Results: According to our new definition, 46
(78%) aneurysms were classified as complex. Most PED interventions were performed
in the paraophthalmic and cavernous internal carotid artery segments. Excellent
neurologic outcome (modified Rankin Scale 0 and 1) was observed in 94% of patients.
Our data showed low permanent procedure-related mortality (0%) and morbidity (3%)
rates. Long-term angiographic follow-up showed complete occlusion in 81% and near-total
obliteration in a further 14%. Complete obliteration after deployment of a single
PED was achieved in all standard aneurysms with 1-year follow-up. Our new scale
was an independent predictor of aneurysm occlusion in a multivariable analysis.
All aneurysms with a high flow disruption grade showed complete occlusion at follow-up
regardless of PED number or aneurysm complexity. Conclusions: Treatment with the
PED should be recognized as a primary management strategy for a highly selected
cohort with predominantly complex intracranial aneurysms. We further show that
a priori assessment of aneurysm complexity and our new postinterventional angiographic
flow disruption scale predict occlusion probability and may help to determine
the adequate number of per-aneurysm devices.'

text: We present a data-driven technique to instantly predict how fluid flows around
various three-dimensional objects. Such simulation is useful for computational
fabrication and engineering, but is usually computationally expensive since it
requires solving the Navier-Stokes equation for many time steps. To accelerate
the process, we propose a machine learning framework which predicts aerodynamic
forces and velocity and pressure fields given a threedimensional shape input.
Handling detailed free-form three-dimensional shapes in a data-driven framework
is challenging because machine learning approaches usually require a consistent
parametrization of input and output. We present a novel PolyCube maps-based parametrization
that can be computed for three-dimensional shapes at interactive rates. This allows
us to efficiently learn the nonlinear response of the flow using a Gaussian process
regression. We demonstrate the effectiveness of our approach for the interactive
design and optimization of a car body.

text: We propose a new method for fabricating digital objects through reusable silicone
molds. Molds are generated by casting liquid silicone into custom 3D printed containers
called metamolds. Metamolds automatically define the cuts that are needed to extract
the cast object from the silicone mold. The shape of metamolds is designed through
a novel segmentation technique, which takes into account both geometric and topological
constraints involved in the process of mold casting. Our technique is simple,
does not require changing the shape or topology of the input objects, and only
requires off-the- shelf materials and technologies. We successfully tested our
method on a set of challenging examples with complex shapes and rich geometric
detail. © 2018 Association for Computing Machinery.

text: We propose FlexMaps, a novel framework for fabricating smooth shapes out of
flat, flexible panels with tailored mechanical properties. We start by mapping
the 3D surface onto a 2D domain as in traditional UV mapping to design a set of
deformable flat panels called FlexMaps. For these panels, we design and obtain
specific mechanical properties such that, once they are assembled, the static
equilibrium configuration matches the desired 3D shape. FlexMaps can be fabricated
from an almost rigid material, such as wood or plastic, and are made flexible
in a controlled way by using computationally designed spiraling microstructures.

text: Digital fabrication devices are powerful tools for creating tangible reproductions
of 3D digital models. Most available printing technologies aim at producing an
accurate copy of a tridimensional shape. However, fabrication technologies can
also be used to create a stylistic representation of a digital shape. We refer
to this class of methods as ‘stylized fabrication methods’. These methods abstract
geometric and physical features of a given shape to create an unconventional representation,
to produce an optical illusion or to devise a particular interaction with the
fabricated model. In this state‐of‐the‐art report, we classify and overview this
broad and emerging class of approaches and also propose possible directions for
future research.

text: In the context of robotic manipulation and grasping, the shift from a view
that is static (force closure of a single posture) and contact-deprived (only
contact for force closure is allowed, everything else is obstacle) towards a view
that is dynamic and contact-rich (soft manipulation) has led to an increased interest
in soft hands. These hands can easily exploit environmental constraints and object
surfaces without risk, and safely interact with humans, but present also some
challenges. Designing them is difficult, as well as predicting, modelling, and
“programming” their interactions with the objects and the environment. This paper
tackles the problem of simulating them in a fast and effective way, leveraging
on novel and existing simulation technologies. We present a triple-layered simulation
framework where dynamic properties such as stiffness are determined from slow
but accurate FEM simulation data once, and then condensed into a lumped parameter
model that can be used to fast simulate soft fingers and soft hands. We apply
our approach to the simulation of soft pneumatic fingers.

text: Color texture reproduction in 3D printing commonly ignores volumetric light
transport (cross-talk) between surface points on a 3D print. Such light diffusion
leads to significant blur of details and color bleeding, and is particularly severe
for highly translucent resin-based print materials. Given their widely varying
scattering properties, this cross-talk between surface points strongly depends
on the internal structure of the volume surrounding each surface point. Existing
scattering-aware methods use simplified models for light diffusion, and often
accept the visual blur as an immutable property of the print medium. In contrast,
our work counteracts heterogeneous scattering to obtain the impression of a crisp
albedo texture on top of the 3D print, by optimizing for a fully volumetric material
distribution that preserves the target appearance. Our method employs an efficient
numerical optimizer on top of a general Monte-Carlo simulation of heterogeneous
scattering, supported by a practical calibration procedure to obtain scattering
parameters from a given set of printer materials. Despite the inherent translucency
of the medium, we reproduce detailed surface textures on 3D prints. We evaluate
our system using a commercial, five-tone 3D print process and compare against
the printer’s native color texturing mode, demonstrating that our method preserves
high-frequency features well without having to compromise on color gamut.

text: " We present an interactive design system to create functional mechanical
\ objects. Our computational approach allows novice users to retarget an existing
mechanical template to a user-specified input shape. Our proposed representation
for a mechanical template encodes a parameterized mechanism, mechanical constraints
that ensure a physically valid configuration, spatial relationships of mechanical
parts to the user-provided shape, and functional constraints that specify an intended
functionality. We provide an intuitive interface and optimization-in-the-loop
approach for finding a valid configuration of the mechanism and the shape to
ensure that higher-level functional goals are met. Our algorithm interactively
optimizes the mechanism while the user manipulates the placement of mechanical
components and the shape. Our system allows users to efficiently explore various
design choices and to synthesize customized mechanical objects that can be fabricated
with rapid prototyping technologies. We demonstrate the efficacy of our approach
by retargeting various mechanical templates to different shapes and fabricating
the resulting functional mechanical objects.\r\n"

text: We present a computational approach for designing CurveUps, curvy shells that
form from an initially flat state. They consist of small rigid tiles that are
tightly held together by two pre-stretched elastic sheets attached to them. Our
method allows the realization of smooth, doubly curved surfaces that can be fabricated
as a flat piece. Once released, the restoring forces of the pre-stretched sheets
support the object to take shape in 3D. CurveUps are structurally stable in their
target configuration. The design process starts with a target surface. Our method
generates a tile layout in 2D and optimizes the distribution, shape, and attachment
areas of the tiles to obtain a configuration that is fabricable and in which the
curved up state closely matches the target. Our approach is based on an efficient
approximate model and a local optimization strategy for an otherwise intractable
nonlinear optimization problem. We demonstrate the effectiveness of our approach
for a wide range of shapes, all realized as physical prototypes.

text: We present an interactive system for computational design, optimization, and
fabrication of multicopters. Our computational approach allows non-experts to
design, explore, and evaluate a wide range of different multicopters. We provide
users with an intuitive interface for assembling a multicopter from a collection
of components (e.g., propellers, motors, and carbon fiber rods). Our algorithm
interactively optimizes shape and controller parameters of the current design
to ensure its proper operation. In addition, we allow incorporating a variety
of other metrics (such as payload, battery usage, size, and cost) into the design
process and exploring tradeoffs between them. We show the efficacy of our method
and system by designing, optimizing, fabricating, and operating multicopters with
complex geometries and propeller configurations. We also demonstrate the ability
of our optimization algorithm to improve the multicopter performance under different
metrics.

text: We present FlexMolds, a novel computational approach to automatically design
flexible, reusable molds that, once 3D printed, allow us to physically fabricate,
by means of liquid casting, multiple copies of complex shapes with rich surface
details and complex topology. The approach to design such flexible molds is based
on a greedy bottom-up search of possible cuts over an object, evaluating for each
possible cut the feasibility of the resulting mold. We use a dynamic simulation
approach to evaluate candidate molds, providing a heuristic to generate forces
that are able to open, detach, and remove a complex mold from the object it surrounds.
We have tested the approach with a number of objects with nontrivial shapes and
topologies.

text: We present a novel optimization-based algorithm for the design and fabrication
of customized, deformable input devices, capable of continuously sensing their
deformation. We propose to embed piezoresistive sensing elements into flexible
3D printed objects. These sensing elements are then utilized to recover rich and
natural user interactions at runtime. Designing such objects is a challenging
and hard problem if attempted manually for all but the simplest geometries and
deformations. Our method simultaneously optimizes the internal routing of the
sensing elements and computes a mapping from low-level sensor readings to user-specified
outputs in order to minimize reconstruction error. We demonstrate the power and
flexibility of the approach by designing and fabricating a set of flexible input
devices. Our results indicate that the optimization-based design greatly outperforms
manual routings in terms of reconstruction accuracy and thus interaction fidelity.

text: We present a computational method for designing wire sculptures consisting
of interlocking wires. Our method allows the computation of aesthetically pleasing
structures that are structurally stable, efficiently fabricatable with a 2D wire
bending machine, and assemblable without the need of additional connectors. Starting
from a set of planar contours provided by the user, our method automatically tests
for the feasibility of a design, determines a discrete ordering of wires at intersection
points, and optimizes for the rest shape of the individual wires to maximize structural
stability under frictional contact. In addition to their application to art, wire
sculptures present an extremely efficient and fast alternative for low-fidelity
rapid prototyping because manufacturing time and required material linearly scales
with the physical size of objects. We demonstrate the effectiveness of our approach
on a varied set of examples, all of which we fabricated.

text: In this paper, we present a method to model hyperelasticity that is well suited
for representing the nonlinearity of real-world objects, as well as for estimating
it from deformation examples. Previous approaches suffer several limitations,
such as lack of integrability of elastic forces, failure to enforce energy convexity,
lack of robustness of parameter estimation, or difficulty to model cross-modal
effects. Our method avoids these problems by relying on a general energy-based
definition of elastic properties. The accuracy of the resulting elastic model
is maximized by defining an additive model of separable energy terms, which allow
progressive parameter estimation. In addition, our method supports efficient modeling
of extreme nonlinearities thanks to energy-limiting constraints. We combine our
energy-based model with an optimization method to estimate model parameters from
force-deformation examples, and we show successful modeling of diverse deformable
objects, including cloth, human finger skin, and internal human anatomy in a medical
imaging application.

text: The accuracy of interdisciplinarity measurements is directly related to the
quality of the underlying bibliographic data. Existing indicators of interdisciplinarity
are not capable of reflecting the inaccuracies introduced by incorrect and incomplete
records because correct and complete bibliographic data can rarely be obtained.
This is the case for the Rao–Stirling index, which cannot handle references that
are not categorized into disciplinary fields. We introduce a method that addresses
this problem. It extends the Rao–Stirling index to acknowledge missing data by
calculating its interval of uncertainty using computational optimization. The
evaluation of our method indicates that the uncertainty interval is not only useful
for estimating the inaccuracy of interdisciplinarity measurements, but it also
delivers slightly more accurate aggregated interdisciplinarity measurements than
the Rao–Stirling index.

text: Creating mechanical automata that can walk in stable and pleasing manners
is a challenging task that requires both skill and expertise. We propose to use
computational design to offset the technical difficulties of this process. A simple
drag-and-drop interface allows casual users to create personalized walking toys
from a library of pre-defined template mechanisms. Provided with this input, our
method leverages physical simulation and evolutionary optimization to refine the
mechanical designs such that the resulting toys are able to walk. The optimization
process is guided by an intuitive set of objectives that measure the quality of
the walking motions. We demonstrate our approach on a set of simulated mechanical
toys with different numbers of legs and various distinct gaits. Two fabricated
prototypes showcase the feasibility of our designs.

text: In recent years we have seen numerous improvements on 3D scanning and tracking
of human faces, greatly advancing the creation of digital doubles for film and
video games. However, despite the high-resolution quality of the reconstruction
approaches available, current methods are unable to capture one of the most important
regions of the face - the eye region. In this work we present the first method
for detailed spatio-temporal reconstruction of eyelids. Tracking and reconstructing
eyelids is extremely challenging, as this region exhibits very complex and unique
skin deformation where skin is folded under while opening the eye. Furthermore,
eyelids are often only partially visible and obstructed due to selfocclusion and
eyelashes. Our approach is to combine a geometric deformation model with image
data, leveraging multi-view stereo, optical flow, contour tracking and wrinkle
detection from local skin appearance. Our deformation model serves as a prior
that enables reconstruction of eyelids even under strong self-occlusions caused
by rolling and folding skin as the eye opens and closes. The output is a person-specific,
time-varying eyelid reconstruction with anatomically plausible deformations. Our
high-resolution detailed eyelids couple naturally with current facial performance
capture approaches. As a result, our method can largely increase the fidelity
of facial capture and the creation of digital doubles.

text: This paper introduces "OmniAD," a novel data-driven pipeline to
model and acquire the aerodynamics of three-dimensional rigid objects. Traditionally,
aerodynamics are examined through elaborate wind tunnel experiments or expensive
fluid dynamics computations, and are only measured for a small number of discrete
wind directions. OmniAD allows the evaluation of aerodynamic forces, such as drag
and lift, for any incoming wind direction using a novel representation based on
spherical harmonics. Our datadriven technique acquires the aerodynamic properties
of an object simply by capturing its falling motion using a single camera. Once
model parameters are estimated, OmniAD enables realistic realtime simulation of
rigid bodies, such as the tumbling and gliding of leaves, without simulating the
surrounding air. In addition, we propose an intuitive user interface based on
OmniAD to interactively design three-dimensional kites that actually fly. Various
nontraditional kites were designed to demonstrate the physical validity of our
model.

text: We propose a method for fabricating deformable objects with spatially varying
elasticity using 3D printing. Using a single, relatively stiff printer material,
our method designs an assembly of smallscale microstructures that have the effect
of a softer material at the object scale, with properties depending on the microstructure
used in each part of the object. We build on work in the area of metamaterials,
using numerical optimization to design tiled microstructures with desired properties,
but with the key difference that our method designs families of related structures
that can be interpolated to smoothly vary the material properties over a wide
range. To create an object with spatially varying elastic properties, we tile
the object's interior with microstructures drawn from these families, generating
a different microstructure for each cell using an efficient algorithm to select
compatible structures for neighboring cells. We show results computed for both
2D and 3D objects, validating several 2D and 3D printed structures using standard
material tests as well as demonstrating various example applications.

text: We present a computational tool for fabrication-oriented design of flexible
rod meshes. Given a deformable surface and a set of deformed poses as input, our
method automatically computes a printable rod mesh that, once manufactured, closely
matches the input poses under the same boundary conditions. The core of our method
is formed by an optimization scheme that adjusts the cross-sectional profiles
of the rods and their rest centerline in order to best approximate the target
deformations. This approach allows us to locally control the bending and stretching
resistance of the surface with a single material, yielding high design flexibility
and low fabrication cost.

text: Facial appearance capture is now firmly established within academic research
and used extensively across various application domains, perhaps most prominently
in the entertainment industry through the design of virtual characters in video
games and films. While significant progress has occurred over the last two decades,
no single survey currently exists that discusses the similarities, differences,
and practical considerations of the available appearance capture techniques as
applied to human faces. A central difficulty of facial appearance capture is the
way light interacts with skin-which has a complex multi-layered structure-and
the interactions that occur below the skin surface can, by definition, only be
observed indirectly. In this report, we distinguish between two broad strategies
for dealing with this complexity. "Image-based methods" try to exhaustively
capture the exact face appearance under different lighting and viewing conditions,
and then render the face through weighted image combinations. "Parametric
methods" instead fit the captured reflectance data to some parametric appearance
model used during rendering, allowing for a more lightweight and flexible representation
but at the cost of potentially increased rendering complexity or inexact reproduction.
The goal of this report is to provide an overview that can guide practitioners
and researchers in assessing the tradeoffs between current approaches and identifying
directions for future advances in facial appearance capture.
