text: We propose an interactive sculpting system for seamlessly editing pre-computed
animations of liquid, without the need for any resimulation. The input is a sequence
of meshes without correspondences representing the liquid surface over time. Our
method enables the efficient selection of consistent space-time parts of this
animation, such as moving waves or droplets, which we call space-time features.
Once selected, a feature can be copied, edited, or duplicated and then pasted
back anywhere in space and time in the same or in another liquid animation sequence.
Our method circumvents tedious user interactions by automatically computing the
spatial and temporal ranges of the selected feature. We also provide space-time
shape editing tools for non-uniform scaling, rotation, trajectory changes, and
temporal editing to locally speed up or slow down motion. Using our tools, the
user can edit and progressively refine any input simulation result, possibly using
a library of precomputed space-time features extracted from other animations.
In contrast to the trial-and-error loop usually required to edit animation results
through the tuning of indirect simulation parameters, our method gives the user
full control over the edited space-time behaviors. © 2016 Copyright held by the

text: In this paper we introduce the Multiobjective Optimization Hierarchic Genetic
Strategy with maturing (MO-mHGS), a meta-algorithm that performs evolutionary
optimization in a hierarchy of populations. The maturing mechanism improves growth
and reduces redundancy. The performance of MO-mHGS with selected state-of-the-art
multiobjective evolutionary algorithms as internal algorithms is analysed on benchmark
problems and their modifications for which single fitness evaluation time depends
on the solution accuracy. We compare the proposed algorithm with the Island Model
Genetic Algorithm as well as with single-deme methods, and discuss the impact
of internal algorithms on the MO-mHGS meta-algorithm. © 2016 Elsevier B.V.

text: When aiming to seamlessly integrate a fluid simulation into a larger scenario
(like an open ocean), careful attention must be paid to boundary conditions. In
particular, one must implement special "non-reflecting" boundary conditions,
which dissipate out-going waves as they exit the simulation. Unfortunately, the
state of the art in non-reflecting boundary conditions (perfectly-matched layers,
or PMLs) only permits trivially simple inflow/outflow conditions, so there is
no reliable way to integrate a fluid simulation into a more complicated environment
like a stormy ocean or a turbulent river. This paper introduces the first method
for combining nonreflecting boundary conditions based on PMLs with inflow/outflow
boundary conditions that vary arbitrarily throughout space and time. Our algorithm
is a generalization of stateof- the-art mean-flow boundary conditions in the computational
fluid dynamics literature, and it allows for seamless integration of a fluid simulation
into much more complicated environments. Our method also opens the door for previously-unseen
postprocess effects like retroactively changing the location of solid obstacles,
and locally increasing the visual detail of a pre-existing simulation.

text: We propose a novel surface-only technique for simulating incompressible, inviscid
and uniform-density liquids with surface tension in three dimensions. The liquid
surface is captured by a triangle mesh on which a Lagrangian velocity field is
stored. Because advection of the velocity field may violate the incompressibility
condition, we devise an orthogonal projection technique to remove the divergence
while requiring the evaluation of only two boundary integrals. The forces of surface
tension, gravity, and solid contact are all treated by a boundary element solve,
allowing us to perform detailed simulations of a wide range of liquid phenomena,
including waterbells, droplet and jet collisions, fluid chains, and crown splashes.

text: Combining high-resolution level set surface tracking with lower resolution
physics is an inexpensive method for achieving highly detailed liquid animations.
Unfortunately, the inherent resolution mismatch introduces several types of disturbing
visual artifacts. We identify the primary sources of these artifacts and present
simple, efficient, and practical solutions to address them. First, we propose
an unconditionally stable filtering method that selectively removes sub-grid surface
artifacts not seen by the fluid physics, while preserving fine detail in dynamic
splashing regions. It provides comparable results to recent error-correction techniques
at lower cost, without substepping, and with better scaling behavior. Second,
we show how a modified narrow-band scheme can ensure accurate free surface boundary
conditions in the presence of large resolution mismatches. Our scheme preserves
the efficiency of the narrow-band methodology, while eliminating objectionable
stairstep artifacts observed in prior work. Third, we demonstrate that the use
of linear interpolation of velocity during advection of the high-resolution level
set surface is responsible for visible grid-aligned kinks; we therefore advocate
higher-order velocity interpolation, and show that it dramatically reduces this
artifact. While these three contributions are orthogonal, our results demonstrate
that taken together they efficiently address the dominant sources of visual artifacts
arising with high-resolution embedded liquid surfaces; the proposed approach offers
improved visual quality, a straightforward implementation, and substantially greater
scalability than competing methods.
