text: 'We present an efficient wavefront tracking algorithm for animating bodies
of water that interact with their environment. Our contributions include: a novel
wavefront tracking technique that enables dispersion, refraction, reflection,
and diffraction in the same simulation; a unique multivalued function interpolation
method that enables our simulations to elegantly sidestep the Nyquist limit; a
dispersion approximation for efficiently amplifying the number of simulated waves
by several orders of magnitude; and additional extensions that allow for time-dependent
effects and interactive artistic editing of the resulting animation. Our contributions
combine to give us multitudes more wave details than similar algorithms, while
maintaining high frame rates and allowing close camera zooms.'

text: "We present a method for simulating brittle fracture under the assumptions
of quasi-static linear elastic fracture mechanics (LEFM). Using the boundary element
method (BEM) and Lagrangian crack-fronts, we produce highly detailed fracture
surfaces. The computational cost of the BEM is alleviated by using a low-resolution
mesh and interpolating the resulting stress intensity factors when propagating
the high-resolution crack-front.\r\n\r\nOur system produces physics-based fracture
surfaces with high spatial and temporal resolution, taking spatial variation of
material toughness and/or strength into account. It also allows for crack initiation
to be handled separately from crack propagation, which is not only more reasonable
from a physics perspective, but can also be used to control the simulation.\r\n\r\nSeparating
the resolution of the crack-front from the resolution of the computational mesh
increases the efficiency and therefore the amount of visual detail on the resulting
fracture surfaces. The BEM also allows us to re-use previously computed blocks
of the system matrix."

text: We propose a method for propagating edit operations in 2D vector graphics,
based on geometric relationship functions. These functions quantify the geometric
relationship of a point to a polygon, such as the distance to the boundary or
the direction to the closest corner vertex. The level sets of the relationship
functions describe points with the same relationship to a polygon. For a given
query point, we first determine a set of relationships to local features, construct
all level sets for these relationships, and accumulate them. The maxima of the
resulting distribution are points with similar geometric relationships. We show
extensions to handle mirror symmetries, and discuss the use of relationship functions
as local coordinate systems. Our method can be applied, for example, to interactive
floorplan editing, and it is especially useful for large layouts, where individual
edits would be cumbersome. We demonstrate populating 2D layouts with tens to hundreds
of objects by propagating relatively few edit operations.

text: In this paper, we present a method for non-rigid, partial shape matching in
vector graphics. Given a user-specified query region in a 2D shape, similar regions
are found, even if they are non-linearly distorted. Furthermore, a non-linear
mapping is established between the query regions and these matches, which allows
the automatic transfer of editing operations such as texturing. This is achieved
by a two-step approach. First, pointwise correspondences between the query region
and the whole shape are established. The transformation parameters of these correspondences
are registered in an appropriate transformation space. For transformations between
similar regions, these parameters form surfaces in transformation space, which
are extracted in the second step of our method. The extracted regions may be related
to the query region by a non-rigid transform, enabling non-rigid shape matching.

text: In this paper, we introduce a novel scene representation for the visualization
of large-scale point clouds accompanied by a set of high-resolution photographs.
Many real-world applications deal with very densely sampled point-cloud data,
which are augmented with photographs that often reveal lighting variations and
inaccuracies in registration. Consequently, the high-quality representation of
the captured data, i.e., both point clouds and photographs together, is a challenging
and time-consuming task. We propose a two-phase approach, in which the first (preprocessing)
phase generates multiple overlapping surface patches and handles the problem of
seamless texture generation locally for each patch. The second phase stitches
these patches at render-time to produce a high-quality visualization of the data.
As a result of the proposed localization of the global texturing problem, our
algorithm is more than an order of magnitude faster than equivalent mesh-based
texturing techniques. Furthermore, since our preprocessing phase requires only
a minor fraction of the whole data set at once, we provide maximum flexibility
when dealing with growing data sets.
