SUMMARY:Digital Geometry Processing
DESCRIPTION:Technical Papers, Technical Papers Q&A\n\nShape Approximation
by Developable Wrapping\n\nIon, Rabinovich, Herholz, Sorkine-Hornung\n\nWe
present an automatic tool to approximate curved geometries with piecewise
developable surfaces. At the center of our work is an algorithm that wrap
s a given 3D input surface with multiple developable patches, each modeled
as a discrete orthogonal geodesic net. Our algorithm features a global op
ti...\n\n---------------------\nOpening and Closing Surfaces\n\nSellĂˇn, Ke
sten, Ang, Jacobson\n\nWe propose a new type of curvature flow for curves
in 2D and surfaces in 3D. The flow is inspired by the mathematical morphol
ogy opening and closing operations. These operations are classically defin
ed by composition of dilation and erosion operations. In practice, existin
g methods implemented this ...\n\n---------------------\nConstructing 3D S
elf-Supporting Surfaces with Isotropic Stress Using 4D Minimal Hypersurfac
es of Revolution\n\nMa, He, Sun, Zhou, Zhang...\n\nWe formulate the over-c
onstrained 3D equilibrium problem into a volume minimization problem in 4D
and figure out a sufficient condition of 3D self-supporting structures wi
th isotropic stresses.\n\n---------------------\nSparse Cholesky Updates f
or Interactive Mesh Parameterization\n\nHerholz, Sorkine-Hornung\n\nWe pre
sent a novel linear solver for interactive parameterization tasks. Our met
hod is based on the observation that quasi-conformal parameterizations of
a triangle mesh are largely determined by boundary conditions. These bound
ary conditions are typically constructed interactively by a user who has..
.\n\n---------------------\nTo cut or to fill: a global optimization appro
ach to topological simplification\n\nZeng, Chambers, Letscher, Ju\n\nWe pr
esent a novel algorithm for simplifying the topology of a 3D shape, which
is characterized by the number of connected components, handles, and cavit
ies. Existing methods either limit their modifications to be only cutting
or only filling, or take a heuristic approach to decide where to cut or f.
..\n\n---------------------\nNonlinear Spectral Geometry Processing via th
e TV Transform\n\nFumero, Moeller, RodolĂ \n\nWe introduce a novel computat
ional framework for digital geometry processing, based upon the derivation
of a nonlinear operator associated to the total variation functional. Suc
h operator admits a generalized notion of spectral decomposition, yielding
a sparse multiscale representation akin to Lapla...\n\n\nRegistration Cat
