SUMMARY:Sparse Cholesky Updates for Interactive Mesh Parameterization
DESCRIPTION:Technical Papers, Technical Papers Q&A\n\nSparse Cholesky Upda
tes for Interactive Mesh Parameterization\n\nHerholz, Sorkine-Hornung\n\nW
e present a novel linear solver for interactive parameterization tasks. Ou
r method is based on the observation that quasi-conformal parameterization
s of a triangle mesh are largely determined by boundary conditions. These
boundary conditions are typically constructed interactively by a user who
has to take several artistic and geometric constraints into account while
introducing cuts on the geometry. Commonly, the main computational burden
in these methods is solving a linear system every time new boundary condit
ions are imposed. The core of our solver is a novel approach to efficientl
y update the Cholesky factorization of the linear system to reflect new bo
undary conditions, thereby enabling a seamless and interactive workflow ev
en for larger meshes consisting of several millions of vertices.\n\nRegist
