SUMMARY:Geometry Processing
DESCRIPTION:Exact predicates, exact constructions and combinatorics for me
 sh CSG\n\nThis article introduces an algorithm that exactly constructs the
  so-called Weiler model (also called a 3D mesh arrangement) and that uses 
 it to implement CSG with arbitrary multi-operand expressions. The main con
 tribution is a 2D Constrained Delaunay Triangulation with exact coordinate
 s and symbolic...\n\n\nBruno Levy (Inria Saclay and Laboratoire de Mathéma

 ess rate. A novel input "chamfering" that eliminates all acute angles guar

 \n\nPR-Cage is an automated framework for generating high-quality cages—si

 rocessing\n\nThis work demonstrates how to hoist textures to vertex color 
 to allow for incorporating textures into geometry processing algorithms. T
 he use of vertex colors for texture-aware results is then shown across a n
 umber of algorithms, including parameterization, clustering, remeshing, an
 d others.\n\n\nJulian Knodt and Seung-Hwan Baek (POSTECH) and Julian Knodt
