Presentation
Exact predicates, exact constructions and combinatorics for mesh CSG
SessionGeometry Processing
DescriptionThis 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 contribution is a 2D Constrained Delaunay Triangulation with exact coordinates and symbolic perturbations to disambiguate configurations with co-cyclic points.
