Abstract:

Surface intersection is the core task of CAD, it is the necessary path for Boolean operations, boundary representation, and one of the most important factors affecting the stability of CAD systems. The singularity calculation of a surface is essentially the intersection of the surface with itself, and is an important prerequisite for the stability of surface intersection algorithms. This presentation will introduce our long-standing theoretical work on surface intersection, singularity computation, and spline self-intersection, and the application of these works to mesh generation and Boolean operations.
