Singularity Computation for Rational Parametric Surfaces Using Moving Planes
2022
ACM Transactions on Graphics
Singularity computation is a fundamental problem in Computer Graphics and Computer Aided Geometric Design, since it is closely related to topology determination, intersection, mesh generation, rendering, simulation and modeling of curves and surfaces. In this paper, we present an efficient and robust algorithm for computing all the singularities (including their orders) of rational parametric surfaces using the technique of moving planes. The main approach is first to construct a representation
