Abstract

This paper presents a marching method for computing inter- section curves between two solids represented by subdivision surfaces of Catmull-Clark or Loop type. It can be used in trimming and boolean op- erations for subdivision surfaces. The main idea is to apply a marching method with geometric interpretation to trace the intersection curves. We first determine all intersecting regions, then find pairs of initial in- tersection points, and trace the intersection curves from the initial inter- section points. Various examples are given to demonstrate the robustness and efficiency of our algorithm.
