Abstract: In CAD/CAM applications, there are several algorithms for intersection between C t and C 2 surfaces.These algorithms depend on the availabi;ity of exact derivatives and cannot handle non-smooth surfaces.This paper presents an intelligent implementation of cross intersection between two C O parametric surfaces.The new algorithm is designed and implemented in three steps.First, it Recomposes the two surfaces adaptively into surface elements within specified level of flatness and locates the potentially intersecting sections of the surfaces.Second step triangulates the potentially intersecting surface pairs by filling (or eliminating) any possible triangulation gaps (or overlaps).It finds the intersections segments between pairs of triangles.Third step assembles the intersection segments into curves of intersection, refines the accuracy of computed intersection points, and compacts the intersection curves by eliminating the redundant collinear points.This implementation requires no human interaction in detecting the intersection curve(s) between them.
