Abstract

Plane, quadric surfaces are fundamental elements of three-dimension geometric modeling systems. Intersecting between them is the most basic operation in the system. In this paper, the intersection algorithms in GEMS 4.0 modeling system are discussed, and the method of calculating valid parameter interval to obtain valid intersection curve segments is advanced. At the end, how to calculate the NURBS parameter of intersection point is given.
