Abstract

A surface-surface intersection method has been developed for free-form parametric surfaces with C1 continuity. An initial set of intersection points is calculated by any kind of iterative method such as Timmer's[1]. Additional points forming spans of the intersection curve(s) are calculated by an incremental method in the parametric space. The intersection curve is defined as a list of points. The final representation for the curve is user defined.
