A Tracing Algorithm for Surface-Surface Intersections on Surface Boundaries

In this paper we present an algorithm with a new trace-terminatingcondition for tracing along surface-surface intersection curves onsurface boundaries, while several tracing methods and embedding methodsthat include tracing scheme may cause false termination with atraditional trace-terminating condition: tracing stops when thesurface-domain's boundary is reached. And we also suggest anotheriterative method to calculate intersection points on surface boundarieswith parallel surface normal. Some numerical examples with these twoideas and comparisons to `DESIGNBASE', `ACIS', and `Parasolid' areincluded to demonstrate the effectiveness of our algorithm.
