摘要
In this paper we present an algorithm with a new trace-terminating conditionfor tracing along surface-surface intersection curves on surface boundaries, while several tracingmethods and embedding methods that include tracing scheme may cause false termination with atraditional trace-terminating condition: tracing stops when the surface-domain's boundary isreached. And we also suggest another iterative method to calculate intersection points on surfaceboundaries with parallel surface normal. Some numerical examples with these two ideas andcomparisons to 'DESIGNBASE', 'ACIS', and 'Parasolid' are included to demonstrate the effectivenessof our algorithm.
