等距曲面和运动曲面在cad cam领域中有着重要的应用，在一些时间敏感场合例如数控加工动态仿真，等距曲面和运动曲面等连续变化曲面求交运算已成为这些系统的计算瓶颈，连续变化曲面求交问题的通常解法是采用曲面求交算法反复迭代计算交线，没有考虑连续变化曲面交线之间的相似性进行求交简化，效率上一直不能有很大的提高。 - It presents algorithms to extract the similarity of intersect curve in different offset distance and use ttp to label the topology of surface intersect . the algorithms succeed in combination of tracing method and topology information , and present an optimized offset ssi algorithm . the optimized algorithm pre - processes surfaces to achieve ttp , and decides calculation strategy of starting points by analyzing the properties of ttp on the surface
