  1. In some time - critical situation, continuous ssi is computation bottleneck of some solid modeling system. conventional approach for solving continuous ssi often uses intersection algorithm iteratively without taking the characteristic of the surface into account to simplify computation. the dissertation analyzes the intersect curve structure of continue surface, from the point of intersect curve ' s evolution, it describes the relationship between topology of offset surface intersect curve and topology transmit point ( ttp )

    等距和運動在cad cam領域中有著重要的應用,在一些時間敏感場合例如數控加工動態模擬,等距和運動等連續變化運算已成為這些系統的計算瓶頸,連續變化問題的通常解法是採用演算法反復迭代計算,沒有考慮連續變化間的相似性進行簡化,效率上一直不能有很大的提高。
  2. 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

    本文通過對等距結構進行了大量的分析,從的形成和演化過程,揭示了等距拓撲結構和上特徵點間存在著本質的聯系,提取等距不同offset距離環的相關性,並使用特徵點來標識環的拓撲信息,成功地將拓撲信息和跟蹤法相結合,設計了一種等距優化演算法。
  3. Thirdly, the connection between bezier curves and surfaces and their bbc forms is gained. it is not hard to conclude that the bbc representation of curves and surfaces is the extensive form of bezier curves and surfaces
