对多面体造型中一种快速拼合运算的探讨

STUDY ON FAST CONSTRUCTIVE OPERATION FOR SOLID MODELS REPRESENTED BY POLYHEDRON

在多面体几何造型过程中，当拼合的体素位置处于特定情况下时，本文给出一种快速拼合运算方法──放并、放差拼合运算和阵列放并、放差拼合运算。给出了并、交、差和放并、放差运算的定义，并介绍了实现放并、放差拼合运算和阵列放并、放差拼合运算的算法流程。

While geometric solid models are built, a fast constructive operation algorithm is presented when the constructive primitives are at special position. The algorithm simplifies boolean union and subtract operation and gives an array operation. Thus the efficiency of constructive operation is increased.
