| 摘 要： | 八叉树模型是表达三维实体的一种方法。本文提出了一个由三维实体的ＣＳＧ模型转换到八叉树模型的算法。该算法采用动态分解策略，利用长整数的“位”来记录结点的状态信息，从而较大地节省了存储量并较好地弥补了八叉树模型存储量大的缺陷。

| Abstract: | Octree model is an expressive method for three dimensional object. This paper presents an algorithm for converting the CSG model of three dimensional object to Octree model by dynamic decomposed strategy. Because the node's information is recorded by the integer's bit,the memory requirement can be cut down greatly and the shortcoming of Octree model is madeup well. The good result can be obtained by the algorithm. |
