摘要
定义平面的几何信息和拓扑信息，求出面与面的交线是三维几何形体求交的重要过程，建立在此基础上的实体平面求交的编程技术研究，为解决复杂曲面形体的造型及求交打下基础。
The intersection of three dimension geometry body is based on the solving of the
intersection line of planes each other. So it is very important to definite the message of the plane's
geometry and topology. On the base of it the study of technology of programming in the planes
intersection line of solid body provide a method to solving the modelling of complex curve surface
body.
