摘要
在虚拟加工环境中 ,毛坯的三维图形处理主要包括毛坯三维图形的几何建模方法、三维几何图形的显示数据结构和三维图形的编译处理等 ,提出了一种能够满足虚拟加工环境的三维图形的数据结构 ,给出了实现方案 。
The key technical problem of roughcast in the virtual machining environment is to handle three-dimensional shape, which includes the method of setting up geometrical model of three-dimensional shape of roughcast, the data structure that displays three-dimensional shape, process compiling three-dimensional shape, etc. This paper offers a kind of data structure of three-dimensional shape that can satisfy the virtual machining environment. This data structure realizes the functions of calling the environment of three-dimensional shape, butting blanks, etc.
