摘要
初始图形交换规范IGES是CAD/CAM系统间通讯的重要方式之一。文章概略了IGES文件的结构及IGES曲面实体数据的含义,给出了在逆向工程系统中识别提取IGES曲面实体数据和利用OpenGL对其显示实现的方法。
IGES(Initial Graphics Exchange Specification) is one of the important cummunication methods between CAD/CAM.The meanings of date structure of IGES file and IGES surface and solid is summarized in the paper.The method to identify and abstract IGES surface and solid date and show of IGES graphics based on OpenGL is given.
