摘　　要：在快速成型技术中,STL数据模型可视化的实现有着非常重要的作用。文章提出了生成可视化的STL三维实体模型的方法,通过设置相邻三角形面片外法向量夹角的临界值来选取适当的公共顶点,并重新计算其法向量,实现了对STL模型的顶点数据冗余处理和向量光滑处理。采用Visual C++为编程语言,以OpenGL为图形开发工具,开发出一个针对STL数据模型的可视化系统,并在Pro/Engineering,UG等造型软件输出的STL文件中得到了验证。该系统为STL模型的后续处理提供了有力的支持。It is very important to realize the visualization for STL model in Rapid Prototyping. In this paper, the method of generating realistic image view for STL model is proposed. By setting a critical angle to select appropriate common point and recalcu late the vector, the redundancy problem of vertex coordinate in STL model is solved and the model looks smoother. A stereo display system is developed by calling functions from OpenGL graphic library through VC＋＋. STL files that exported from Pro/ Engineering and UG have been used to verify that the developed system is conducive to the subsequent disposal for STL model.
