针对目前对STL数据缺陷估计的不足，提出了一种STL模型的可视化算法．在分析STL数据格式的基础上，对有效数据进行过滤，获得三角面的法矢量及顶点坐标参数．采用顺序文件的方式利用外存储器存储标准数据，避免了因三角面过多而造成系统占用内存空间过大的问题．利用C＋＋和OpenGL实现了可视化算法，系统具有平移、缩放、旋转等功能．应用实例表明本算法可有效检测STL数据的缺陷，为相关工艺的优化过程提供可视化支持．

Aiming at the demerits of STL data, a visualization algorithm of STL model is presented. Valid data con- sisting the vertexes and normal vector of triangular facet were separated out from STL file. The sequential file was used to save the valid data, and to avoid excessive use of memory. The algorithm was developed through C ＋＋ and OpenGL, and the system has the functions such as translations, scales and rotations. The case studies show that the error of STL files can be detected and the optimization of process can be visual supported by the system.
