摘　　要：STL格式产品模型(简称STL模型)是由成千上万的相邻三角面片组成。由于组成STL模型的面片复杂而繁多(通常有上万个面片),拾取表面上某些点往往需要较长时间,给用户操作模型时带来很多不便。针对这一问题,作者对STL模型表面点的快速拾取原理进行研究,提出快速拾取算法,并给出了算法示例和结果。The STL Format Product Models (STL Models for short) comprise thousands of adjacent triangular faces. As a result of the complexity and variety of STL triangular faces, the operation of surface points pick-up needs a relatively long time. This causes great inconvenience for users to manipulate STL Models. To solve this problem, this paper analyzes the surface points quick pick-up principles of STL models, comes up with a points quick pick-up algorithm, and gives an algorithm application and it’s results.
