| 摘 要： | 鉴于目前商用图形软件包对于复杂模型中三维实体集显示与选择的局限性，本文提出了一种新的判断点与面域从属关系的方法，此方法借鉴计算机图形学中扫描转换填充算法的射线法，并在此基础上对射线法进行扩充和完善，文章同时对三维复杂实体群的交互手段和技术进行了研究，在解决实际问题中取得了良好的效果。

| Abstract: | Among the commercial graphics packages of Computer Aided Design, there are some limitations about display and selection of complex 3D entities. In this paper, a new method which check relationship between point and region is proposed. It based on and improved on radial algorithm about scan-transition-fill in computer graphics. Paper study interactive techniques for complex 3-D multi-entities also. Experiment result at the end of the article verifies the effectiveness of presented approach. |
