| 中文摘要: |
| 首先研究了传统的Loop细分曲面算法，通过分析发现随着细分次数的增多细分算法中三角形网格片数增长过快。针对这一问题提出一种自适应细分曲面算法。算法根据相邻两个三角形面上的法向量的夹角，判断细分网格中较为光滑和非光滑的区域。实验结果表明，算法提高了数据处理速度，并且模型简单易实现。 |
| 英文摘要: |
| Firstly, the traditional Loop subdivision surface algorithm is studied. The analysis show that the increase of the number of triangular mesh is growing too fast in the traditional Loop subdivision algorithm. Secondly, in order to solve this problem, an adaptive subdivision surface algorithm is given. This algorithm bases on the included angle of the two normal vector of the two adjacent triangles to judge the more smooth and nonsmooth area in subdivision grid, than subdivides the nonsmooth area only. Finally, the experimental results show that this algorithm improves the speed of subdivision processing, and the model is easy to implement. |
