摘要
以球面三角网格为研究对象,通过对三角网格进行拓扑优化和对顶点进行几何位置调整,实现了网格的质量优化。首先给出了球面三角网格顶点度的理想值,通过调整网格顶点的度使其达到这一理想值而实现了拓扑优化;然后使用离散点光滑插值(DSI)方法实现了对网格顶点的几何位置调整。最后对算法进行了验证。
The algorithm of sphere triangle mesh optimization is provided by using topological clean-up and optimizing situation of the triangle vertices. An ideal vertex degree of sphere triangle mesh is given out at first, and then the topological clean-up is completed by adjusting the degree of each triangle vertex to this ideal degree. The situation optimization of triangle vertices is based on the discrete smooth interpolation （DSI）. Experiments show that the sphere triangle mesh can be improved well using this algorithm.
