【摘要】 首先用Bloomenthal的多边形化算法生成一个粗糙的初始网格 ;然后在初始网格上分布若干个新顶点 ,新顶点可以均匀分布 ,也可以按曲率分布 ;再把初始网格上的老顶点和新顶点连接起来 ,生成一个中间网格 ,从中间网格上删除初始网格上的老顶点 ,得到重新多边形化的网格 ;最后细分这个网格 实验结果表明 :该算法可以生成近似等边的、大小由曲率指导的三角网格更多还原

【Abstract】 At first Bloomenthal’s Polygonizer is used to get a coarse initial mesh. Then some new points are added to the initial mesh, either uniformly or according to surface curvature, and are connected with old vertices of the original model to form an intermediate mesh. After removing most of the original vertices and retiling the mesh, a subdivision scheme is applied to improve the over all mesh quality. Experiments show our method produces a mesh of close-to-equilateral triangles with sizes dependent on the local surface curvature.更多还原
