细分曲面中裂缝处理的一种方法

A method of crack processing of subdivision surface

结合曲面在参数空间递归细分和沿曲面上曲线采样的方法,提出一种避免在曲面细分过程中产生裂缝的方法,基于三角面片边界的平坦性检测,提出了产生三角面片内部边界的四种可能性。应用这种算法细分曲面,能避免细分曲面产生裂缝。

Combines recursive simplicial subdivision of the domain and point sampling along curves on the surface,a new method of surface crack processing was provided. Discussed the four possibility of generating the internal edges of triangular meshes, based- on the flatness testing of each triangular mesh ＇ s edge. It can avoid generating cracks on subdivision surface.
