基于三角形折叠的网格简化与特征保持算法

Mesh Simplification and Features Preserving Algorithm Based on the Triangle Collapse

三角形折叠简化算法可以通过简单的运算就能识别出模型的三角形中的关键顶点,并在简化的同时可以较好的保持模型的外观。特征三角形保留的策略,可以正确识别并过滤模型的特征三角形,从而避免了因为特征三角形的丢失而导致模型外观的失真和变形。识别边界三角形的策略能有效地保持模型边界的完整性,避免了出现边界裂齿的情况。

Simplification of triangle collapse can recognize the key point of model triangle through simplification and algorithm, preserving the appearance at the same time. The preserving of feature triangle can help recognize and filtrate feature triangles of the model, so as not to cause the distortion of the appearance of model. Reorganization of the edge triangle can preserve the completeness of the edge of the model effectively and avoid the split in the edge.
