带尖锐特征的自适应Loop细分算法

Adaptive Algorithm Using Loop Subdivision Scheme with Sharp Features

文章提出了一种带尖锐特征的自适应Loop细分算法,自适应过程由二面角的阈值来控制。该算法除能保持模型的尖锐特征外,还可以根据用户需求进行自适应细分,大幅度抑制细分过程中网格数量的快速增长,并能获得与原始算法光顺程度基本一致的曲面。

An adaptive refinement method based on Loop subdivision scheme is presented in the paper, Adaptation process is controlled by the dihedral angle value. This algorithm can hold sharp features well, and adopt adaptive subdivision according to users＇ requirement .Thus the adaptive refinement can remarkably decrease the number of meshes and keep the good fairness of Loop surfaces with fewer meshes.
