摘要 提出了基于单位外法向矢量空间的分层表面网格分割算法 ,通过将任意表面映射到单位矢量空间即单位球面上 ,以单位球面划分作为模板应用到任意表面分割 .通过划分 ,为三维表面网格建立了自然的区域面片分层表示 .实验表明 ,新算法不仅计算速度快 。 A hierarchical segmentation algorithm based on vector space was presented. It firstly maps the arbitrary surfaces into a unit vector space, which is isomorphic to the unit spherical surface, and then partitions them by the templet of partitioning unit spherical surface. It intuitively produces a hierarchical patch representation of 3D mesh surfaces. The experiments illustrate the new algorithm is fast and effective.
