First, the input model is embedded into a coarse tetrahedral control mesh, and the modified barycentric coordinates are employed to establish their relationship. Then according to users editing, the control mesh is deformed by solving a quadric nonlinear energy minimization problem, and the deformation is passed to the embedded model by interpolation.

首先将输入模型嵌入到一个稀疏的四面体控制网格中，并且通过一种改进的重心坐标来建立两者的对应关系；然后通过用户的交互，对控制网格建立一个二次非线性能量函数对其进行变形，而输入模型的变形结果则可以通过插值来直接获得。

Firstly, a spherical mesh with regular subdivision connectivity is constructed to partition the spherical domain into some small regions. Then the region, which contains the query point p, is found according to the position of p and selected as the search area for locating p. During the point location, the barycentric coordinates are used to extract local heuristic information about the location of p so as to find the shortest path from the start triangle to the target one containing p.

通过构造规则子分网格将原始球面网格区域划分成若干具有子分层次关系的查询小块；在进行查询前，根据查询点p的位置找到它所在的小块作为搜索区域，从而极大地缩小了查询范围；在查询过程中，根据重心坐标所包含的启发信息，选择一条从初始搜索三角形到目标三角形的最短查询路径。
