编撰了有关平面三角学和球面三角学的著作,解决了球面三角学中的若干难题,并首先提出引进辅助角的方法解三角形。

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。

Then we re-sampling all signals defined on the surface of the original triangle mesh at the vertices of the spherical subdivision mesh and get a set of discrete geometry signals with subdivision topology which can be compressed by using spherical wavelet.

于是,在参数域内位于细分网格顶点处对定义在参数网格表面上的各种几何信号进行重采样,可得到新的具有细分结构的几何信号近似表示原始几何信号,以此满足球面细分小波对处理对象的细分结构要求,从而使得用球面细分小波对几何信号进行压缩得以实现。
