After establishing the topology relationship of scattered points, the mesh surface model of point data is reconstructed by triangulation.
建立了散乱点云数据之间的拓扑信息，对点云数据进行三角剖分重构网格曲面模型。

Based on the idea of constrained triangulation, a practical criterion and corresponding algorithm to determine the point inclusion of polygon are put forward.
