| Abstract: | In this paper,a definition of three dimensional convex hull of a set of spatial pointsis presented. The partitioning index method based on octree for spatial points is proposed. Analgorithm for three dimensional convex hull creation is developed and some tests are made toconfirm the algorithm. |
