Spherical Surface Projection Subdivided by Equilateral Polygon and Its Application
Hua Li · Jisuanji gongcheng · 2007
This paper proposes the method of using equilateral polygon to subdivide the surrounded spherical surface,so as to obtain the projection point and get the two-dimensional projections of 3D models.This method can gain even projection point,and carry on the encryption process to the specific region according to the 3D model’s characteristic,so as to gain more two-dimensional projections information.The method proposed in this paper has already applied in the 3D model recognition and 3D motion recognition work,and obtained good result.
