An Efficient Rendering Method of Object Representation Based on Spherical Coordinate System
Eun-Ho Han, Hyun-Ki Hong · Journal of Korea Game Society · 2008
This paper presents a novel rendering algorithm based on sperical coordinate representation of the object. The vertices of the object are transformed into the sperical coordinate system, and we construct additional maps: the centroid and index of the triangle, the memory access table. While OpenGL rendering pipeline touches all vertices of an object, the proposed method takes account of the only visible vertices by examining the visible triangles of the object. Simulation results demonstrated that the proposed method achieve an efficient rendering performace.
