Research on Accelerate Method of Ray Tracing

摘要：

　　Based on the analysis of the factors which affect the computing efficiency of the ray tracing method,an accelerate method of ray tracing method which can be used in open geographic environment was proposed.This method divided the whole terrain into small terrains,then chose the suit terrain which the ray emitted into after the analysis of ray features,so the number of intersection calculation between the ray and triangle faces which consist of the terrain is reduced from whole terrain scale to one smaller terrain scale,so the number of intersection calculation is reduced,therefore the speed of simulation and the efficiency of ray tracing is improved.Simulation results verify the correctness and validity of this method.
