【Abstract】 Based on the analysis of the current status of the real time volume rendering of 3D data sets,discusses emphatically the five measures to realize the real time volume rendering:the method to reduce dimension of sampling,the method of relativity in space,the method to skip the empty voxel,the method based on hardware and the method of parallel processing.Besides,this paper compares the characteristics of each algorithm.As a result,it points out the further studied direction of the real time volume rendering of 3D data sets.更多还原
