【Abstract】 In this paper,frame coherence in real-time visual simulation is analyzed and an improved depth-sort algorithm is presented to increase the efficiency of hidden surface removal algorithm which is key to 3D image real-time generation.The performance comparison between simple sort and the improved sort is given.While the results of applications to different viewpoint movements are analyzed. A real-time visual simulation example with the improved algorithm is realized on PC.The results show that it has better real-time property and reality.更多还原
