Abstract: Improving the rendering performance is a basic problem for computer graphics system. In this paper, we are aiming to investigate the impact on the rendering performance of some geometry compression methods. These methods are devised to optimize the use of the vertex cache. We will study how they interact with the on-chip texture cache. Based on the study, one simple method of improving rendering by texture-map-based triangle strips is proposed to balance the use of the vertex and texture caches. We have conducted the experiments to show the effectiveness of this method.
