摘　　要：多分辨率模型常常消耗很大的储藏空间,从CPU到图形系统的传输是模型绘制的瓶颈问题。给出了一种多分辨率模型表示和一种绘制单元,能够应用于模型的存储阶段和绘制阶段,以降低模型的存储量和绘制传输量,实验结果验证了提出的方法。A multi-resolution model often costs more storage space, and its communications from the CPU to the graphics system is the bottleneck of the visualization process. A multi-resolution mesh and a primitive were proposed. The primitive was used both in the storage stage and in the rendering stage, for decreasing the storage size of model and the transmission amount of vertices to the graphics system. The efficiency was measured by means of tests and results compared with the previous, obtaining better space cost and transmission cost.
