摘　　要：借助柳编工艺品三维仿真系统,设计者能够快速、方便地设计出各种样式的产品,但已有仿真系统的图形渲染速度比较慢,在现实中没能达到应有的实用价值.针对这一问题,结合Bèzier曲线曲面细分方面的知识,给出了一种快速图形渲染算法.数值实验结果表明,采用新算法的仿真系统和已有仿真系统相比具有渲染速度快、占用资源少、易于后期编辑等优点,进一步提高了仿真系统的实用性.With 3-D model simulation system of willow arts and crafts, one can design a rich variety of products quickly and conveniently. However, the existing simulation system has a relatively slow rendering speed. To overcome this problem, an effective rendering algorithm based on subdivision of Bezier curve and surface is presented in this paper. Numerical results demonstrate that the new system has the high rendering speed, less occupying resources, easy postediting and so on compared with the old one. Thus the practicality of this simulation system is further improved.
