| 摘 要： | 在计算机辅助设计、虚拟现实、数字多媒体系统设计中,B样条曲线是一种进行几何形状设计和构建真实感图形的重要工具。曲线的光顺性对最终产品的外观质感有着直接影响。文章在前人研究的基础上,给出了一种基于能量的及动态权值光顺算法（DWEF）。DWEF在改进传统能量优化方程的基础上加入“运行时加权”的概念。应用DWEF使得系统能够智能地对不同曲线采取不同的光顺参数,以取得更好的光顺效果。

| Abstract: | In industry design,the B-spline curve is an important tool for shape design and data fitting. The quality of final product shape is determined directly by the fairness of the B-spline curve. This paper describes a new method named DWEF(Dynamic Weighting Energetic Fairing) for B-Spline curve fairing.The method adpots a run-time weighting mechanism which makes itself efficient for fairing curves that are averagely smooth.Experimental results are also revealed in this paper to prove the efficiency of the method. |
