摘　　要：针对现有算法存在的问题,提出一种基于能量模型的自由曲面展开改进算法.算法的改进主要是对时间步长的调整.通过调整时间步长,避免展开过程中发散现象,同时也有效地提高曲面展开的精度,较好地解决展开过程中因迭代次数过多而引起的振荡现象,提高曲面展开的质量.算例结果表明,算法是有效的,可以满足实时交互设计的要求.In allusion to occurring problems of existing algorithms,an improved algorithm of surface flattening based on energy-model is presented.The improved algorithm is mainly to adjust time-step to avoid divergent phenomenon in the course of flattening,at the same time enhance the quality of the flattened surface,and better eliminate oscillating phenomena caused by too many iterative numbers.The results of case study have shown that the improved algorithm is effective,and can conform to the requirement of real-time and interactive design.
