摘　　要：动态可展曲面是采用哈密尔顿原理的一类新型动态模型。详细论述了这类动态模型的数值计算引擎。大量实验结果表明:(1)光滑和褶皱的可展曲面都可用动态网格模拟;(2)传统的挑战性问题如纸张褶皱仿真和塑性服装建模等都可用动态网格以稳定、快速的方式进行计算。Dynamic developable mesh is a new dynamic model which utilizes Hamilton principle. The authors present the full implementation details of this promising dynamic framework with a stable numerical engine. Experimental results are presented,showing that (1)both smooth and buckled developable surfaces can be modeled by the framework in a consistent way;(2)challenging problems such as crumpled paper simulation and plastic cloth modeling are solved in an efficient and distinct way with desired speed and stability.
