摘　　要：针对薄壳变形问题,提出结合基于样例与基于物理的离散变形能量驱动薄壳变形的方法。利用拉普拉斯网格编辑方法构造样例模型,构造衡量模型变形的基于物理的离散变形能量模型,计算模型变形所需的离散变形能量,对离散变形能量进行插值并驱动模型变形。实验结果表明,该方法构造样例模型有效控制了模型的变形趋势,利用基于物理的离散变形能量衡量模型变形,使变形结果更真实,获得连续自然的变形序列。To simulate the deformation of thin shell,a technique combining the example model and physics-based discrete energy of deformation was proposed.The example model was determined using Laplace mesh editing method.The physics-based discrete energy model of deformation was constructed and physical energy required for deformation was calculated and interpolated to drive the model deformation.Experimental results show that constructing the example model can effectively control the deformation trend of the model and using physics-based discrete energy of deformation to measure the deformation of model can make deformation results more realistic and get the continuous and natural deformation sequences.
