| 摘 要： | 皮肤变形是虚拟人合成研究领域的重要研究方向之一。交叉截面皮肤变形方法由于具有较好的实时性和逼真性在实时虚拟人应用环境中被广泛采用。但是这种方法要求虚拟人皮肤网格按照规则的交叉截面轮廓的方式组织，难以表达更丰富和精细的皮肤变形特征。基于此，本文提出了基于广义交叉截面的皮肤变形方法。该方法既具有速度快、操作简单、占用存储空间小的优点，同时又克服了交叉截面方法在皮肤网格组织方式方面的局限性，可以驱动任意皮肤网格组织方式的虚拟人表面模型，获得非常逼真的皮肤变形效果。

| Abstract: | Skin deformation is one of the most important problems in virtual human modeling. Firstly, a method based on cross-sectional contour is introduced in this paper,and then a new approach for skin deformation based on general- ized cross-sectional contour is presented. This approach inherits the merits of cross-sectional contour deformation which is simple,fast and space compressed. Moreover,it can drive arbitrary skin griddings and flexibly adjust the level of detail. Consequently, it can achieve better deformation result. |
