改进的骨骼蒙皮算法模拟皮肤变形

SKIN DEFORMATION SIMULATED WITH IMPROVED SMOOTH SKINNING ALGORITHM

骨骼蒙皮算法以其速度快等优点在角色人物变形动画中始终是使用最为广泛的皮肤变形算法。针对骨骼蒙皮算法所产生的"塌陷"、"裹糖纸"等问题,在基于拉伸蒙皮算法的基础上,提出了一种向皮肤可变区域中增加辅助节点的改进的蒙皮变形技术。实验结果显示,该方法能够有效地消除骨骼蒙皮技术中存在的"裹糖纸效应"缺陷,真实感效果明显增加。

Smooth skinning is always a most widely used method of skin deformation with the advantage of a faster algorithm for the animation of deformable human and creature characters. However it suffers from a number of problems, such as the collapsing elbow and candywrapper effect. The paper proposes a new skinning deformation technology that it increases the auxiliary nodes in the skin variable regions based on the stretch smooth skinning algorithm. The experiment shows that the method can banish ＂candy-wrapper effect＂ defects, and the realistic effect is significantly increased.
