| 摘 要： | 传统的骨骼驱动蒙皮变形技术(LBS)在大转角的关节处会发生严重的“塌陷现象”,对此在分析了LBS缺陷的基础上提出了辅助骨骼驱动的改进蒙皮变形技术。该技术在大变形的关节处添加辅助骨骼,通过辅助骨骼的小角度旋转来代替单根骨骼的大角度旋转。实验表明辅助骨骼不仅能够有效地克服LBS的缺陷,而且能够充分利用LBS的优点。

| Abstract: | A new technology to skin deformation is presented in this paper.When linear blending skinning(LBS) is utilized to skeletal animation,an undesirable collapsing effect takes place to joints with large spin.The essence of collapsing is discussed,and auxiliary bones are attached to joints working badly.Practice proves this method feasible,because the effect of several auxiliary bones with smaller spin equals to that of a single bigger bone with larger spin. |
