In this dissertation, the planar shape blending algorithm based on visual feature is proposed, and the 2D Character Animation Blending method based on this algorithm is presented, which can deal with shapes composed of several closed regions.

• 本文在分析和比较已有的二维多边形形体渐变算法的基础上,提出了基于视觉特征的平面形体的渐变方法,并在此基础上给出了一个2D角色动画变形方法,可以实现包含多区域的形体的变形。
