In this paper we proposed an algorithm for blending between two given key polygonal shapes. Generally speaking, 2-D shape blending requires two mainsteps : one is vertices correspondence and the other is shape interpolation. Some approaches use matrix interpolation which sometimes causes shrinkages and kinks because a transformation common to all vertices may not exist. Other methods try to interpolate the length of edges and the angles formed by two adjacent edges[1]. This article makes an attempt based on center of mass to generate in-betweens more fast.
