In this paper we proposed a method for two dimension polygonal shape blending. The original Cartesian coordinates representation of polygon are converted to a new representation based on centroid, which can efficiently express the relations between vertices when blending two key polygons. In order to improve the results of blending, polygons are correspondingly decomposited into several sub-polygons. Main frame is formed by connecting orderly the centroids of each sub-polygon. Therefore, interpolations of main frame polygons and sub-polygons can reflect the overall interpolation in detail. Tests suggest that it work well enough and more smooth for most of realistic cases.
