A simple approach to 3D object metamorphosis

This paper presents a technique for smoothly blending some special categories of three-dimensional polygonal objects. Polygon blending is usually considered a two-part process: generating vertex correspondences and interpolating between corresponding vertices to create the intermediate polygons. This paper emphasises on the problem of automatic vertex correspondence determination. The proposed algorithm is based on a simple heuristic method for the metamorphosis of closed planar contours.
