Abstract:
This paper presents an algorithmfor determiningthe paths along which
corresponding vertices travel in a 2–D shape blending. Rather than
considering the vertex paths explicitly, the algorithm defines the intermediate shapes by interpolating the intrinsic definitions of the initial
and final shapes. The algorithm produces shape blends which generally are more satisfactory than those produced using linear or cubic
curve paths. Particularly, the algorithm can avoid the shrinkage that
normally occurs when rotating rigid bodies are linearly blended, and
avoids kinks in the blend when there were none in the key polygons.
