We have presented techniques for computing shape transitions between polygonal 3D objects. These techniques have proven to be fast and intuitive methods for 3D polygon morphing. Our technique does not require too much user interaction time in contrast to other previous wok [3,5]. Furthermore, the proposed embedding and merging methods perform well to be comparable to or even much better than the-state-of-art. In the evaluated examples, both are computed very fast (less than 1 or 2 seconds). A number of researches can be done in near future. For example, we can replace the linear interpolation with other alternative to avoid self-intersection. The merged embedding usually has about 2 to 5 times as many triangles and vertices as the input models. We plan to design a new method of 3D morphing without the requirement of the embedding merging. The morphing shapes can automatically adjust the number of triangles and vertices in need.
