DMorph [image metamorphosis]

Image morphing is an artist-driven process. A creative human being looks at the images (or sequences) to be bridged and determines a way to make the changes that will be pleasing to the viewer and harmonious with the piece. To help these artists, I´ve developed a technique for automatically and smoothly turning one convex 3D shape into another. Like any automatic morph method, this technique should be viewed as a tool and not a self-guided process. DMorph has pros and cons. On the pro side, it is satisfyingly simple and robust and easy to program. It doesn´t place any constraints on the two objects being interpolated except that they´re convex. One object can be a 200-sided cone where 200 polygons all share a single vertex, and the other object a baseball, and the algorithm doesn´t care. There´s no feature matching, automatic or otherwise. The transformations are smooth, and the blending looks nice. On the con side, the program is limited to convex objects.
