Controlled metamorphosis of animated objects

Although many animation, deformation and metamorphosis techniques have been proposed, the simultaneous combination of those three transformations has never been addressed for three-dimensional objects so far. This paper presents a framework for controlling metamorphosis between two animated implicit models built from skeletal elements. It relies on the animated BlobTree model that encompasses the animation and metamorphosis in a unified and coherent fashion. Our method is general and supports a wide range of animation systems such as key-frames or physically based systems.
