This paper presents a method for the metamorphosis of genus-0 triangle meshes based on their intersection. It is an extension of our previous 2D algorithm [M´alkov´a; 2007]. Our algorithm is designed to simulate growing processes; therefore it is useful for morphing objects; where the user expects some parts of the latter object to grow out from the former one (e.g. a head with and without horns). The user can influence the algorithm’s behavior by changing the mutual position of the objects; while the results are easily predictable.
