Real-time controlled metamorphosis of animated meshes using polygonal-functional hybrids

Abstract

Polygonal models are widely used in computer animation. Static polygonal models are commonly animated using an underlying skeleton controlling the deformation of the mesh. This technique, known as skeletal animation, allows the artist to produce complex animation sequences in a relatively easy way. However, performing complex transitions between arbitrary animated meshes remains a challenging problem. There is a set of established techniques to perform metamorphosis (3D morphing) between static 3D meshes [Lazarus and Verroust 1998], but most of these can not be easily applied to animated meshes. The approach presented in this poster allows us to produce with great ease metamorphosing transitions between animated meshes of arbitrary topology using polygonal-functional hybrids [Kravtsov et al. 2010a]. Our technique uses the meshes of the objects as well as their skeleton animations. As a result we are able to generate metamorphosis animations of time-varying meshes of arbitrary topologies in near real-time.
