Abstract
Preparing a facial mesh to be animated requires a laborious manual rigging process. The rig specifies how the input animation data deforms the surface and allows artists to manipulate a character. We present a method that automatically rigs a facial mesh based on Radial Basis Functions (RBF) and linear blend skinning approach. Our approach transfers the skinning parameters (feature points and their envelopes, ie. point-vertex weights), of a reference facial mesh (source) - already rigged - to the chosen facial mesh (target) by computing an automatic registration between the two meshes. There is no need to manually mark the correspondence between the source and target mesh. As a result, inexperienced artists can automatically rig facial meshes and start right away animating their 3D characters, driven for instance by motion capture data.
