Abstract

The present invention provides a technique for translating facial animation values to head mesh positions for rendering facial features of an animated avatar. In the method, an animation vector of dimension Na is provided. Na is the number of facial animation values in the animation vector. A mapping algorithm F is applied to the animation vector to generate a target mix vector of dimension M. M is the number of targets associated with the head mesh positions. The head mesh positions are deformed based on the target mix vector.
