Abstract

Two categories of methods for generating detailed animated facial expressions are presented. The first category is to apply pattern functions to the surface of a facial model. The pattern functions allow a user to directly manipulate them and see immediate results, and allow expressive features to be applied to any existing animation or model. The location and style of an expressive feature can be specified, thus allowing the detailed facial expressions to be modeled as desired. The technique can also be applied to a variety of CG human body skins and animal faces. The second category is to create tears, which combined with facial models can generate detailed, animated, emotional expressions. The category contains two unique methods for generating realistic, animated tears. One method is for generating teardrops, which continually change shapes while dripping down the face. The other is for generating shedding tears, which seamlessly connect with the skin as they flow along the surface of the face. The method provides real-time, vivid simulation of tears rolling down the face. These methods both broaden CG and increase the realism of facial expressions. The methods can also be applied to CG human body skins and other surfaces to simulate flowing water.
