Modelling three dimensional animated, detailed, and emotional facial expressions

This paper presents methods for generating 3D facial expressions. Special pattern functions are created and employed to generate detailed, animated facial expressions. The created pattern functions include wrinkle patterns (forehead wrinkles, eye corner wrinkles, cheek wrinkles, and frown wrinkles), dimple pattern, and eye pouch effect pattern. A formula for generating realistic, animated teardrops is introduced. Methods for generating real-time vivid shedding tears is also shown. Test results show that these methods are robust, accurate, and consequently will advance 3D facial expressions and animations significantly.
