An Integrated System for Modeling, Animating and Rendering Hair

There are basically four problems to solve in order to produce realistic animated synthetic actors with hair: hair modeling and creation, hair motion, collision detection and hair rendering. This paper describes a complete methodology to solve these basic four problems. We present how hair styles may be designed with our Hair Styler module. Then we survey the animation model and emphasize a method of collision processing. Finally, we explain how hair may be rendered using an extension of a standard ray‐tracing program. We also show applications of our synthetic actors with various hair styles and different styles of mustaches and beards.
