Using virtual reality techniques in the animation process,” in Virtual Reality Systems

This paper tries to find the various functions involved in an animation system and how virtual reality techniques and multimedia input could play a role. A classification of VR-based methods is proposed: real-time rotoscopy methods, real-time direct metaphors and real-time recognition-based metaphors. Several examples are presented: 3D shape creation, camera motion, body motion control, hand animation, facial animation. The hardware and software architecture of our animation system is also described. 1
