CINEMA: A System for Procedural Camera Movements

This paper presents a general system for camera movement upon which a wide variety of higher-level methods and applications can be built. In addition to the basic commands for camera placement, a key attribute of the CINEMA system is the ability to inquire information directly about the 3D world through which the camera is moving. With this information high-level procedures can be written that closely correspond to more natural camera specifications. Examples of some high-level procedures are presented. In addition, methods for overcoming deficiencies of this procedural approach are proposed.
