Beyond Viewpoint: An X3D Camera Node

This paper describes four candidate X3D extension nodes: Camera, Shot, Movement and OfflineRendering. An X3D lexicon for camera movements is defined so that individuals directing virtual cameras in X3D can directly apply terms that film directors and cinematographers understand. This approach greatly simplifies the technical tasks involved in creating precise camera animations and setting up still images for digital photography. Further, candidate methods are examined for implementing Depth of Field for focus control. Moving beyond the typical clumsiness of Viewpoint control can enable authors to create compelling still and moving images from X3D scenes.
