Abstract: An input device for a computer graphics system provides a plurality of wheels that control movement of a virtual camera. The input device can be readily used by professional camerman without knowledge or training on CG animation software tools. The input device comprises a housing having at least one wheel operatively coupled to at least one outer surface of the housing. The at least one wheel has an axially coupled shaft that is driven rotationally by manipulation of the wheel. Circuitry contained within the housing and operatively coupled to the shaft generates a control signal corresponding to rotational motion of the at least one wheel. The control signal is thereby provided to the animation processor to control the virtual camera.

Abstract: A performance or show production system and method allows a performer to control and interact with an on-stage display or screen. The on-stage screen is used to create a virtual extension of the stage. Images displayed on the screen may include video playback and real-time generated, texture mapped graphics. The system includes a media production system for producing visual images, a display system for displaying the visual images, a tracking system for tracking the position of the performer on the stage and for producing a position indication, and a control system for controlling the production of visual images by the media system as a function of the position of the entertainer on the stage.
