Abstract
The term “virtual camera” is well-known in Computer Graphics. But, it usually represents a mere abstraction for labelling the projection mechanism from 3D to 2D. We believe, on the other hand, that a virtual camera should be a software entity that can be manipulated in the same way as cameramen manipulate real cameras. First, we present a integrated camera model which includes not only typical characteristics like the eye, interest point, zoom and spin but also other functions which we consider to be part of the camera definition like viewports and clippings. Then we introduce a model of a virtual movie-camera. Typical effects used by cameramen are described using this model — such as panning, tilting, tracking, zooming and spinning. The use of a stereoscopic virtual camera is also discussed. The second part of the paper presents the use of several virtual movie-cameras for special effects like wipe effects.
