An Extended Camera Model for Ray Tracing

Ray Tracing is a well established image generation method, producing photo realistic images. This is achieved by calculating the light distribution throughout the scene. The Calulation starts a ray from the eye and traces it, bouncing where neccessary, producing specular reflexions and the like. Energy is assumed to be radiated from point light sources, thus producing high lights and shadows on the objects.

The usual way to do this is to take a simple camera with a standard lense form. We took a more general concept to describe extended cameras and lenses, which could produce arbitrary distortions, using linear and non linear transformations as well. This transformations are used to describe the camera lens and the image plane.
