A data structure for a multi-illumination model renderer

The rendering of realistic computer images is important for many scientific, technical and commercial and endeavors. Available literature provides the mathematical models to be utilized by a renderer. Lacking from the literature though are implementation details. This study examines some of the existing illumination and shading models and present a data structure and initial design for a multi-illumination model renderer. Keywords: light rays; ray tracing; computer graphics; computer generated images.
