Ray tracing is a computer graphics technique which produces an image of a scene by tracing the paths taken by light rays through the scene.
Results can be impressive but the technique is computationally expensive.
As well as basic ray tracing details the book provides the reader with much of the background information necessary for image production and storage. This is commendable as such information never seems to be available in one volume and is often assumed by more general graphics books. However, advanced ray tracing techniques are not discussed in any detail. The files are compacted and must be extracted before use. Although the reader is expected to be a PC user, much of the information is generally applicable and DKBTrace has been ported to many platforms.
