Using a paint program, a ray tracer and canned graphics provided with this manual and software, the user can learn to make an interactive 3-D virtual reality stereo walkthrough that is suitable for teaching 3-D game programming concepts. The guide contains lists of Internet sites, picture galleries, and World Wide Web pages presenting stereogram applications and technologies. It demonstrates how to take any bit-map image file, filter it, and convert it to a stereogram file. Non-technical coverage of the history and science of stereograms, Anaglyph, SIRDS (random-dot stereograms), and SIS (repeating-pattern. background stereograms) technologies are all discussed.
