Ray Tracing Basics

Dr. Steve Parker, who's academic team has done much to advance the field of ray tracing--specifically interactive ray tracing has allowed me host his lecture slides on my blog. Dr. Parker left the University of Utah earlier this year with Dr. Peter Shirley and several students to join nVidia in the hopes to produce high-quality, interactive ray tracing for consumers. Some have sourced Dr. Parker as writing the first "interactive" ray tracer, which he implemented years ago on some SGI computers.

These slides are taken from his CS 6620 - Introduction to Computer Graphics II course. It was basically all about writing fast and efficient ray tracers. The slides contain a lot of C++, but start with basic vector math. The slides have been compressed by me using Multivalent so they're quite a bit smaller than the originals.

The first lesson is a typical introduction to the course with pictures of ray-traced images and why ray tracing is useful. Those wishing to skip these details can probably jump into the second slide. They also include student project images including mine--the chess set. Most of these competition images lost a lot of quality for some reason--even uncompressed. You can see my image in an earlier post to see its original size and quality.

Also, if you use these slides, please keep the reference to Dr. Parker and his course.
