Anyone know a good ray tracing tutorial? I did a quick google search but didn''t come up with anything great, so I figured someone here has used ray trace rendering with OpenGL. Thanks.

opengl cannot raytrace directly. its normally done in software. and google returns actually quite a lot of good stuff..

I know OpenGL doesn''t do raytracing. I was looking more for the methodology for ray tracing, and then using OpenGL to do the rendering. I''ll keep looking.
Thanks.

The sites that got me started were PolyGone at http://polygone.flipcode.com/ and Fuzzy Photon at http://fuzzyphoton.tripod.com/.

You can download a raytracer in C++ (for VC++ 6.0) from my site. It''s certainly one of the most rewarding projects I''ve done, raytracing is a great technique and the feeling of knowing that every step of the image generation is yours is wonderful.

Good luck!
