Ray Tracing Help

Hi, I want a good material for learning raytracing using opengl and glut.I also want to learn how to do global Illumination.Ex:Like ambient occlusion.

Here’s all you need:


OpenGL is a rendering API, and does not do ray tracing, nor does it do global illumination for you. For GI, you might want to use Jan’s tool there (google) and look into screen space ambient occlusion, which give a fairly good approximation in real time. Raytracing is often used to pre-compute light maps (irradiance maps), but is not really done in real time rendering. There have been some example of “real time” ray tracing running at say 4fps or so, which is really impressive, but not ready for prime time yet.

OpenGL doen’s do ray tracing, and is not a good way to start ray tracing with OpenGL(you need to know shaders, CUDA,…). Here is a good link for start ray tracing. It’s not old and teach you all the basics.


oops, I am a dummy :S…
Sorry, here si the link
