Hello Sajjad,
So far i have got from the forum Jean-Sébastien Guay did his Masters thesis
on that domain and it would be really nice
if he provide the link to the report, at least it would be a starting
point for me.
My Masters thesis was written in French unfortunately, and translating
it all would take too much time. Anyways, the subject was not really ray
tracing but an extension to PRT (Precomputed Radiance Transfer) to be
able to recompute shading interactively in dynamic scenes.
Ray tracing with OSG is actually pretty easy if you just want to
raytrace a picture of your scene, just get your viewer camera's
parameters, generate some rays and use the kdtree support in
LineSegmentIntersector to trace through the scene. Of course, if you
want to do global illumination or advanced effects then it's more
complicated, but there's been a lot written on those subjects, and it's
not OSG's main focus, so you're pretty much on your own...
Hope this helps,
J-S
