Just a raytracing test from an OBJ file using the awesome RayTrace library( math.ucsd.edu/~sbuss/MathCG/RayTrace/ ).
I sort of messed up the model so that is why the edges of the O are a little funny.
The material is a glass like material.
The code compiled very nicely into OF - I need to explore to see what is possible, obviously it won't look as awesome as sunflow. But I think it has bump map support.
Loading more stuff…
Hmm…it looks like things are taking a while to load. Try again?
