Thanks!

Hmm. I really don't know where to start after the SAH cost model of
kd-tree is finished. Most likely I'll spend some time refining the code
and making it more polished etc.

But I'll have to think about the material interface a bit more. Now I
have simple reflections and refractions which are not physically correct
and look unrealistic. Real reflections are angle dependent. A glass ball
reflects more at low angle than when looking form surface normal
direction. This has to be implemented properly.

I want to have Fresnel (or some good approximation like Shlick's
approximation). We'll see :D
