More Irradiace Volume + Lazy Interrelection Grid Images

These images show the block moving closer and further away from the ceiling. Notice that I use sharp shadows, not soft shadows here, since the soft shadow hack in the RTRT breaks as the rectangle approaches the ceiling (and the light).

Note that NO interpolation is used with the lazy grid, so as the block aproaches the ceiling, you get fairly badly pixelated color on the ceiling. Also, the interreflection color is a bit too bright (compared to the pathtraced images) as the block approaches the ceiling.

Framerates on these images are a little over 1 fps on 8 processors (degrading, as you can see, when snapshot is used :-))
