The cornell box comparision - original rendering on the left, the new radiosity processor on the right. I didn't bother to convert the actual data values from wavelenghts (in nm) to RGB values, so I just guessed at them. That accounts for the slight color shading differences (the front of the smaller box is brighter on the image on the right.) Also, note the use of lightmaps in the new one.
The unique thing about this shot, is that none of the light from this shot is direct light. The light sources are completely hidden behind the two ledges near the ceiling. Even with this indirect illumination, you can still see distinct changes in light (the soft shadows of the ledges from the initial bounce of light off of the ceiling) and the darkness behind the box in the corner.
An elongated light source. The lightsource is triangular. Because of this, one end of the lightsource emits less energy than the other. This, in turn, causes the far side of the soft shadow (under the hovering cylinder) to be softer than the other.
A simple test with pretty colors, marking "Disney was here." :)
Blending direct illumination (the white light direcly illuminating the scene) with the blue indirect light. Of course, the white light also gets bounced around, but there's much less of it than there is of the blue light.
Note the way the shadows fade nearly completely away as they reach the center of the structure's shadow on the ceiling.
The effects of a very long area lightsource. Note the drastically soft shadow of the box, and the sharp fall-off of the shadow from the table onto the floor as it softens almost immediately behind the table.
Another patented "Disney test". A few interesting things to note about this shot. There are three light sources hidden behind the right-hand-side wall. The green light is just behind the wall, directly aligned with the short box. Note how the light reflects off the face of the box (hidden) back onto the wall directly in front of the box. From there, that light then scatters into the entire room, casting a shadow of the box onto the ceiling. Note, however that the ceiling has TWO shadows of the green box on it. The first shadow is the box casting a shadow from the light source itself, and the second shadow is from the box casting a shadow from the reflected light.
Disney strikes again.
A rather boring test showing color bleeding of the red door onto the ceiling.

Non-filtered lightmaps with perfect anti-aliasing.
