3D Lighting Simulation

Lighting simulations produced with Radiance, a highly accurate global illumination renderer.

These models are based on a sunny August 30 at 2:30pm PST 44.8 degrees north latitude. Walls and floors have a 50% grey value. White walls would bounce the light further around in the house. Click on thumbnail for (much) larger jpegs.

The bottom image is a false color rendering showing the lighting values. I'm learning this stuff myself, so for an explanation of nits, check out this PDF.
