Performance Measurements
- Rayshade produces statistics for every image it generates (CPU time,
rays fired, cache efficiency)
- Rayshade does not run in real time, but is reasonable. Cover
image took 20 minutes to render at 256x256, textured heightfield in stereo
example took 4 minutes at 256x256 (with two directional light sources).
- You can tune performance for scenes with many objects by giving an
explicit grid structure
