Environment Spherical Harmonics
This demo scene shows Environment Lighting using Spherical Harmonics generated by Turtle 4. You can watch it even if you don't have Maya.
With Turtle 4 you can precompute all light cast from the environment (direct and indirect) as Spherical Harmonics. This can be used for extremely efficient relighting of geometry moving through the scene.
You can download the demo here. Don't forget to look over the read me before watching the scene.
