Intel's LFM? You must have heard of it. It's gonna revolutionise realtime 3D graphics in games and serious applications too. Its a load of cool routines highly optimised for luminescence and stuff.
This method approximates the radiance data by partitioning it over elementary surface primitives and decomposing each part into a small set of lower-dimensional discrete functions.
I hope that cleared everything up. If not they have got Pretty pictures too. Oh by the way LFM stands for Light Field Mapping. So no fiddling with oversized aquatic life is required, well not unless you REALLY want to.
