Animated Map for Radiosity and Caustic

I suggest canimated per-calculated map for radiosity and caustic.
The realtime RayTracing age is near,
when the game engine can render in raytracing they need also better light deep,and with the impossibility to realtime calculation of raytracing and caustic for the next 10 year,i suggest a simple trick for reach this goal.

Sure, but can’t you already do it with current opengl implementation, or is there something that needs to added into the api?


You can use 3D textures for canned animations with linear interpolation between “frames”. Or you can just use TexSubImage to update textures.
