| | | There's been a bit of a stir on the Internet lately due to AMD's recent Leo demo, which was recently revealed to be using a modern twist on Light Indexed Deferred Rendering. The idea of light indexed deferred has always been pretty appealing, since it gives you some of the advantages of deferred rendering (namely using the GPU to decide which lights affect each pixel) while still letting you use forward rendering to actually apply the lighting to each surface. | ||
