GeForce GTX 980 WhitepaperMAXWELL: ENABLING THE NEXTFRONTIER IN PC GRAPHICS13Maxwell: Enabling The Next Frontier in PC GraphicsCorrect modelling of lighting is the most computationally difficult problem in graphics, and withMaxwell, our objective was to make an enormous leap forward in the capability of the GPU to performnear-photo-real lighting calculations in real time.In the real world, all objects are lit by a combination of direct light (photons that travel directly from alight source to illuminate an object) and indirect light (photons that travel from the light source, hit oneobject and bounce off of it and then hit a second object, thus indirectly illuminating that object). “Globalillumination” (GI) is a term for lighting systems that model this effect. Without indirect lighting, scenescan look harsh and artificial. However, while light received directly is fairly simple to compute, indirectlighting computations are highly complex and computationally heavy.
