The future in gaming graphics

Raytracing is something that many of the 3d and modeling afficionados will be intimately familiar with. Rather than just approximating things, raytracing involves physics calculations of each ray of light from a source through each volume of space, based on the volume's properties of refractivity, reflexivity, transparency, and other things. This technique is the proverbial 'holy grail' of graphics, as it is no longer 'guessing' - things become as real as you want to be, depending on how you control the properties of the textures.
