Nvidia have produced a proof-of-concept demo that shows how standard (albeit powerful and heavily tweaked) graphics processors can be used to render raytraced scenes in real time.

Raytracing is a method of generating a computer image by tracing a ray of light through an image plane. The whole process is similar to how light bounces off objects in nature, determining the color, sheen, luminosity, etc. Whereas other methods of creating graphics have to generate special effects, shadows, bloom,…
