Graphics hardware has been developed with image production in mind, but current hardware can be exploited for much more general computation. This paper shows that graphics hardware can perform general calculations, which accelerate the rendering process much earlier than at the later image generation stages. An example is given of the real time calculation of refractive caustics.
