The paper "Accelerating path tracing by eye path reprojection" by Niklas Henrich et al., which I blogged about earlier is available from http://www.rendering.ovgu.de/publikationen.html. The algorithm achieves similar quality as regular path tracing in half the time and can easily be ported to the GPU. The authors also plan to incorporate their technique into a real-time raytracer.

Huh. From the scant preliminary information, I thought they were using random vertices as virtual point sources. Using onscreen bounces as free samples is much more interesting - even if it doesn't always add much light.
