A new real-time sphere path tracer (CUDA and OpenCL)

Real-time path tracing of spheres on the GPU is hot it seems :-)

It looks very impressive and pretty. The path tracer owes its speed to the fact that it is completely running on the GPU and to a custom precomputed hashing algorithm.

Tokaspt (by tbp), Sfera (by LuxRender's Dade), the WebGL path tracer (by Evan Wallace), ... the list of real-time GPU path tracers featuring dynamic scenes with spheres keeps growing.
