History of ray tracing and World of Spheres

I trace the root of world of spheres up to the wonderful Kevin Beason's SmallPT. Thierry Berger-Perrin ported SmallPT to CUDA with Tokaspt.
I wrote SmallPT GPU and SmallPT GPU2: an OpenCL version of SmallPT, as soon as the ATI OpenCL SDK was released.
Ray Tracey's Tokap has shown that real-time ray tracing is a viable option for games and world of spheres.
I hope Sfera will be another enjoyable chapter in the path of world of spheres !
