The Amusement Machine - Real Time Raytracing...test it now.
Interesting bit of news indeed, please try http://theamusementmachine.net/ . We are showing real-time ray-tracing on NVIDIA GPU's combined with rasterization(in some videos combined). There is also a beta demo you can download and try if you register. Quite a bit different from the classic spheres and refelections. Enjoy.
