Earlier yesterday at an NVIDIA meeting , NVIDIA claimed that thay would be announcing the acquisition of a ray reacing software company called RayScale . RayScale was a startup based out of the University of Utah and has built a hybrid renderer that merges traditional rasterization and ray tracing techniques .

Although the acquisition is now cut and dried , there will be some time for us to see these techniques in games – both the software and hardware need time to mature and be optimized ; and both the companies need time for the superior use of GPU in ray tracing .

The following is some information about the ray tracing technique :

• Ray tracing (physics)
• Ray tracing (graphics)
