When we visited Imagination Technologies at CES, they were showing off some intriguing hardware that augments their GPUs in order to accelerate ray-traced rendering. Ray tracing is a well-known and high-quality form of rendering that relies on the physical simulation of light rays bouncing around in a scene. Although it's been used in movies and in static scene creation, ray tracing has generally been too computationally intensive to be practical for real-time graphics and gaming. However, Imagination Tech is looking to bring ray-tracing to real-time graphics €”in the mobile GPU space, no less €”with its new family of Wizard GPUs.
