Precomputed Radiance Transfer
Precomputed Radiance Transfer, or PRT, is a method of dealing with complex lighting, without causing bottlenecks in performance. It is most frequently used in gameworlds with level layouts pre-created. This method does not usually work well with highly dynamic environments.

Industry news, originally posted 23-02-2005. The human body is now a transmission medium for computer data. Just shake hands to transfer that file.
Using the current approach to data transfer the Internet is built on, full VR would never be possible. Just too many thousands of packets for different senses, all moving at once. You would literally come apart at the seams. Thankfully, there is another approach; Internet 2.
IMEC, a nanotechnology company out of Leuven, Belgium, has developed a new approach to neuroprosthetics, an electrode probe that is capable of two-way data transfer. It can read neighbouring electrical impulses, and at the same time, transmit new impulses back.
The raw speed communication is possible at on the internet is a linchpin of VR for social use. As the immersion level deepens, and more and more bodily senses are incorporated into the simulation, the demand for high speed data transfer escalates. This report looks at some of the recent attempts to squeeze faster and faster data transference from the internet infrastructure.
One of the real issues with wireless data transfer is the slow speed at which it transfers data. Near-future high-sensory-bandwidth systems such as virtual reality and simulated stimulation are even at this stage, pushing the limits of bluetooth or Wi-Fi. Anxious to download his wedding videos more quickly, a German researcher has created a 1GB/sec system, with the potential for wireless 10GB/sec.
