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.

If all light sources are fixed in place, the radiance from any given light source in an area can be calculated ahead of time, for the entire geometric area it reaches. This is stored along with the other data for that area, such that when participants run through multiple lightsources, the precomputed data for that area can be quickly combined and calculated.

Raw Speed
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.

Wireless Data Swifter than Wired Data
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.
