PRT (Precomputed Radiance Transfer )

Rendering technique designed to optimize the real-time rendering of a 3D scene by pre-calculating interactions.

HDR (High Dynamic Range )

A rendering technique that produces a wider dynamic range in a digital image to approximate what is perceived by the human eye in the real world.

PVS (Potential Visible Set )

Rendering technique that speeds up real-time rendering of a 3D scene by pre-calculating potentially visible areas.
