Questions tagged [deferred-rendering]
The name for a class of rendering technique where geometry and material properties are explicitly separated from the lighting computations. This is done by rendering the material properties of various objects into several buffers, and then using passes over those "g-buffers" to do lighting computations, a screen-full at a time. This technique uses lots of bandwidth, but can be a strong optimization in situations with lots of lights.
