Detailed Description

Class for generating materials for objects to render themselves in the merging step of deferred lighting.

This stage takes the LBuffer as an input and performs an extra geometry pass. It uses the material info from the geometry pass, and the light info from the LBuffer to recreate the Blinn-Phong lighting model. Alternatively, different lighting models can be recreated(like adding a fresnel term during merging).

Note

This does not support all the possible rendering techniques out there. In order to support more, either expand this class or make sure that objects that will not get treated correctly will not have materials generated for them.
