Generates a selection buffer object for a given camera. The selection buffer is used of entity selection. On setup, a unique color is assigned to each entity. Whenever a selection request is made, the selection buffer camera renders to a 1x1 sized offscreen buffer. The color value of that pixel gives the identity of the entity. More...
