Detailed Description

Stores a set of modes and attributes which respresent a set of OpenGL state. Notice that a StateSet contains just a subset of the whole OpenGL state.

In OSG, each Drawable and each Node has a reference to a StateSet. These StateSets can be shared between different Drawables and Nodes (that is, several Drawables and Nodes can reference the same StateSet). Indeed, this practice is recommended whenever possible, as this minimizes expensive state changes in the graphics pipeline.

Typically, users will set this to either StateSet::OPAQUE_BIN or StateSet::TRANSPARENT_BIN. Drawables in the opaque bin are sorted by their StateSet, so that the number of expensive changes in the OpenGL state is minimized. Drawables in the transparent bin are sorted by depth, so that objects farther from the viewer are rendered first (and hence alpha blending works nicely for translucent objects).
