A rendering state is a collection of state attributes, such as light sources, materials, textures, and display modes, turned on and off with glEnable () and glDisable (). When you set a specific state, it is valid until some other function changes it. The OpenGL pipeline supports a state stack to save and restore states at any time. The state machine provides the developer with full control over the current and stored states of the rendering. 3r31278.  3r31293. 3r31278.  3r31293. However, this approach is inconvenient when working with OSG. For this reason, the OpenGL state machine is encapsulated by the osg :: StateSet class, which takes over operations to work with the state stack and its installation in the process of traversing the scene graph. 3r31278.  3r31293. here .
