Detailed Description

A Group node for clearing the color and depth buffers.

Use setClearColor to change the clear color, and setRequiresClear to disable/enable the call clearing. You might want to disable clearing if you perform your clear by drawing fullscreen geometry. If you do this, add child nodes to perform such drawing. The default StateSet associated with this node places children in render bin -1 to ensure that children are rendered prior to the rest of the scene graph.
