Documentation

EarthSky is a Group node which controls the clearing of the color and depth buffers at the start of each frame. The earth sky by default is empty and simply holds the clear color of the background. However, if the uses wants to add their own clearing of the color and depth buffers then the children can be added, and the background clear turned off. The EarthSky by default has StateSet attached to it which sets the default EarthSky bin number to -1, so that all drawables below it are placed in a separate bin from the rest of the scene graph, and are rendered prior to standard opaque and transparent drawables.
