A SkyBox class is used to render a sky in the scene. It's always considered static and 'at infinity', and as such it's always centered at the camera's position and sized to exactly fit within the camera's frustum, ensuring the sky box is always as large as possible without being clipped.

Method detail
createEntityPartitionNode()method
protected override function createEntityPartitionNode():EntityNode

Factory method that returns the current partition node. Needs to be overridden by concrete subclasses such as Mesh to return the correct concrete subtype of EntityPartition3DNode (for Mesh = MeshPartition3DNode, most IRenderables (particles fe) would return RenderablePartition3DNode, I suppose)

pushModelViewProjection()method 
public override function pushModelViewProjection(camera:Camera3D):void

Updates the model-view-projection (MVP) matrix used to transform from model to homogeneous projection space and places it on the stack. The stack allows nested rendering while keeping the MVP intact.

Parameters
camera:Camera3D — The camera which will perform the view transformation and projection.
updateBounds()method 
protected override function updateBounds():void

Updates the bounding volume for the object. Overriding methods need to set invalid flag to false!
