GraphicBranch Class

A node in a scene graph. The branch itself is not renderable. Instead it contains a list of RenderGraphics, and a transform, symbology overrides, and clip volume which are to be applied when rendering them. Branches can be nested to build an arbitrarily-complex scene graph.

see RenderSystem.createBranch
