OpenGLContext.scenegraph

Retained-mode object hierarchy based (loosely) on VRML 97 nodes

This package provides "retained-mode" objects which can be easily rendered within OpenGLContext Contexts.

The implementations of the objects are fairly straightforward with the idea that users will browse the source of the objects to see how they can implement similar functionality in their own systems. There is little optimization in the nodes provided.

Note that much of the work of rendering is accomplished by the rendervisitor module, rather than individual nodes. The node- classes merely have the node-specific customisations needed to support their individualised operation.
