Detailed Description

a node within a VTK scene graph

This is the superclass for all nodes within a VTK scene graph. It contains the API for a node. It supports the essential operations such as graph creation, state storage and traversal. Child classes adapt this to VTK's major rendering classes. Grandchild classes adapt those to for APIs of different rendering libraries.
