/**
* A simple wireframe cube, comparing two functionally equivalent nodes: IndexedLineSet (per-vertex coloring) with LineSet (per-segment coloring). Keeping track of how each node "connects the dots" is simply a book-keeping problem.

This program uses the
X3D Java Scene Access Interface Library (X3DJSAIL).
It has been produced using the
X3dToJava.xslt
stylesheet
(version control)
which is used to create Java source code from an original .x3d model.
