/**
*
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.
Related links: LineSetComparison.java source, LineSetComparison catalog page, X3D Resources, X3D Scene Authoring Hints, and X3D Tooltips.
This program uses the
X3D Java Scene Access Interface Library (X3DJSAIL).
It has been produced using the
X3dToJava.xslt
stylesheet to create Java source code from an .x3d
model.
