[osg-users] Processing vertices in a subtree

[Argentieri, John-P63223]

Robert,

I've tried to write a NodeVisitor to grab all the vertices in a subtree.
I'm trying to push those vertices into DelaunayTriangulator. The problem
is that my NodeVisitor ends up seeing each vertex like 5 times in the
subtree. Is there a way to get a set of all vertices with no repeats at
the Geode/Drawable/Geometry/Primitive level?

Thanks,
John Argentieri
