To load VRML, instantiate a browser and use browser::load_url. You can
then access the scene root nodes via browser::root_nodes. Getting the
data you want is then just a matter of traversing the node tree. The
easiest way to do that is with a node_traverser. You use the
node_traverser by inheriting it and overriding its virtual on_entering
and/or on_leaving functions.

If you haven't found it already, API documentation is online at
<http://openvrml.org/doc/index>.

I hope this helps get you started. Feel free to ask more questions as
you get into it.
