VRML files can describe a scenegraph a bit similar to the internal
representation used by OpenSG and the loader tries to recreate an
equivalent OpenSG scenegraph when reading a VRML file.
So the first thing you need to do is find all geometries in your
scenegraph (take a look at Examples/Simple/10loading.cpp to see how the
traverse() function can be used).
When you've found a geometry you can use the TriangleIterator
(Geometry::beginTrianles(), Geometry::endTriangles()) to iterate over
all triangles and get the vertices/normales at the corners.
Ask if you need more details on any of these steps.
Cheers,
Carsten
