Also consider using the osg::TriangleIndexFunctor for iteratoring
through the drawables, it simplifies the job quite a bit. Have a
look at the src/osgUtil/IntersectVisitor.cpp for an example of both a
visitor and the functor being used in action.

The other option is to use a NodeVisitor to accumulate a list of
pointers to all the osg::Geometry drawables in the scenegraph that you get
from loading a .osg file. Take a look at 'FindNamedNodeVisitor' in
examples/osgsimulation/osgsimulation.cpp for an example of a simple node
visitor class.

is valid, how can I cast that pointer to a osg::Geometry*
safely?

I can’t find how to get the vertex buffer, triangle
data, stride, normals, etc… from an osgNode. I need to be able to do
this so I can pass this information to OSD or my own physics engine.
How can I do this?
