I seem to be getting an error on the dynamic_cast line:
undefined reference to 'typeinfo for txp::TXPNode'
Have you seen this before using this example?

Hopefully this will come through this time - I had to signup my new work
email to be able to send from here. Anyway, here's a snippet that
should work, or at least give you something to go on:
#include <TXPNode.h> // from OpenSceneGraph/src/osgPlugins/txp
...
osg::ref_ptr<osg::Node> loadedModel = osgDB::readNodeFile(filename);
txp::TXPNode* txpNode = dynamic_cast<txp::TXPNode*>(loadedModel.get());
if(txpNode)
{
txp::TXPArchive* txpArchive = txpNode->getArchive();
osg::BoundingBox extents;
double xOrigin, yOrigin;
txpArchive->getExtents(extents);
txpArchive->getOrigin(xOrigin, yOrigin);
// do something with the origin and extents
}
Other than that, scrounge around through the header files in
osgPlugins/txp for more info, esp. TXPNode.h, TXPArchive.h, and
trpage_geom.h (for the trpgHeader definition).
