that is hopefully only a cut&paste bug, you load to nodeptr
'cone' and but retrieve the geometry core from 'node'. BTW
Also I would use dynamic_cast<Geometry *>(node->getCore());
The hard C-Style cast will convert everything to a geometry pointer,
not just geometries. But as you loops below don't explode it seems
the cast does not go to wrong.
The other thing to try is to use:
NodeRefPtr cone = SceneFileHandler::the()->read(image, NULL);
in order to disable any default graphOp.

No, except for the above it looks ok. Could you send me the off file
too ?
