I confirm model_geode a not NULL,When i convert my model.osg-->model.IVE
return viewer->run() is OK. Why?

Hi YangXiao,
This is basic debugging... is model_geode a NULL??
Also why the word geode in the ptr, readNodeFile returns Node* not
Geode*. Most scene graphs will not have a Geode at the top of the
scene graph. Since you don't supply the offending code we can't
really guess at what mistakes you've actually made.
Robert.
