Hi Philip, I will have a look into this, but can't do it immediately.
Could you send the whole modified file that you have so I can compare against. Robert. On 1/12/07, Philip Lowman <[EMAIL PROTECTED]> wrote:

Robert, et. al., Can someone on this list confirm that the _activePagedLODList is indeed the list of PagedLOD nodes that are completely outside of their PagedLOD ranges (by moving the eyepoint very far away)? This can be verified by uncommenting this line (around line 774) in DatabasePager.cpp. //osg::notify(osg::NOTICE)<<"_activePagedLODList.size()="<<_activePagedLODList.size()<<"\t_inactivePagedLODList.size()="<<_inactivePagedLODList.size()<<std::endl; If this can be confirmed then there is indeed a bug in DatabasePager.cpp. If not, then the implementation is correct and I'll have to try to figure out why my _activePagedLODList and _inactivePagedLODList are backwards. - -- Philip Lowman Simulation Development Engineer, Modeling and Simulation Technology General Dynamics Land Systems http://www.gdls.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.3 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFFp8XVe0tOktX6RKkRAobTAJ9S7oCJN4vY5NGXzNE4HKE0YJlsLwCdFD5t +I+zRwbm74yqBHT7ceiKFoE= =pGL2 -----END PGP SIGNATURE----- _______________________________________________ osg-users mailing list osg-users@openscenegraph.net http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
