Re: [osg-users] Callback when loading nodes in the database pager
Hi Ralf, Christophe We use ReadFileCallback to modify requested nodes from database pager. It works fine, but make sure Your code is thread safe. Regards, Maciej 2008/12/18 christophe loustaunau christophe.loustau...@gmail.com Hi Ralf, look at ReadFileCallback in the example osgCallBack, it may be what you wan't. Regards.

Re: [osg-users] Callback when loading nodes in the database pager
Hi Both Thanks for the hints, ReadFileCallback defenatly seams like it would solve most of my problem. How do I determine if the file loaded was part of my terrain or another specifik pagedLod dataset, and as such should be handled in the filecallback? Brgs.
