Unfortunately, that's just a limitation of the visitor pattern and double dispatch in general. In order to accomplish what you want, you'd have to overload apply(osg::Group) forward the call explicitly. Something like: MyVisitor::apply(osg::Group grp) { if( dynamic_castosg::MyGroup*(grp) )

The process I use: - copy master.flt to another directory (hopefully the file references aren't absolute paths) - use osgDB:readNodeFile to read the copied master.flt. This places osg::ProxyNodes in place of the actual .flt reference files (because it can't find the referenced files) - write a

Generally, the master.flt does not have any knowledge about the location and extents of the external files that it calls. This is the information that the pager would require. What we do is to run a separate app that runs through all of the db tiles one time, and creates a text file of the
