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 custom NodeVisitor to convert the osg::ProxyNodes to osg::PagedLODs - at the same time I convert the referenced .flts to .ives and use their bounds to set the osg::PagedLODs center and radius. - save the master.flt as master.ive (or master.osg)

I'm not sure if osgviewer is doing this already? or wether I should use osgpagedLOD example to load in my database - if so how? Also down the track I would like to know which tiles are being loaded in and which tiles are being loaded out. Where would I be able to find the relevant point in the source code? Thank you and Merry Xmas _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- This is a PRIVATE message.
