Hi Terry,
Both VPB and osgEarth seem to default to building scenegraphs with PagedLOD nodes, which I don't think will work for me. One option I thought of is to use VPB to create a big database in a single file with traditional LOD nodes, then use a separate program to convert it all to individual .flt tiles and a Metaflight file or something similar. I'll have to do more thinking about this option. Anyone know of any alternatives to Metaflight that can describe tiled databases but still let you store and edit tiles individually? I just want to consider all the options.
What's the specific problem with PagedLOD? You could still find the tile you want to modify, convert it to .flt (using osgconv with the flt write support in recent OSG versions), edit it, reconvert it to .ive (with osgconv, keeping the name the same) and run it.
Is the problem that the multiple LODs for the same region are not in the same file? That's not just caused by using PagedLOD, but also the fact that VPB (and I assume osgEarth too) make quadtree-LOD structures. If you needed all LODs of a given region to be in a single file, then all the geometry would be in a single file because the lowest-res LOD contains the geometry for the whole terrain. Tiles become more numerous and smaller as you go to higher-res LODs.
If you want to make all tiles at all LODs the same size, then I guess that could be added as an option in VPB. But then what would you replace PagedLOD with? ProxyNode?
