Hi Robert, It would be interesting to implement an interactive and improved version of ROAM or SOAR or even CLIPMAP for OSG. In vtp you can find standalone working implementations. Both would require paged DB. The internal representation would use different data structures. The only two OSG

Hi Alekandro, ChunkLOD is not CLOD, it's a static paged database, which really is far less use than what the OSG provides natively with its DatabasePager with VirtualPlanetBuilder generating the databases. As for CLOD implementations, most don't scale well, don't handle geocentric databases, and
