Hi Hannes,
The OSG has native database paging rather nullifies the need for a
ChunkLOD implementation.
Vladimir's previous work on ChunkLOD/OSG implementation was done
before VirtualPlanetBuilder/osgTerrain/osgDB::DatabasePager really
got off the ground.
hi robert,
someone from the project came up with this question:
I think this demo never became part of OSG, which is also what Robert
states in his response to your question. Anyway, I don't get what
exactly he's talking about in terms of the relationship between
ChunkedLOD and osgDB::DatabasePager. The chunking aspect in
ChunkedLOD refers to the fact the rendering algorithm divides the
terrain mesh into individual chunks that can be sent to the gfx
adapter separately, eliminating the need to re-build the whole mesh
every time the camera perspective changes. In my understanding,
osgDB::DatabasePager is used to load terrain tiles in a background
thread, but is not directly to the actual rendering operations.
kind regards
