Hi Ferdi, The VirtualTerrainProject adds a number of continuously level of detail implementations on top of the OSG so you could look at this for inspiration.
Personally I feel that doing meshing per frame on the CPU is had it's day, and graphics hardware is better driven using data that is download as static blocks to the GPU, and then rendered locally. You can render scenes with a million vertices on screen at one time quite comfortable at 60Hz on modern hardware so you aren't fighting with GPU capabilities these days, bandwidth and memory management and CPU loads are far more critical good performance - something that CPU based meshing is very poor at. You can of course mesh on the GPU these days too :-) Robert.
