I would like to implement a LOD mechanism to display vector POIs.
The density of POIs should be high near the camera and decreasing with
the distance: far POIs should be aggregated.
Would using a QuadtreePrimitive to create Billboards /
BillboardCollections on the fly makes sense?
Have someone tried this strategy / have some performance numbers?
The QuadtreePrimitive is currently private, will it change in the future?
