Thanks for the link. Performance with point clouds is principally and memory management, either getting all the data local to the GPU if possible, if not chunking the data into appropriate sizes for streaming the GPU. 5GB would be a good stress test for managing data on the GPU. Point cloud rendering is a special case of rendering so won't challenge most of design and implementation of a scene graph so I'm keen to find more conventional vis-sim, game and modelling/CAD datasets as well.
