Rendering very large point data clouds is specialist problem with very specific needs compared to rendering traditional polygonal scenes. To get the best results for your particular problem then coming up with custom approaches may well be best. One trick I've used in the past with point clouds is to trade point size for point density - this works well when the point clouds represent surface data such as collected by radar or laser scanning of 3D objects or environments. If you have normal and colour data using point sprites can work really well at filling in the gaps between points, which in turn means you can get away with lower point density and still have a compelling visual.
