Working on creating a universe like model, where there could be millions of data points.  I currently place all my vectors, colors, etc into a VBO.  But how large can this scale... I expect that you really don't want to draw more than a 100,000 objects in your scene and fade/clip out the rest.  But at some point, you have to be able to move through that universe and access the other million data points. You may need to search those data points, and fly to them.  Has anyone had any experinece with how you would go about refreshing the VBO as you move through space like that.  Perhaps using a Graph database like Neo4j or OrientDB?  I'm not sure that would contain the vectors.. how would you know which data points to load/draw?  Would you pull the entire data set into memory?  Thanks for any direction you can provide.
