Thank you all for your replies, links and info.

  I would manage something like millions of points, visualized as dots. 
Positions will be in a 3D coordinate cube, because usually they will 
represent particles in 3D space.

I'll take a deeper look at it, at first sight wasn't so clear to me.

That seems a good idea, and also your "benchmark"(17M points) looks 
promising. I've read that BGE support BGL v4, is it true?

Best,
Roberto
