Hi,
Thank you for your suggestions! I think the scribe effect is probably
what I want for selection.
You mentioned something about unreferencing data on the CPU side once
it is uploaded. I am quite interested in this. Could you please give
me more details?
A search for "UnRef" in the OSG includes will give you some details.
I've only used this with textures though, so to be honest I don't know
if similar techniques can be used for other data.
Honestly speaking, the 2 million points and lines are probably not
the largest dataset I will encounter. During the last few days, I
discovered that my viewer probably has an acceptable performance, but
the large amount of memory that it uses is probably the main issue I
need to deal with. If there are some ways that can reduce the size of
the scene graph or cache inactive part of the scene graph on disk, I
would like to give them a try.
When you say memory do you mean CPU/GPU? PagedLOD can maybe help with this.

Thank you!
Cheers, Angus
