Hi Lv,
To scale to 100 of thousands of text labels you'd need to come up with a
custom implementation. osgText was never written to scale to that level,
and to do so in a general purpose class is not viable. It's not in any way
possible to actually read that many text labels so one has to ask at what
point do you plan of simplifying it so the user can actually read what is
going on screen.
For you application I believe you should work out exactly what high level
behaviour you want for your text labels - how they are aligned, blended
with the terrain, how they interact with each other, now they get LOD'd out
and in, how you might page the data if required, how many labels you'd want
on screen at one time. Once you have all this behaviour set then you start
designing an approach that can meet all of these requirements.
