[osg-users] Cloning text

[Andreas Ekstrand]

Hi,

I'm using osgText to show vertex numbers. Often enough it's only 0,1,2 
for triangles but it can be several hundred thousands of them.

It's never been optimal, I know - and I guess this is the time to do 
something about it, I will look into an alternative way without osgText. 
Any suggestions are welcome!

Regards,
Andreas
