[osg-users] Get all vertices of an OSG Group

[Sebastian Messerschmidt]

Hi Clement,

Can you give us an example file? Somehow the last sentence doesn't make 
much sense.

If your geometry is textured, it might not have any material or vertex 
colors assigned. In this case it is not simple to "get the colors", 
because you will effectively end up duplicating the state structure and 
data.
What exactly are you trying to achieve?
