[osg-users] Recognizing currently seen polygons / vertices?

[Robert Osfield]

Hi Arisgore,

I'm not surprised that no ones has replied in eight days.  I'd guess
most wouldn't know where to start.

First up I'd ask a big why do you want the vertex info?  What are you
trying to do with it.  This high level info is essentially in guiding
you in the right direction as your low level question may well be
heading in the wrong direction.

Robert.
