Oh my that's close, good to hear you've found a work around.  From the
sound of it, it looks very much like a driver bug, turning on/off
VBO's should not have any baring on the effect of
glPolygonOffset/depth buffer.

Hi

found the issue, thanks to a comment in another thread: the base surface had 
VBO turned on, but the highlighted area didn't. If they are both on or both 
off, then things display as expected on 10.8.

Lucky find the day before we ship, one less item for the known issues ;-)

 Hi
 
 I'm having a weird display issue when displaying lines and edges over a 
 surface on a Retina Mac.
 
 We display surfaces and when draw the boundary line and a subset of faces 
 (which are selected by the user) is also overlaid using faces in line 
 mode. See attached image if it's clearer…
 
 I normally works fine but on a MacBook Pro with a 15" Retina display 
 nothing shows.
 
 I've attached an osgt file that illustrates the issue. If you open in 
 osgviewer, you can't see the lines…
 
 Any ideas what may be going on?
 
 
 Cheers!
 
 
 Mike

Hi

ok, thanks for that. I'm still getting issues on an old non-retina MBP and on a 
new shiny retina MBP.
I'm not sync'ed up to SVN though… maybe a couple of months behind..

Hi Mike,

your test-file works on 10.8.2 and even with a simulated retina-display 
w/o problems. I am using the latest osg from svn/trunk

Re: [osg-users] Display of lines and edges on Retina/10.8 Mac

2013-01-21 Thread Robert Osfield 
Hi Mike,

I've tried the model out on my Kubuntu 12.10 system and all the lines
and mesh appear just fine, I would suspect a driver a bug.

I also looked the file and it looks reasonable, I presume you are
using osg::PolygonOffset to push the mesh behind the lines?  One thing
you could try is to adjust the PolygonOffset values to see if it makes
a difference.

You could also try running the model in osgviewer and toggle the
wireframe mode using 'w' and they rotating the scene to see if the
lines are being rendered at all.

Robert.

Hi

an update: still haven't found the reason for this, but it turns out if happens 
on a machine with 10.8 installed, not necessarily a Retina display.

Could someone with a 10.8 machine try opening the file attached in the original
