Hi,
Small update on this: I tried gDEBugger (found via cnet.com) but it
won't run on current OSX anymore. So no luck there.
I will look into apitrace when there is time... Keep you posted.
Cheers
Raymond

Raymond, try gDebugger (there is release for Mac OS too) or this
apitrace. You can easely catch the OpenGL: error - with gDebugger it
can show you the source code line producing the error

Hi Robert,
Ouch, typo, I meant to set the OSG_GL_ERROR_CHECKING properly...
I am afraid this won't provide more info neither:

OSG_GL_ERROR_CHECKING=ONCE_PER_ATTRIBUTE
MB:~ ray$ env | grep NOTIFY

When I have more time, I will dig into it more. Do you have other
suggestions in the mean time?

Hi Raymond,
Unfortunately the output doesn't yet provide anything clearer
to what
might be amiss.
Could you try the test with the env OSG_GL_ERROR_CHECKING set to
ONCE_PER_ATTRIBUTE, setting the env var to OSG_GL_ERROR_CHECKINGas
your specified will not change the setting, so will default to
ONCE_PER_FRAME.

Hi,
I did another test and the output with default settings is
(NOTICE):

Setting OSG_GL_ERROR_CHECKING=OSG_GL_ERROR_CHECKING does
not make a
difference in output.
Setting OSG_NOTIFY_LEVEL to INFO reveals this part that
might be
interesting:

Hi Robert,
Yes, indeed, that's the OpenGL error. I have build the
same version on
Windows (nvidia card) and no such error so I am not
sure of course if it has
to do with OSX or not.
The last version that I checked was 3.5.4 and that one
doesn't produce the
errors. Indeed, I tested it explicitly because of the
VAO changes.
Later, I will produce more results and post them.
Regards,
Raymond

Hi Raymond,
Thanks for the logs, unfortunately the debug logs
actually make it
more difficult to spot the actual errors. The
only error I spotted
was:
Warning: detected OpenGL error 'invalid operation'
at after
RenderBin::draw(..)
Is this the error you are thinking of?
Could you set the OSG_NOTIFY_LEVEL back to NOTICE
and the env
OSG_GL_ERROR_CHECKING env var to ONCE_PER_ATTRIBUTE
This hopefully will enable us to home in a bit
more closely to what
might be causing the GL error.
Another useful bit of information is the last OSG
version that doesn't
report the above error on our system. It could be
that the cause of
the GL error precedes the VAO work.
Cheers,
Robert.

Hi Robert,
I just tried a build from this mornings git
master on my Mac book (up to
date OSX and dependencies) and both the
default and VAO paths result in
OpenGL errors. I have attached 2 (stripped)
logs which I created after I
increased the notify level. Rendering results
of cow, cessna and some
other
models look ok.
I was going to try gdebugger but that one is
not available anymore?! If
you
have some hints to produce more info I am
happy to test some more.
Cheers
Raymond
