Hi Stephan,
thank you for your reply.
After I compared my project with the iPhone-Example on github, I found out that
the file PerlinNoise.cpp is missed in OpenSceneGraph-3.0.1-zip (which I
downloaded from OSG-Website). This was the reason for the osgUtil-error
mentioned above.

The following seems to work :

Could you explain me the difference between these 3 parameters ?

I try the RTT master camera and for one view it works fine, but when I want to

Only the first view get a new viewmatrix.
There are any experiance about rtt cameras and camera manipulators?
Thank you!

Have you seen the qml ogre demo? I assume you could do the same thing for osg.

Hi, all,
I'm interested in determining how many OpenGL draw calls are made during
the rendering of a frame (counting and storing them as a Stats
variable). I'm sure this is possible, but I wonder if it would be
feasible to do without significantly affecting performance.
Anyone have any
gDEBugger has the ability to view OpenGL Call history.
Can't speak on the performance hit.
But, sounds like you need it in the app itself.
I don't know of an internal mechanism.
However, should be able to easily CASE a thin inlined OpenGL layer with metrics
embedded.

Thanks, Bob.
I've used gDEBugger for this before, but for this case, I need to get it
into the OSG Stats proper. The capability isn't there yet, so I'm
looking into adding it. I'm trying to gauge how feasible it would be to
add this feature without adversely affecting performance.
The
OpenGL video driver comes to mind.
Anything in the spec that facilitates this across platforms?

Hi Chris,
Can you give a bit more info about what you've tried and why it isn't working?
I haven't worked with osgViewerQt before, but it looks like it inherits from
osgViewer::Viewer, runs in single threaded mode, and frame() is called by the
paintGL method, which is presumably triggered by
