A quick comment first, it has been a couple of years since I have used

Hi All,
I need to implement a dynamic 'drawing' overlay that is rendered onto a
model created using vpb. Has anyone tackled this so far?
My first thought is to use the osgSim Overlay as I have used this to do
the same thing on a flat world. Should this work for a geocentric model?

Hi Teodor,
I'm not sure if this is a common problem, but in the company I work
for we have never been able to get quad buffered stereo to work in a

that it is a driver issue and reported it to nVidia, but thus far

More generally I'm not convinced that we need to deprecate the none
ref versions. I'd be inclined towards just documenting that
multi-threaded reads should use the Ref versions.
It might not be convincing to have to go back to the code base and remove these
unsafe sections of code, but
Hi J-S,
Viewer::updateTraversal() and CompositeViewer::updateTraversal() both
traverse the scene graph and explictly camera's update callbacks.
What these updateTraversal() methods do is switch of the traversal of
the camera's subgraph when the camera subgraphs are traversed, so the

That problem looks like a driver issue, indeed. However, I vaguely
recall that in Windows the stereo had to be enabled in two places -
first checkbox turned on the quad buffer support and the other stereo

I have followed all the instructions on NVIDIA page to enable the stereo, and

In examining the output from the compile, it appears that the header files get
moc'ed. Also I get a few moc-prefixed CPP files in my source dir from some of
the QOSGWidget headers.

Hi Colin,
I tried adding an update callback to the top level camera and that did
work. I checked the code and it does call accept:

_camera-accept(*_updateVisitor.get());
So it should work correctly (as of 2.8.2)
Sorry, I was mistaken in saying that the cameras did not get the update
Hi Robert,
What these updateTraversal() methods do is switch of the traversal of
the camera's subgraph when the camera subgraphs are traversed, so the
children won't be traversed. This is done so that the scene graphs
aren't traversed multiple times per frame, but... I believe in your
case
Thanks Alberto! This helped. More specifically, disabling this option helped to
allow osgUtil to build. (building osg 2.9.6)
