Hi Shayne,
I vaguely VPB having inbuilt support for keeping a lid on the number
of open file handles. I don't recall the specifics though, it's a
couple of years since I wrote this part of VPB, perhaps we need to
update the mechanism to query how many open files are supported and
adjust it so

Is it possible to do something between two render passes? I render an image

render the final image on the screen.
I use the osg::Camera with PRE_RENDER and the FRAME_BUFFER_OBJECT. And this

Hi,
here's a very special case of Qt integration for OpenSceneGraph for
which I am searching for a solution: We're using Qt to draw into a
QPixmap (updating a map of measured radio conditions during a
simulation in realtime). We optionally support a 3D display, which is
typically a line by line
Hi Martin,
All you need to do is attach a post draw callback to the pre rendering camera.

Yes, I made a quick try with it, but the project that has been generated

I tried again with the latest OSG source from svn but I still have problems.

Most peculiar artifact. What happens when you run the osgtext and

Hi Serge,
Good to hear that obtaining the fonts has fixed things. In theory you
should have been able to fix up the fonts from OpenSceneGraph-Data,
and since you had cow.osg I assumed that you had everything you
needed.
Not having fonts available should make osgText fallback to the inbuilt
Hi,
To clarify my last message, my point is that you get correct frame with
interpolation, but by the time frame rendered your simulation results outdated.
Follow this basic example:

Hi,
First, make sure that your popup windows have the mainwindow as their parent.
Second, this happens a lot when you do full screen applications. One thing you
may try is calling QWidget::raise() on your dialogs. The raise slot brings the
widget to the top and will visually be in front of

This is an example of how i convert QImage to osg::texture:

Hi Christian,
In svn/trunk version of the OSG (and 2.9.10) there is the osgQt

ability to take the contents of Qt widgets and render them in 3D
objects as textures.
There is also a mechanism for passing OSG events back to Qt so

That did the trick. Luckily the code to apply an ARB shader is consolidated to

Well, I've been able to change the 48 small triangle strips per geometry

The result is a small but noticeable decrease in draw time. It's smaller

If I understand correctly how the sky dome mesh is constructed, there was a
lot of duplication of vertices in the triangle strip arrays, and this has
been carried forward into your indexed mesh approach. The INDEX_MESH

Unless you're debugging into OSG code, I would not use the debug libraries.
Things will run SLOOOW.
