Hi,
I have somewhat similar questions to recent FBO question,
but not quite, so I would ask in a new thread.
I try to extend Blender with osg rendering ( just because osg does many
things better than Blender namely I use osgPango to render dynamically
text).
First - it is fairly easy to create
So, along the same lines...
One of these views contains a windowmanager that controls my 2D GUI that I want

In this function you will see how a cameras BufferAttachment list is used to

The issue was that I had the box's GL_DEPTH_TEST set to off.

Boeing's multipurpose viewer (MPV) was designed to simply be a test harness
for the CIGI protocol. It's a far cry from it being used as a general
purpose IG.

CIGI uses UDP so updating osgVisual to use CIGI shouldn't be an issue in

CIGI is an industry standard for controlling most aspects of an Image
Generator. This includes ownship and entity behaviors along with a lot of
other stuff. Most commercial IG vendors support CIGI.

Thanks for your reply. Yes, odd things are certainly happening. From what I am
observing it would be more sensible to create the camera at start time.

Yes you can use a framebufferobject as a render to texture target, checkout
the osgprerender example. If you want to use the result of your render in

Hi Robert,
(I have modified my graph in my last post because it was not clearly displayed.)
So, I understand what you mean. I have made such graph because geode 2 follow

I will try the solution to make geode1 and geode2 independents.
Thank you.

You can simply assign the float array to an osg::Image and then attach

Hi Martin,
The rendering backend is identical between Viewer and CompositeViewer
so both are fully capable of doing stereo. I presume the issue comes
from the DisplaySettings hints used to pass in the stereo settings.
With CompositeViewer each View can have it's own DisplaySettings

Do you mean multiple View's withing a CompositeViewer? While it's

In terms of closing a View, does this View have it's o
