Hi,
have a look at the osgautocapture example. Set the main camera to render
offscreen, pbuffer.

Hi,
I have an application where I setup a "normal" osgViewer view with
setUpViewOnSingleScreen(). This works fine.
I also create an FBO camera to which I add my scene. When I want to take a screenshot of
the application I call osgviewer->setSceneData(myFBOCamera) and render via
osgviewer->eventTraversal() / updateTraversal() / renderingTraversals(). After I get
the screenshot I restore my normal scene with osgviewer->setSceneData(mySceneData).
This also works fine for taking screenshots.
What I want to do now is to turn off the "main" camera whilst I render the FBO (ie if I create a lot of screenshots for a movie I don't want to render to the screen). How can I turn off the main camera and render only to the FBO?
I've tried calling osgviewer->setCamera(NULL) without sucess. Indeed when I meddle with the main camera I dont get a valid image from my FBO. I think this makes sense as the FBO is under the main camera(?).
I also tried calling osgviewer->setCamera(myFBO) but no luck that way either. I
also can't restore the original camera to the osgviewer.
Perhaps I am solving the problem the wrong way - is there a better method? Perhaps having
two seperate osgViewer objects? But then I think I have only one conceptual
"View" (my FBO always shows the same view as the main camera, it's only a
question of if the main camera should render an image or not), so having one Viewer, one
View and two Cameras feels correct - it's just that it doesn't work :-)
Thank you!
Cheers,
jake
