Hi Rabbi,
As Jason points out if your are doing the write image from the main
loop and the view is multi-threaded then the main loop will be running
in a parallel with the rendering.
The way to do it properly is to use a final draw callback to capture
the image and then write it to the disk, or i

Hi Rabbi,
I'm afraid this still isn't enough information. Exactly how are you
doing the copy? Attaching an osg::Image to the osg::Camera? Using a
camera post draw callback? Doing your own gl code to do the copy in
some place in your application

Hi,
I add a camera to the scene that renders the texture I want and set the camera
to use pixel buffer. I am trying to do some preprocessing for the texture map
beforehand. The viewer is used only to render one frame or two before it
deconstructs.
The result is random, sometimes the rendered
Hi Rabbi,
You don't say how you are trying to copy the image, so there is really
very little one can add, you need to explain far more about your
viewer setup and how you are going about your copy image.

Hi,
I save it in a file. The problem is with frame(). If I call viewer.run() and
hit Esc to quit the viewer the image is complete.
Thank you!
Cheers,

Hi,
I have a code that creates a temporary viewer and uses it to render one frame
and copy from the color buffer to an image. When I call viewer.frame() the
rendered image is only half done. Is there anyone to tell the viewer to
complete a frame, save it and close itself?
Thank you!
Cheers,
