Hi Harash, I'm afraid I can't walk you through this, I have time to point you in the direction but no more than this.

Hi Mr. Robert. Thanks for the guidance on this issue. I have gone through the osgDistortion example and was able to render the monochrome image. But my requirement to process the captured image remained as it is. What I tried was: 1. Two Cameras were created -- one that renders the scene to a texture, and a second one that renders the texture on to the screen. But in this case, the accessibility to the image was not available. Next I attached an image object to the rendering camera. This image was set as the texture image and used by the second camera to render the processed image on to the screen. Camera->setPostDrawCallback was used to grab the image at every frame. When I did this, to my amazement, the framerate dropped from around 70 fps to 1 fps. I don't know if what I am doing is proper. If so, then is this drop in framerate expected. I am using 1024x1024 image size and to test I have applied no processing at all. Further, I am using a osgViewer::CompositeViewer. In this I want to have 2 views -- one that renders the usual colored scene while the other one that displays the processed monochrome scene. I am able to create the two views, but would like to take your guidance as to how to dynamically make one of them active while disabling the other one. Thanks in advance.
