I was wondering, if I have an OPENGL sketch with 3D, would it be possible to have multiple camera positions in the same image? 

For example: I put a circle in the center and rotate a bit. Now, with the default camera settings you see the circle in perspective. If I would want the same circle with the same rotation and perspective translated to the right, next to the original one, would that be possible? 

I would assume that if this would be possible it would involve moving the camera and the frustum, but I'm not sure if this is possible... 

Any ideas?
