I figured it would be like looking through a window - it doesn't matter what shape the frame is, what you see on the other side has the same proportions. I guess to me at least (relatively inexperienced with POV - all I do is modify camera positions and the background color), it doesn't make much sense. -Tim

(...) No, POV-Ray's rendering engine doesn't really care what the dimensions of your image are. It only cares about what you tell it the aspect ratio is. If you render with a default camera (4/3 ratio) to a square output image, you'll get an image (...) (23 years ago, 20-Dec-01, to lugnet.publish, lugnet.general, lugnet.cad.ray)
