Question:
I would like to tack a question onto the "circle to ellipse" answer. The original question concerned determining your viewing angle based on the ellipse created by viewing a circle from an angle. If the object you are viewing from an angle is actually an ellipse with some known dimensions, let us say 10% longer in either the major or minor axis. Can the viewing angle still be determined?
Replies:
Without conducting a quantitative analysis by approaching this
qualitatively, it would seem that determining the angle of view
from a circle to an ellipse is the same absolute value of the angle
of view from an ellipse to a circle.
So determine what that 10% delta is, by working backwards to the
dimensions of the circle, and you should have the terms to determine
the angle of view.
