An ellipse is nothing more than a circle projected in 3d? ;^) An ellipse, take a parametric circle and use different x and y radii. However, Think of rotating a circle in a 3d projection. It visually looks like an ellipse. So, I always found that interesting. If I take an ellipse in 2d, it has a rotated circle "counterpart" in 3d? Fair enough, kind of? ;^) So, take an ellipse as a parametric circle with different x and y radii. Well, it has a counterpart circle that is rotated in 3d. Fair enough?
