Ellipses also arise as images of a circle or a sphere under parallel projection, and some cases of perspective projection. An ellipse is also the closed and bounded case of an implicit curve of degree 2, and of a rational curve of degree 2. It is also the simplest Lissajous figure, formed when the horizontal and vertical motions are sinusoids with the same frequency.
