ELLIPSE crosswise.semiaxis inline.semiaxis

Draws an ellipse based on the turtle heading, turtle position, and given inputs. The center-point of the ellipse is the turtle's current position. ELLIPSE does not move the turtle. The size and shape of the ellipse is based on the crosswise.semiaxis and inline.semiaxis inputs. The crosswise.semiaxis input is the distance from the turtle to the ellipse in the direction perpendicular turtle's current heading. The inline.semiaxis input is the distance from the turtle to the ellipse in the direction which the turtle is currently heading.
