Spheroid – Wikipedia
A spheroid, also known as an ellipsoid of revolution or rotational ellipsoid, is a quadric surface obtained by rotating an ellipse about one of its principal axes; in other words, an ellipsoid with two equal semi-diameters.A spheroid has circular symmetry.. If the ellipse is rotated about its major axis, the result is a prolate spheroid, elongated like a rugby ball.

A spheroid is an ellipsoid having two axes of equal length, making it a surface of revolution. By convention, the two distinct axis lengths are denoted a and c, and the spheroid is oriented so that its axis of rotational symmetric is along the z-axis, giving it the parametric representation x = asinvcosu (1) y = asinvsinu (2) z = ccosv, (3) with u in [0,2pi), and v in [0,pi].
