Definition of an ellipsoid.
It is centered on the origin of its canonical frame with its dimensions aligned with the frame's axes. The standard equation for the ellipsoid is:
x²/a² + y²/b² + z²/c² = 1,
where a,b,c are the lengths of the principal semi-axes of the ellipsoid. The bounding box of the ellipsoid is [-a,a]x[-b,b]x[-c,c].
