The ellipsoids are a 3 parameter family of quadratic algebraic surfaces
that (up to a rigid motion) can be put into the form:
(x/a)^2 + (y/b)^2 + (z/c)^2 = 1.
The three parameters a,b,c are called the semi-axes of the ellipsoid.
When two of them are, the ellipsoid is called a spheroid and in
this case the ellipsoid is a surface of revolution. Of course, when
all three are equal, the ellipsoid is a sphere.

See QuadraticSurfaces.pdf.
Other algebaric surfaces that has cross-sections of conic sections are:
ellipsoid,
paraboloid,
hyperbolic paraboloid,
hyperboloid of one sheet,
hyperboloid of two sheets

Ellipsoid Surface Parametric Equations
x = aa * (cos(u) * sin(v))
y = bb * (sin(u) * sin(v))
z = cc * (cos(v))
