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

  Paraboloid Surface Parametric Equations

           x :=  u * cos(v);
           y :=  u * sin(v); 
           z :=  u * u ;
