A paraboloid is defined by the revolution surface generated by a parabola and is bounded by two planes perpendicular to Z axis.

The parabola equation is taken in the form: z = a·r2 + b, where: r2 = x2 + y2. Note the missing linear term (parabola symmetric with respect to Z axis).

The coefficients a and b are computed from the input values which are the radii of the circular sections cut by the planes at +/-dz:

-dz = a*r2low + b
dz = a*r2high + b

TGeoParaboloid(Double_t rlo,Double_t rhi,Double_t dz);
