Detailed Description

This class represents spheres.

Remarks: A sphere is defined by its radius center northAxis refAxis

northAxis defines the direction from the center to the north pole.

refAxis, a vector orthogonal to northAxis, the prime meridian.

Latitude is defined by the U parameter, which defaults to [-OdaPI/2, OdaPI/2] for closed spheres. The lower bound maps to the south pole, zero maps to the equator, and the upper bound maps to the north pole.

Longitude is defined by the V parameter, which defaults to [-OdaPI, OdaPI) for closed spheres. Zero corresponds to the meridian defined by the refAxis of this sphere.

The sphere is periodic in V with a period of Oda2PI.

[umin, umax] by [vmin, vmax] defines a spherical patch with 4 sides bounded by 2 longitudinal arcs and 2 latitudinal arcs.

The following constraints apply when defining a patch.

umin < umax and |umin - umax| <= Oda2PI. vmin < vmax and |vmin - vmax| <= OdaPI.

Corresponding C++ library: TD_Ge
