Convert_SphereToBSplineSurface Class Reference

This algorithm converts a bounded Sphere into a rational
B-spline surface. The sphere is a Sphere from package gp.
The parametrization of the sphere is
P (U, V) = Loc + Radius * Sin(V) * Zdir +
Radius * Cos(V) * (Cos(U)*Xdir + Sin(U)*Ydir)
where Loc is the center of the sphere Xdir, Ydir and Zdir are the
normalized directions of the local cartesian coordinate system of
the sphere. The parametrization range is U [0, 2PI] and
V [-PI/2, PI/2].
KeyWords :
Convert, Sphere, BSplineSurface.

DEFINE_STANDARD_ALLOC Convert_SphereToBSplineSurface (const gp_Sphere &Sph, const Standard_Real U1, const Standard_Real U2, const Standard_Real V1, const Standard_Real V2)
 The equivalent B-spline surface as the same orientation as the
sphere in the U and V parametric directions.
Raised if U1 = U2 or U1 = U2 + 2.0 * Pi
Raised if V1 = V2.

 Convert_SphereToBSplineSurface (const gp_Sphere &Sph, const Standard_Real Param1, const Standard_Real Param2, const Standard_Boolean UTrim=Standard_True)
 The equivalent B-spline surface as the same orientation
as the sphere in the U and V parametric directions.
Raised if UTrim = True and Param1 = Param2 or
Param1 = Param2 + 2.0 * Pi
Raised if UTrim = False and Param1 = Param2

 Convert_SphereToBSplineSurface (const gp_Sphere &Sph)
 The equivalent B-spline surface as the same orientation
as the sphere in the U and V parametric directions.
