This algorithm converts a bounded cylinder into a rational
B-spline surface. The cylinder is a Cylinder from package gp.
The parametrization of the cylinder is :
P (U, V) = Loc + V * Zdir + Radius * (Xdir*Cos(U) + Ydir*Sin(U))
where Loc is the location point of the cylinder, Xdir, Ydir and
Zdir are the normalized directions of the local cartesian
coordinate system of the cylinder (Zdir is the direction of the
cylinder's axis). The U parametrization range is U [0, 2PI].

Convert, Cylinder, BSplineSurface.
