class SphereToBSplineSurface from Convert
|
|
|
|
--- Purpose :
|
|
-- 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.
