class CylinderToBSplineSurface from Convert
|
|
|
|
--- Purpose :
|
|
-- 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].
|
|
--- KeyWords :
|
|
-- Convert, Cylinder, BSplineSurface.
