---Purpose: Set parametric information
|
|
-- [<First>, <Last>] Sets the parametric bound of the
|
|
-- sweeping surface to build.
|
|
-- <SectionFirst>, <SectionLast> gives coresponding
|
|
-- bounds parameter on the section law of <First> and <Last>
|
|
--
|
|
-- V-Iso on Sweeping Surface S(u,v) is defined by
|
|
-- Location(v) and Section(w) where
|
|
-- w = SectionFirst + (v - First) / (Last-First)
|
|
-- * (SectionLast - SectionFirst)
|
|
--
|
|
-- By default w = v, and First and Last are given by

|
|
---Purpose: Set Approximation Tolerance
|
|
-- Tol3d : Tolerance to surface approximation
|
|
-- Tol2d : Tolerance used to perform curve approximation
|
|
-- Normaly the 2d curve are approximated with a
|
|
-- tolerance given by the resolution method define in
|
|
-- <LocationLaw> but if this tolerance is too large Tol2d
|
|
-- is used.
|
|
-- TolAngular : Tolerance (in radian) to control the angle
|
|
-- beetween tangents on the section law and
|
|
-- tangent of iso-v on approximed surface

---Purpose: Build the Sweeep Surface
|
|
-- ApproxStyle defines Approximation Strategy
|
|
-- - GeomFill_Section : The composed Function : Location X Section
|
|
-- is directly approximed.
|
|
-- - GeomFill_Location : The location law is approximed, and the
|
|
-- SweepSurface is build algebric composition
|
|
-- of approximed location law and section law
|
|
-- This option is Ok, if Section.Surface() methode
|
|
-- is effective.
|
|
-- Continuity : The continuity in v waiting on the surface
|
|
-- Degmax : The maximum degree in v requiered on the surface
|
|
-- Segmax : The maximum number of span in v requiered on
|
|
-- the surface
