class Sweep from GeomFill
---Purpose: Geometrical Sweep Algorithm
---Level: Advanced
uses
SectionLaw from GeomFill,
LocationLaw from GeomFill,
ApproxStyle from GeomFill,

Surface from Geom,
Curve from Geom2d,

is
Create(Location : LocationLaw from GeomFill;
WithKpart : Boolean = Standard_True)
returns Sweep from GeomFill;
SetDomain(me : in out; First, Last : Real;
SectionFirst, SectionLast : Real);
---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
-- First and Last parameter stored in LocationLaw.
SetTolerance(me : in out;
Tol3d : Real;
BoundTol : Real = 1.0;
Tol2d : Real = 1.0e-5;
TolAngular : Real = 1.0);
---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
ExchangeUV(me)
---Purpose: returns true if sections are U-Iso
-- This can be produce in some cases when <WithKpart> is True.
returns Boolean from Standard
is static;
UReversed(me)
---Purpose: returns true if Parametrisation sens in U is inverse of
-- parametrisation sens of section (or of path if ExchangeUV)
returns Boolean from Standard
is static;
VReversed(me)
---Purpose: returns true if Parametrisation sens in V is inverse of
-- parametrisation sens of path (or of section if ExchangeUV)
returns Boolean from Standard
is static;
Build(me : in out;
Section : SectionLaw from GeomFill;
Methode : ApproxStyle = GeomFill_Location;
Continuity : Shape = GeomAbs_C2;
Degmax : Integer = 10;
Segmax : Integer = 30)
---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
--
-- raise If Domain are infinite or Profile not Setted.
