package DrawTrSurf
---Purpose: This package supports the display of parametric
-- curves and surfaces.
--
-- The Drawable deferred classes is inherited from
-- the Drawable3D class from the package Draw, it
-- adds methods to draw 3D Curves and Curves on 3D
-- Surfaces.
--
-- The classes Curve Curve2d and Surface are drawable
-- and can be used to draw a single curve from
-- packages Geom or Geom2d or a surface from Geom.
--
-- The Triangulation and Polygon from the package
-- Poly are also supported.

Set(Name : CString; G : Pnt from gp);
---Purpose: Sets <G> in the variable <Name>. Overwrite the
-- variable if already set.
Set(Name : CString; G : Pnt2d from gp);
---Purpose: Sets <G> in the variable <Name>. Overwrite the
-- variable if already set.
Set(Name : CString; G : Geometry from Geom);
---Purpose: Sets <G> in the variable <Name>. Overwrite the
-- variable if already set.
Set(Name : CString; C : Curve from Geom2d);
---Purpose: Sets <C> in the variable <Name>. Overwrite the
-- variable if already set.
Set(Name : CString; T : Triangulation from Poly);
---Purpose: Sets <T> in the variable <Name>. Overwrite the
-- variable if already set.
Set(Name : CString; P : Polygon3D from Poly);
---Purpose: Sets <P> in the variable <Name>. Overwrite the
-- variable if already set.
Set(Name : CString; P : Polygon2D from Poly);
---Purpose: Sets <P> in the variable <Name>. Overwrite the
-- variable if already set.
-- if the variable name is a void string a graphic selection is made.
Get(Name : in out CString) returns Geometry from Geom;
---Purpose: Get the variable <S>. Returns a null handle if
-- none, and print a warning message.
GetPoint(Name : in out CString; P : in out Pnt from gp)
returns Boolean;
---Purpose: Gets the variable. Returns False if none and print
-- a warning message.
GetPoint2d(Name : in out CString; P : in out Pnt2d from gp)
returns Boolean;
---Purpose: Gets the variable. Returns False if none and print
-- a warning message.
GetCurve(Name : in out CString) returns Curve from Geom;
---Purpose: Get the variable <S>. Returns a null handle if
-- none, and print a warning message.
GetBezierCurve(Name : in out CString) returns BezierCurve from Geom;
---Purpose: Get the variable <S>. Returns a null handle if
-- none, and print a warning message.
GetBSplineCurve(Name : in out CString) returns BSplineCurve from Geom;
---Purpose: Get the variable <S>. Returns a null handle if
-- none, and print a warning message.
GetCurve2d(Name : in out CString) returns Curve from Geom2d;
---Purpose: Get the variable <S>. Returns a null handle if
-- none, and print a warning message.
GetBezierCurve2d(Name : in out CString) returns BezierCurve from Geom2d;
---Purpose: Get the variable <S>. Returns a null handle if
-- none, and print a warning message.
GetBSplineCurve2d(Name : in out CString) returns BSplineCurve from Geom2d;
---Purpose: Get the variable <S>. Returns a null handle if
-- none, and print a warning message.
GetSurface(Name : in out CString) returns Surface from Geom;
---Purpose: Get the variable <S>. Returns a null handle if
-- none, and print a warning message.
GetBezierSurface(Name : in out CString) returns BezierSurface from Geom;
---Purpose: Get the variable <S>. Returns a null handle if
-- none, and print a warning message.
GetBSplineSurface(Name : in out CString) returns BSplineSurface from Geom;
---Purpose: Get the variable <S>. Returns a null handle if
-- none, and print a warning message.
GetTriangulation(Name : in out CString) returns Triangulation from Poly;
---Purpose: Get the variable <S>. Returns a null handle if
-- none, and print a warning message.
GetPolygon3D(Name : in out CString) returns Polygon3D from Poly;
---Purpose: Get the variable <S>. Returns a null handle if
-- none, and print a warning message.
GetPolygon2D(Name : in out CString) returns Polygon2D from Poly;
---Purpose: Get the variable <S>. Returns a null handle if
-- none, and print a warning message.
BasicCommands(I : in out Interpretor from Draw);
---Purpose: defines display commands.
