deferred generic class ParTool from IntImpParGen
(ParCurve as any)
---Purpose: Template class for a tool on a parametrised curve.
uses Pnt2d from gp,
Vec2d from gp,
Lin2d from gp
is
Value (myclass; C: ParCurve; U: Real from Standard)
---Purpose: Returns the point at parameter U on the Curve C.
returns Pnt2d from gp;
D1 (myclass; C:ParCurve; U:Real from Standard ;
P: out Pnt2d; T: out Vec2d);
---Purpose: Computes the Point and the First derivative of
-- the parametric curve C at parameter U.
D2 (myclass; C:ParCurve; U:Real from Standard ;
P: out Pnt2d; T,N: out Vec2d);
---Purpose: Computes the Point, the First and the Second derivative of
-- the parametric curve C at parameter U.
EpsX (myclass; C: ParCurve)
---Purpose: Returns the valuec of the parametric tolerance
-- on the curve C.
returns Real from Standard;
NbSamples(myclass; C: ParCurve)
---Purpose: NbSamples is the number of sample point used to
-- polygonise the parametric curve on its domain.
returns Integer from Standard;
