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.
