is
|
|
|
|
Value(myclass; C : Curve from Geom; U : Real; P : out Pnt);
|
|
---Purpose: Computes the point <P> of parameter <U> on the curve <C>.
|
|
|
|
D1 (myclass; C : Curve from Geom; U : Real; P : out Pnt; V1 : out Vec);
|
|
---Purpose: Computes the point <P> and first derivative <V1> of
|
|
-- parameter <U> on the curve <C>.
|
|
|
|
D2 (myclass; C : Curve from Geom; U : Real; P : out Pnt; V1, V2 : out Vec);
|
|
---Purpose: Computes the point <P>, the first derivative <V1> and second
|
|
-- derivative <V2> of parameter <U> on the curve <C>.
|
|
|
|
D3 (myclass; C : Curve from Geom; U : Real;
|
|
P : out Pnt; V1, V2, V3 : out Vec);
|
|
---Purpose: Computes the point <P>, the first derivative <V1>, the
|
|
-- second derivative <V2> and third derivative <V3> of
|
|
-- parameter <U> on the curve <C>.
|
|
|
|
Continuity(myclass; C : Curve from Geom) returns Integer;
|
|
---Purpose: returns the order of continuity of the curve <C>.
|
|
-- returns 1 : first derivative only is computable
|
|
-- returns 2 : first and second derivative only are computable.
|
|
-- returns 3 : first, second and third are computable.
|
|
|
|
FirstParameter(myclass; C : Curve from Geom) returns Real;
|
|
---Purpose: returns the first parameter bound of the curve.
|
|
--
|
|
|
|
LastParameter(myclass; C : Curve from Geom) returns Real;
|
|
---Purpose: returns the last parameter bound of the curve.
|
|
-- FirstParameter must be less than LastParamenter.
