--- Purpose : Provides the required methods to instantiate
|
|
-- CGProps from GProp with a Curve from BRepAdaptor.

|
|
|
FirstParameter (myclass; C : Curve from BRepAdaptor) returns Real;
|
|
--- Purpose :
|
|
-- Returns the parametric value of the start point of
|
|
-- the curve. The curve is oriented from the start point
|
|
-- to the end point.
|
|
|
|
|
|
LastParameter (myclass; C : Curve from BRepAdaptor) returns Real;
|
|
--- Purpose :
|
|
-- Returns the parametric value of the end point of
|
|
-- the curve. The curve is oriented from the start point
|
|
-- to the end point.
|
|
|
|
|
|
IntegrationOrder (myclass; C : Curve from BRepAdaptor) returns Integer;
|
|
--- Purpose :
|
|
-- Returns the number of Gauss points required to do
|
|
-- the integration with a good accuracy using the
|
|
-- Gauss method. For a polynomial curve of degree n
|
|
-- the maxima of accuracy is obtained with an order
|
|
-- of integration equal to 2*n-1.
|
|
|
|
|
|
Value (myclass; C : Curve from BRepAdaptor; U : Real) returns Pnt;
|
|
--- Purpose : Returns the point of parameter U on the loaded curve.

|
|
|
|
D1 (myclass; C : Curve from BRepAdaptor; U: Real; P: out Pnt; V1: out Vec);
|
|
--- Purpose :
|
|
-- Returns the point of parameter U and the first derivative
|
|
-- at this point.
|
|
|
|
NbIntervals(myclass; C : Curve from BRepAdaptor; S : Shape from GeomAbs)
|
|
---Purpose: Returns the number of intervals for continuity
|
|
-- <S>. May be one if Continuity(me) >= <S>
|
|
returns Integer;
|
|
|
|
Intervals(myclass; C : Curve from BRepAdaptor;
|
|
T : in out Array1OfReal from TColStd;
|
|
S : Shape from GeomAbs)
|
|
---Purpose: Stores in <T> the parameters bounding the intervals
|
|
-- of continuity <S>.
|
|
--
|
|
-- The array must provide enough room to accomodate
|
|
-- for the parameters. i.e. T.Length() > NbIntervals()
