void | Init (const Handle< Geom2d_TrimmedCurve > &bisector) |
Standard_Boolean | IsExtendAtStart () const |
Standard_Boolean | IsExtendAtEnd () const |
void | SetTrim (const Handle< Geom2d_Curve > &Cu) |
Trim <me> by a domain defined by the curve <Cu>. This domain is the set of the points which are nearest from <Cu> than the extremitis of <Cu>. | |
void | SetTrim (const Standard_Real uf, const Standard_Real ul) |
Trim <me> by a domain defined by uf and ul | |
void | Reverse () |
Changes the direction of parametrization of <me>. The "FirstParameter" and the "LastParameter" are not changed but the orientation of the curve is modified. If the curve is bounded the StartPoint of the initial curve becomes the EndPoint of the reversed curve and the EndPoint of the initial curve becomes the StartPoint of the reversed curve. | |
Standard_Real | ReversedParameter (const Standard_Real U) const |
Computes the parameter on the reversed curve for the point of parameter U on this curve. Note: The point of parameter U on this curve is identical to the point of parameter ReversedParameter(U) on the reversed curve. | |
Standard_Boolean | IsCN (const Standard_Integer N) const |
Returns the order of continuity of the curve. //! Raised if N < 0. | |
Handle_Geom2d_Geometry | Copy () const |
void | Transform (const gp_Trsf2d &T) |
Transformation of a geometric object. This tansformation can be a translation, a rotation, a symmetry, a scaling or a complex transformation obtained by combination of the previous elementaries transformations. (see class Transformation of the package Geom2d). //! The following transformations have the same properties as the previous ones but they don't modified the object itself. A copy of the object is returned. | |
Standard_Real | FirstParameter () const |
Returns the value of the first parameter. Warnings : It can be RealFirst or RealLast from package Standard if the curve is infinite | |
Standard_Real | LastParameter () const |
Value of the last parameter. Warnings : It can be RealFirst or RealLast from package Standard if the curve is infinite | |
Standard_Boolean | IsClosed () const |
Returns true if the curve is closed. Examples : Some curves such as circle are always closed, others such as line are never closed (by definition). Some Curves such as OffsetCurve can be closed or not. These curves are considered as closed if the distance between the first point and the last point of the curve is lower or equal to the Resolution from package gp wich is a fixed criterion independant of the application. | |
Standard_Boolean | IsPeriodic () const |
Returns true if the parameter of the curve is periodic. It is possible only if the curve is closed and if the following relation is satisfied : for each parametric value U the distance between the point P(u) and the point P (u + T) is lower or equal to Resolution from package gp, T is the period and must be a constant. There are three possibilities : . the curve is never periodic by definition (SegmentLine) . the curve is always periodic by definition (Circle) . the curve can be defined as periodic (BSpline). In this case a function SetPeriodic allows you to give the shape of the curve. The general rule for this case is : if a curve can be periodic or not the default periodicity set is non periodic and you have to turn (explicitly) the curve into a periodic curve if you want the curve to be periodic. | |
GeomAbs_Shape | Continuity () const |
It is the global continuity of the curve : C0 : only geometric continuity, C1 : continuity of the first derivative all along the Curve, C2 : continuity of the second derivative all along the Curve, C3 : continuity of the third derivative all along the Curve, G1 : tangency continuity all along the Curve, G2 : curvature continuity all along the Curve, CN : the order of continuity is infinite. | |
void | D0 (const Standard_Real U, gp_Pnt2d &P) const |
Returns in P the point of parameter U. If the curve is periodic then the returned point is P(U) with U = Ustart + (U - Uend) where Ustart and Uend are the parametric bounds of the curve. Raised only for the "OffsetCurve" if it is not possible to compute the current point. For example when the first derivative on the basis curve and the offset direction are parallel. | |
void | D1 (const Standard_Real U, gp_Pnt2d &P, gp_Vec2d &V1) const |
Returns the point P of parameter U and the first derivative V1. //! Raised if the continuity of the curve is not C1. | |
void | D2 (const Standard_Real U, gp_Pnt2d &P, gp_Vec2d &V1, gp_Vec2d &V2) const |
Returns the point P of parameter U, the first and second derivatives V1 and V2. //! Raised if the continuity of the curve is not C2. | |
void | D3 (const Standard_Real U, gp_Pnt2d &P, gp_Vec2d &V1, gp_Vec2d &V2, gp_Vec2d &V3) const |
Returns the point P of parameter U, the first, the second and the third derivative. //! Raised if the continuity of the curve is not C3. | |
gp_Vec2d | DN (const Standard_Real U, const Standard_Integer N) const |
For the point of parameter U of this curve, computes the vector corresponding to the Nth derivative. Exceptions StdFail_UndefinedDerivative if: | |

Standard_Real | Parameter (const gp_Pnt2d &P) const |
Standard_Real | ParameterOfStartPoint () const |
Standard_Real | ParameterOfEndPoint () const |
Standard_Integer | NbIntervals () const |
If necessary, breaks the curve in intervals of continuity <C1>. And returns the number of intervals. | |
Standard_Real | IntervalFirst (const Standard_Integer Index) const |
Returns the first parameter of the current interval. | |
Standard_Real | IntervalLast (const Standard_Integer Index) const |
Returns the last parameter of the current interval. | |
void | Dump (const Standard_Integer Deep=0, const Standard_Integer Offset=0) const |
