Standard_EXPORT | GCE2d_MakeParabola (const gp_Parab2d &Prb) |
Creates a parabola from a non persistent one. . | |
Standard_EXPORT | GCE2d_MakeParabola (const gp_Ax22d &Axis, const Standard_Real Focal) |
Creates a parabola with its local coordinate system and it's focal length "Focal". The "Location" point of "Axis" is the vertex of the parabola Status is "NegativeFocusLength" if Focal < 0.0 . | |
Standard_EXPORT | GCE2d_MakeParabola (const gp_Ax2d &MirrorAxis, const Standard_Real Focal, const Standard_Boolean Sense) |
Creates a parabola with its "MirrorAxis" and it's focal length "Focal". MirrorAxis is the axis of symmetry of the curve, it is the "XAxis". The "YAxis" is parallel to the directrix of the parabola. The "Location" point of "MirrorAxis" is the vertex of the parabola Status is "NegativeFocusLength" if Focal < 0.0 . | |
Standard_EXPORT | GCE2d_MakeParabola (const gp_Ax22d &D, const gp_Pnt2d &F) |
Creates a parabola with the local coordinate system and the focus point. The sense of parametrization is given by Sense. . | |
Standard_EXPORT | GCE2d_MakeParabola (const gp_Ax2d &D, const gp_Pnt2d &F, const Standard_Boolean Sense=Standard_True) |
D is the directrix of the parabola and F the focus point. The symmetry axis "XAxis" of the parabola is normal to the directrix and pass through the focus point F, but its "Location" point is the vertex of the parabola. The "YAxis" of the parabola is parallel to D and its "Location" point is the vertex of the parabola. . | |
Standard_EXPORT | GCE2d_MakeParabola (const gp_Pnt2d &S1, const gp_Pnt2d &O) |
Make a parabola with focal point S1 and center O The branch of the parabola returned will have <s1> as focal point The implicit orientation of the parabola is: - the same one as the parabola Prb, - the sense defined by the coordinate system Axis or the directrix D, - the trigonometric sense if Sense is not given or is true, or - the opposite sense if Sense is false. Warning The MakeParabola class does not prevent the construction of a parabola with a null focal distance. If an error occurs (that is, when IsDone returns false), the Status function returns: - gce_NullFocusLength if Focal is less than 0.0, or - gce_NullAxis if points S1 and O are coincident. . | |
Standard_EXPORT const Handle_Geom2d_Parabola & | Value () const |
Returns the constructed parabola. Exceptions StdFail_NotDone if no parabola is constructed. . | |
Standard_EXPORT const Handle_Geom2d_Parabola & | Operator () const |
