Provides methods to intersect two conics. The exception ConstructionError is raised in constructors or in Perform methods when a domain (Domain from IntRes2d) is not correct, i-e when a Circle (Circ2d from gp) or an Ellipse (i-e Elips2d from gp) do not have a closed domain (use the SetEquivalentParameters method for a domain on a circle or an ellipse).

Constructors(1)

constructor(): IntCurve_ProjectOnPConicTool

Static methods(2)

FindParameter(C: IntCurve_PConic, Pnt: gp_Pnt2d, Tol: number): number
Returns the parameter V of the point on the parametric curve corresponding to the Point Pnt. The Correspondence between Pnt and the point P(V) on the parametric curve must be coherent with the way of determination of the signed distance between a point and the implicit curve. Tol is the tolerance on the distance between a point and the parametrised curve. In that case, no bounds are given. The research of the right parameter has to be made on the natural parametric domain of the curve.
Parameters (3)
- C
- Pnt
- Tol
FindParameter(C: IntCurve_PConic, Pnt: gp_Pnt2d, LowParameter: number, HighParameter: number, Tol: number): number
Returns the parameter V of the point on the parametric curve corresponding to the Point Pnt.
The Correspondence between Pnt and the point P(V) on the parametric curve must be coherent with the way of determination of the signed distance between a point and the implicit curve. Tol is the tolerance on the distance between a point and the parametrised curve. LowParameter and HighParameter give the boundaries of the interval in which the parameter certainly lies. These parameters are given to implement a more efficient algorithm. So, it is not necessary to check that the returned value verifies LowParameter <= Value <= HighParameter.

- Pnt
