Standard_EXPORT | GccAna_Lin2d2Tan (const gp_Pnt2d &ThePoint1, const gp_Pnt2d &ThePoint2, const Standard_Real Tolerance) |
This methods implements the algorithms used to create 2d lines passing thrue 2 points. Tolerance is used because we can't create a line when the distance between the two points is too small. . | |
Standard_EXPORT | GccAna_Lin2d2Tan (const GccEnt_QualifiedCirc &Qualified1, const gp_Pnt2d &ThePoint, const Standard_Real Tolerance) |
This methods implements the algorithms used to create 2d lines tangent to one circle and passing thrue a point. Exception BadQualifier is raised in the case of EnclosedCirc Tolerance is used because there is no solution when the point is inside the solution according to the tolerance. . | |
Standard_EXPORT | GccAna_Lin2d2Tan (const GccEnt_QualifiedCirc &Qualified1, const GccEnt_QualifiedCirc &Qualified2, const Standard_Real Tolerance) |
This methods implements the algorithms used to create 2d lines tangent to 2 circles. Exception BadQualifier is raised in the case of EnclosedCirc . | |
Standard_EXPORT Standard_Boolean | IsDone () const |
This method returns true when there is a solution and false in the other cases. . | |
Standard_EXPORT Standard_Integer | NbSolutions () const |
This method returns the number of solutions. Raises NotDone if the construction algorithm didn't succeed. . | |
Standard_EXPORT gp_Lin2d | ThisSolution (const Standard_Integer Index) const |
Returns the solution number Index and raises OutOfRange exception if Index is greater than the number of solutions. Be carefull: the Index is only a way to get all the solutions, but is not associated to theses outside the context of the algorithm-object. Raises OutOfRange is raised if Index is greater than the number of solutions. It raises NotDone if the algorithm failed. . | |
Standard_EXPORT void | WhichQualifier (const Standard_Integer Index, GccEnt_Position &Qualif1, GccEnt_Position &Qualif2) const |
Returns the qualifiers Qualif1 and Qualif2 of the tangency arguments for the solution of index Index computed by this algorithm. The returned qualifiers are: - those specified at the start of construction when the solutions are defined as enclosing or outside with respect to the arguments, or - those computed during construction (i.e. enclosing or outside) when the solutions are defined as unqualified with respect to the arguments, or - GccEnt_noqualifier if the tangency argument is a point. Exceptions Standard_OutOfRange if Index is less than zero or greater than the number of solutions computed by this algorithm. StdFail_NotDone if the construction fails. . | |
Standard_EXPORT void | Tangency1 (const Standard_Integer Index, Standard_Real &ParSol, Standard_Real &ParArg, gp_Pnt2d &PntSol) const |
Returns informations about the tangency point between the result number Index and the first argument. ParSol is the intrinsic parameter of the point PntSol on the solution curv. ParArg is the intrinsic parameter of the point PntSol on the argument curv. Raises OutOfRange is raised if Index is greater than the number of solutions. It raises NotDone if the algorithm failed. . | |
Standard_EXPORT void | Tangency2 (const Standard_Integer Index, Standard_Real &ParSol, Standard_Real &ParArg, gp_Pnt2d &PntSol) const |
Returns informations about the tangency point between the result number Index and the second argument. ParSol is the intrinsic parameter of the point ParSol on the solution curv. ParArg is the intrinsic parameter of the point PntSol on the argument curv. Raises OutOfRange is raised if Index is greater than the number of solutions. It raises NotDone if the algorithm failed. . | |
