Standard_EXPORT | Geom2dGcc_Lin2dTanObl (const Geom2dGcc_QualifiedCurve &Qualified1, const gp_Lin2d &TheLin, const Standard_Real TolAng, const Standard_Real Angle) |
This class implements the algorithm used to create 2d line tangent to a curve and doing an angle Angle with the line TheLin. Angle must be in Radian. Tolang is the angular tolerance. . | |
Standard_EXPORT | Geom2dGcc_Lin2dTanObl (const Geom2dGcc_QualifiedCurve &Qualified1, const gp_Lin2d &TheLin, const Standard_Real TolAng, const Standard_Real Param1, const Standard_Real Angle) |
This class implements the algorithm used to create 2d line tangent to a curve and doing an angle Angle with the line TheLin. Angle must be in Radian. Param2 is the initial guess on the curve QualifiedCurv. Tolang is the angular tolerance. Warning An iterative algorithm is used if Qualified1 is more complex than a line or a circle. In such cases, the algorithm constructs only one solution. Exceptions GccEnt_BadQualifier if a qualifier is inconsistent with the argument it qualifies (for example, enclosed for a circle). . | |
Standard_EXPORT Standard_Boolean | IsDone () const |
Returns true if the construction algorithm does not fail (even if it finds no solution). Note: IsDone protects against a failure arising from a more internal intersection algorithm, which has reached its numeric limits. . | |
Standard_EXPORT Standard_Integer | NbSolutions () const |
Returns the number of lines, representing solutions computed by this algorithm. Exceptions StdFail_NotDone if the construction fails. . | |
Standard_EXPORT gp_Lin2d | ThisSolution (const Standard_Integer Index) const |
Returns a line, representing the solution of index Index computed by this algorithm. 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 | WhichQualifier (const Standard_Integer Index, GccEnt_Position &Qualif1) const |
Returns the qualifier Qualif1 of the tangency argument for the solution of index Index computed by this algorithm. The returned qualifier is: - that specified at the start of construction when the solutions are defined as enclosing or outside with respect to the argument, or - that computed during construction (i.e. enclosing or outside) when the solutions are defined as unqualified with respect to the argument, 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 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. . | |
Standard_EXPORT void | Intersection2 (const Standard_Integer Index, Standard_Real &ParSol, Standard_Real &ParArg, gp_Pnt2d &PntSol) const |
Returns the point of intersection PntSol between the solution of index Index and the second argument (the line) of this algorithm. ParSol is the parameter of the point PntSol on the solution. ParArg is the parameter of the point PntSol on the second argument (the line). Exceptions StdFail_NotDone if the construction fails. GccIter_IsParallel if the solution and the second argument (the line) are parallel. Standard_OutOfRange if Index is less than zero or greater than the number of solutions computed by this algorithm. . | |
Standard_EXPORT Standard_Boolean | IsParallel2 () const |
Returns true if the line and the solution are parallel. This is the case when the angle given at the time of construction is equal to 0 or Pi. Exceptions StdFail_NotDone if the construction fails. . | |
