GccAna_Lin2dTanPer (const gp_Pnt2d &ThePnt, const gp_Circ2d &TheCircle) | |
This method implements the algorithms used to create 2d lines passing through a point and perpendicular to a circle. | |
GccAna_Lin2dTanPer (const GccEnt_QualifiedCirc &Qualified1, const gp_Lin2d &TheLin) | |
This method implements the algorithms used to create 2d lines tangent to a circle and perpendicular to a line. | |
GccAna_Lin2dTanPer (const GccEnt_QualifiedCirc &Qualified1, const gp_Circ2d &TheCircle) | |
This method implements the algorithms used to create 2d lines tangent to a circle and perpendicular to a circle. | |
Standard_Boolean | IsDone () const |
Returns True if the algorithm succeeded. | |
Standard_Integer | NbSolutions () const |
Returns the number of solutions. Raises NotDone if the construction algorithm didn't succeed. | |
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: | |
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 careful: the Index is only a way to get all the solutions, but is not associated to those outside the context of the algorithm-object. Raises NotDone if the construction algorithm didn't succeed. It raises OutOfRange if Index is greater than the number of solutions. | |
void | Tangency1 (const Standard_Integer Index, Standard_Real &ParSol, Standard_Real &ParArg, gp_Pnt2d &Pnt) const |
Returns informations about the tangency point between the result number Index and the first argument. ParSol is the intrinsic parameter of the point on the solution curv. ParArg is the intrinsic parameter of the point on the argument curv. If the first argument is a point ParArg is equal zero. raises NotDone if the construction algorithm didn't succeed. It raises OutOfRange if Index is greater than the number of solutions. | |
void | Intersection2 (const Standard_Integer Index, Standard_Real &ParSol, Standard_Real &ParArg, gp_Pnt2d &PntSol) const |
Returns informations about the intersection between the solution number Index and the second argument. It returns the first intersection in a case of Lin2dTanPer which is perpendicular to a circle . ParSol is the intrinsic parameter of the point on the solution curv. ParArg is the intrinsic parameter of the point on the argument curv. Raises NotDone if the construction algorithm didn't succeed. It raises OutOfRange if Index is greater than the number of solutions. |
