GccAna_Lin2dTanPer Class Reference

This class implements the algorithms used to
create 2d lines tangent to a circle or a point and
perpendicular to a line or a circle.
Describes functions for building a 2D line perpendicular
to a line and:
- tangential to a circle, or
- passing through a point.
A Lin2dTanPer object provides a framework for:
- defining the construction of 2D line(s),
- implementing the construction algorithm, and
- consulting the result(s).

Standard_EXPORT GccAna_Lin2dTanPer (const gp_Pnt2d &ThePnt, const gp_Lin2d &TheLin)
 This method implements the algorithms used to
create 2d lines passing through a point and
perpendicular to a line.
.
Standard_EXPORT 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.
.
Standard_EXPORT 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.
.
Standard_EXPORT 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_EXPORT Standard_Boolean IsDone () const
 Returns True if the algorithm succeeded.
.
Standard_EXPORT Standard_Integer NbSolutions () const
 Returns the number of solutions.
Raises NotDone if the construction algorithm didn't succeed.
.
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 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.
.
Standard_EXPORT 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.
.
Standard_EXPORT 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.
