GccAna_Circ2d2TanOn Class Reference

Describes functions for building a 2D circle
- tangential to 2 curves, or
- tangential to a curve and passing through a point, or
- passing through 2 points,
and with its center on a curve. For these analytic
algorithms, curves are circles or lines.
A Circ2d2TanOn object provides a framework for:
- defining the construction of 2D circles(s),
- implementing the construction algorithm, and
- consulting the result(s).

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 circles, representing solutions
computed by this algorithm.
Exceptions
StdFail_NotDone if the construction fails.
.
Standard_EXPORT gp_Circ2d 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.
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, 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 enclosed, enclosing or
outside with respect to the arguments, or
- those computed during construction (i.e. enclosed,
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 the 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
ParArg is the intrinsic parameter of the point PntSol on
the first argument. Raises OutOfRange if Index is greater than the number
of solutions and NotDone if IsDone returns false.
.
Standard_EXPORT void Tangency2 (const Standard_Integer Index, Standard_Real &ParSol, Standard_Real &ParArg, gp_Pnt2d &PntSol) const
 Returns the informations about the tangency point between the
result number Index and the second argument.
ParSol is the intrinsic parameter of the point PntSol on
the solution.
ParArg is the intrinsic parameter of the point PntSol on
the second argument. Raises OutOfRange if Index is greater than the number
of solutions and NotDone if IsDone returns false.
.
Standard_EXPORT void CenterOn3 (const Standard_Integer Index, Standard_Real &ParArg, gp_Pnt2d &PntArg) const
 Returns the informations about the center (on the curv) of
the result number Index and the third argument.
ParArg is the intrinsic parameter of the point PntArg on
the third argument.
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 Standard_Boolean IsTheSame1 (const Standard_Integer Index) const
 True if the solution and the first argument are the same
(2 circles).
If R1 is the radius of the first argument and Rsol the radius
of the solution and dist the distance between the two centers,
we concider the two circles are identical if R1+dist-Rsol is
less than Tolerance.
False in the other cases.
Raises OutOfRange if Index is greater than the number
of solutions and NotDone if IsDone returns false.
.
Standard_EXPORT Standard_Boolean IsTheSame2 (const Standard_Integer Index) const
 True if the solution and the second argument are the same
(2 circles).
If R2 is the radius of the second argument and Rsol the radius
of the solution and dist the distance between the two centers,
we concider the two circles are identical if R2+dist-Rsol is
less than Tolerance.
False in the other cases.
Raises OutOfRange if Index is greater than the number
of solutions and NotDone if IsDone returns false.
