Geom2dGcc_Lin2d2Tan Class Reference

This class implements the algorithms used to
create 2d lines tangent to 2 other elements which
can be circles, curves or points.
More than one argument must be a curve.
Describes functions for building a 2D line:
- tangential to 2 curves, or
- tangential to a curve and passing through a point.
A Lin2d2Tan object provides a framework for:
- defining the construction of 2D line(s),
- implementing the construction algorithm, and
- consulting the result(s).

Standard_EXPORT Geom2dGcc_Lin2d2Tan (const Geom2dGcc_QualifiedCurve &Qualified1, const Geom2dGcc_QualifiedCurve &Qualified2, const Standard_Real Tolang)
 This class implements the algorithms used to create 2d
line tangent to two curves.
Tolang is used to determine the tolerance for the tangency points.
.
Standard_EXPORT Geom2dGcc_Lin2d2Tan (const Geom2dGcc_QualifiedCurve &Qualified1, const gp_Pnt2d &ThePoint, const Standard_Real Tolang)
 This class implements the algorithms used to create 2d
lines passing thrue a point and tangent to a curve.
Tolang is used to determine the tolerance for the tangency points.
.
Standard_EXPORT Geom2dGcc_Lin2d2Tan (const Geom2dGcc_QualifiedCurve &Qualified1, const Geom2dGcc_QualifiedCurve &Qualified2, const Standard_Real Tolang, const Standard_Real Param1, const Standard_Real Param2)
 This class implements the algorithms used to create 2d
line tangent to two curves.
Tolang is used to determine the tolerance for the tangency points.
Param1 is used for the initial guess on the first curve.
Param2 is used for the initial guess on the second curve.
.
Standard_EXPORT Geom2dGcc_Lin2d2Tan (const Geom2dGcc_QualifiedCurve &Qualified1, const gp_Pnt2d &ThePoint, const Standard_Real Tolang, const Standard_Real Param1)
 This class implements the algorithms used to create 2d
lines passing thrue a point and tangent to a curve.
Tolang is used to determine the tolerance for the tangency points.
Param2 is used for the initial guess on the curve.
.
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.R
.
Standard_EXPORT gp_Lin2d ThisSolution (const Standard_Integer Index) const
 Returns a line, representing the solution of index Index computed by this algorithm.
Warning
This indexing simply provides a means of consulting the
solutions. The index values are not associated with
these solutions 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 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 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.
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 Tangency2 (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.
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.
