Bases: object

CenterOn3()
  • Returns the center PntSol of the solution of index Index computed by this algorithm. ParArg is the parameter of the point PntSol on the third argument.

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.
Parameters:
  • Index (Standard_Integer) –
  • ParSol (float &) –
  • ParArg (float &) –
  • PntSol (gp_Pnt2d) –
Return type:

None

IsDone()
  • 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.
Return type:bool
NbSolutions()
  • Returns the number of lines, representing solutions computed by this algorithm. Exceptions StdFail_NotDone if the construction fails.
Return type:int
Tangency1()
  • 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.
Parameters:
  • Index (Standard_Integer) –
  • ParSol (float &) –
  • ParArg (float &) –
  • PntSol (gp_Pnt2d) –
Return type:

None

ThisSolution()
  • 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.
Parameters:Index (Standard_Integer) –
Return type:gp_Lin2d
WhichQualifier()
  • 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.
Parameters:
  • Index (Standard_Integer) –
  • Qualif1 (GccEnt_Position &) –
