• Returns True when the 2 curves are tangent at the intersection point. Theexception DomainError is raised if the type of transition is UNDECIDED.

  rtype

  bool

Situation()

• returns a significant value if TransitionType returns TOUCH. In this case, the function returnsINSIDE when the curve remains inside the other one, OUTSIDE when it remains outside the other one, UNKNOWN when the calculus, based on the second derivatives cannot give the result. If TransitionType returns IN or OUT or UNDECIDED, the exception DomainError is raised.

  rtype

  IntRes2d_Situation

TransitionType()

• Returns the type of transition at the intersection. It may be IN or OUT or TOUCH, or UNDECIDED if the two first derivatives are not enough to give the tangent to one of the two curves.
