class Transition from IntRes2d
|
|

|
inherits Storable from Standard
|
|
|
|
---Purpose: Definition of the type of transition near an
|
|
-- intersection point between two curves. The transition
|
|
-- is either a "true transition", which means that one of
|
|
-- the curves goes inside or outside the area defined by
|
|
-- the other curve near the intersection, or a "touch
|
|
-- transition" which means that the first curve does not
|
|
-- cross the other one, or an "undecided" transition,
|
|
-- which means that the curves are superposed.

TransitionType(me)
|
|
|
|
---Purpose: 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.

Situation(me)
|
|
|
|
---Purpose: returns a significant value if TransitionType returns
|
|
-- TOUCH. In this case, the function returns :
|
|
-- INSIDE 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.

|
---Purpose: returns a significant value if TransitionType
|
|
-- returns TOUCH. In this case, the function returns
|
|
-- true when the 2 curves locally define two
|
|
-- different parts of the space. If TransitionType
|
|
-- returns IN or OUT or UNDECIDED, the exception
|
|
-- DomainError is raised.
