TopTrans_CurveTransition Class Reference

This algorithm is used to compute the transition
of a Curve intersecting a curvilinear boundary.

The geometric elements are described locally at
the intersection point by a second order
development.

The curve is described by the intersection point,
the tangent vector and the curvature.

The boundary is described by a set of curve
elements, a curve element is either :

DEFINE_STANDARD_ALLOC TopTrans_CurveTransition ()
 Create an empty Curve Transition.

void Reset (const gp_Dir &Tgt, const gp_Dir &Norm, const Standard_Real Curv)
 Initialize a Transition with the local description
of a Curve.

void Reset (const gp_Dir &Tgt)
 Initialize a Transition with the local description
of a straigth line.

void Compare (const Standard_Real Tole, const gp_Dir &Tang, const gp_Dir &Norm, const Standard_Real Curv, const TopAbs_Orientation S, const TopAbs_Orientation Or)
 Add a curve element to the boundary. If Or is
REVERSED the curve is before the intersection,
else if Or is FORWARD the curv is after the
intersection and if Or is INTERNAL the
intersection is in the middle of the curv.

TopAbs_State StateBefore () const
 returns the state of the curve before the
intersection, this is the position relative to the
boundary of a point very close to the intersection
on the negative side of the tangent.

TopAbs_State StateAfter () const
 returns the state of the curve after the
intersection, this is the position relative to the
boundary of a point very close to the intersection
on the positive side of the tangent.
