Static Public Member Functions

static DEFINE_STANDARD_ALLOC gp_Pnt Value3d (const IntSurf_PathPoint &PStart)
 Returns the 3d coordinates of the starting point.

static void Value2d (const IntSurf_PathPoint &PStart, Standard_Real &U, Standard_Real &V)
 Returns the <U, V> parameters which are associated
with.
static Standard_Boolean IsPassingPnt (const IntSurf_PathPoint &PStart)
 Returns True if the point is a point on a non-oriented
arc, which means that the intersection line does not
stop at such a point but just go through such a point.
IsPassingPnt is True when IsOnArc is True

static Standard_Boolean IsTangent (const IntSurf_PathPoint &PStart)
 Returns True if the surfaces are tangent at this point.
IsTangent can be True when IsOnArc is True
if IsPassingPnt is True and IsTangent is True,this point
is a stopped point.

static gp_Vec Direction3d (const IntSurf_PathPoint &PStart)
 returns the tangent at the intersection in 3d space
associated to
static gp_Dir2d Direction2d (const IntSurf_PathPoint &PStart)
 returns the tangent at the intersection in the
parametric space of the parametrized surface.This tangent
is associated to the value2d
la tangente a un sens signifiant (indique le sens de chemin
ement)
an exception is raised if IsTangent is true.

static Standard_Integer Multiplicity (const IntSurf_PathPoint &PStart)
 Returns the multiplicity of the point i-e
the number of auxillar parameters associated to the
point which the principal parameters are given by Value2d

static void Parameters (const IntSurf_PathPoint &PStart, const Standard_Integer Mult, Standard_Real &U, Standard_Real &V)
 Parametric coordinates associated to the multiplicity.
An exception is raised if Mult<=0 or Mult>multiplicity.

an exception is raised if IsTangent is true.


it's the parameters which start the marching algorithm
