OCC.IntCurvesFace module

This package provide algorithms to compute the intersection pointsbetween a Face [a Shape] and a set of curves (The face [shape] isloaded, then for each curve is given to compute the intersection).Intersector [ ShapeIntersector ] can be used when the caller haveto intersect more than one curve with the face [the shape].If there is only one curve, or if the face has no restrictions,someother algorithms can be called.see for example the packages :** BRepIntCurveSurface : ( One Curve <-> One Shape )** IntCurveSurface : ( One Curve <-> One Surface)

class IntCurvesFace_Intersector(*args)

Bases: object

  • Load a Face. //! The Tolerance <Tol> is used to determine if the first point of the segment is near the face. In that case, the parameter of the intersection point on the line can be a negative value (greater than -Tol).
Parameters:
  • F (TopoDS_Face &) –
  • aTol (float) –
Return type:

None
Bounding()
Return type:Bnd_Box
ClassifyUVPoint()
Parameters:Puv (gp_Pnt2d) –
Return type:TopAbs_State
Destroy()
Return type:None
Face()
  • Returns the significant face used to determine the intersection.
Return type:TopoDS_Face
IsDone()
  • True is returned when the intersection have been computed.
Return type:bool
NbPnt()
Return type:int
Perform()
  • Perform the intersection between the segment L and the loaded face. //! PInf is the smallest parameter on the line PSup is the highest parmaeter on the line //! For an infinite line PInf and PSup can be +/- RealLast.
Parameters:
Return type:

None
  • same method for a HCurve from Adaptor3d. PInf an PSup can also be - and + INF.
Parameters:
  • HCu (Handle_Adaptor3d_HCurve &) –

None
Pnt()
  • Returns the geometric point of the ith intersection between the line and the surface.
Parameters:I (int) –
Return type:gp_Pnt
State()
  • Returns the ith state of the point on the face. The values can be either TopAbs_IN ( the point is in the face) or TopAbs_ON ( the point is on a boudary of the face).
Parameters:I (int) –
Return type:TopAbs_State
SurfaceType()
  • Return the surface type
Return type:GeomAbs_SurfaceType
Transition()
  • Returns the ith transition of the line on the surface.
Parameters:I (int) –
Return type:IntCurveSurface_TransitionOnCurve
UParameter()
  • Returns the U parameter of the ith intersection point on the surface.
Parameters:I (int) –
Return type:float
VParameter()
  • Returns the V parameter of the ith intersection point on the surface.
Parameters:I (int) –
Return type:float
WParameter()
  • Returns the parameter of the ith intersection point on the line.
Parameters:I (int) –
Return type:float
