class HInterTool from IntPatch
---Purpose: Tool for the intersection between 2 surfaces.
-- Regroupe pour l instant les methodes hors Adaptor3d...

Pnt from gp
is
-- Pour polyedres
SingularOnUMin(myclass; S:HSurface from Adaptor3d)
returns Boolean from Standard;
---C++: inline
SingularOnUMax(myclass; S:HSurface from Adaptor3d)
returns Boolean from Standard;
---C++: inline
SingularOnVMin(myclass; S:HSurface from Adaptor3d)

returns Boolean from Standard;
---C++: inline
NbSamplesU(myclass; S: HSurface from Adaptor3d; u1,u2: Real from Standard)
returns Integer from Standard;
NbSamplesV(myclass; S: HSurface from Adaptor3d; v1,v2: Real from Standard)
returns Integer from Standard;
-- Methodes pour recherche des points interieurs
NbSamplePoints(myclass; S: HSurface from Adaptor3d)
returns Integer from Standard;

Index: Integer from Standard;
U,V: out Real from Standard);
-- Classify(myclass; S: HSurface from Adaptor3d;
-- U,V: Real from Standard)
--
-- returns State from TopAbs;
-- Methodes sur un arc de restriction
HasBeenSeen(myclass; C: HCurve2d from Adaptor2d)
---Purpose: Returns True if all the intersection point and edges
-- are known on the Arc.
-- The intersection point are given as vertices.
-- The intersection edges are given as intervals between
-- two vertices.
returns Boolean from Standard;
NbSamplesOnArc(myclass; A: HCurve2d from Adaptor2d)
---Purpose: returns the number of points which is used to make
-- a sample on the arc. this number is a function of
-- the Surface and the CurveOnSurface complexity.
returns Integer from Standard;
Bounds(myclass; C: HCurve2d from Adaptor2d;
Ufirst,Ulast: out Real from Standard);
---Purpose: Returns the parametric limits on the arc C.
-- These limits must be finite : they are either
-- the real limits of the arc, for a finite arc,
-- or a bounding box for an infinite arc.
Project(myclass; C: HCurve2d from Adaptor2d;
P: Pnt2d from gp;
Paramproj: out Real from Standard;
Ptproj : out Pnt2d from gp)
---Purpose: Projects the point P on the arc C.
-- If the methods returns Standard_True, the projection is
-- successful, and Paramproj is the parameter on the arc
-- of the projected point, Ptproj is the projected Point.
-- If the method returns Standard_False, Param proj and Ptproj
-- are not significant.
--
returns Boolean from Standard;
-- Methods on a vertex
Tolerance(myclass; V: HVertex from Adaptor3d; C: HCurve2d from Adaptor2d)
---Purpose: Returns the parametric tolerance used to consider
-- that the vertex and another point meet, i-e
-- if Abs(parameter(Vertex) - parameter(OtherPnt))<=
-- Tolerance, the points are "merged".
returns Real from Standard;
Parameter(myclass; V: HVertex from Adaptor3d; C: HCurve2d from Adaptor2d)
---Purpose: Returns the parameter of the vertex V on the arc A.
returns Real from Standard;
-- The following methods are used when HasBeenSeen returns Standard_True
NbPoints(myclass; C: HCurve2d from Adaptor2d)
---Purpose: Returns the number of intersection points on the arc A.
returns Integer from Standard;
Value(myclass; C: HCurve2d from Adaptor2d; Index: Integer from Standard;
Pt: out Pnt from gp; Tol: out Real from Standard;
U: out Real from Standard);
---Purpose: Returns the value (Pt), the tolerance (Tol), and
-- the parameter (U) on the arc A , of the intersection
-- point of range Index.
IsVertex(myclass; C: HCurve2d from Adaptor2d;
Index: Integer from Standard)
---Purpose: Returns True if the intersection point of range Index
-- corresponds with a vertex on the arc A.
returns Boolean from Standard;
Vertex(myclass; C: HCurve2d from Adaptor2d; Index: Integer from Standard;
V: out HVertex from Adaptor3d);
---Purpose: When IsVertex returns True, this method returns the
-- vertex on the arc A.
NbSegments(myclass; C: HCurve2d from Adaptor2d)
---Purpose: returns the number of part of A solution of the
-- of intersection problem.
returns Integer from Standard;
HasFirstPoint(myclass; C: HCurve2d from Adaptor2d;
Index: Integer from Standard;
IndFirst: out Integer from Standard)
---Purpose: Returns True when the segment of range Index is not
-- open at the left side. In that case, IndFirst is the
-- range in the list intersection points (see NbPoints)
-- of the one which defines the left bound of the segment.
-- Otherwise, the method has to return False, and IndFirst
-- has no meaning.
returns Boolean from Standard;
HasLastPoint(myclass; C: HCurve2d from Adaptor2d;
Index: Integer from Standard;
IndLast: out Integer from Standard)
---Purpose: Returns True when the segment of range Index is not
-- open at the right side. In that case, IndLast is the
-- range in the list intersection points (see NbPoints)
-- of the one which defines the right bound of the segment.
-- Otherwise, the method has to return False, and IndLast
-- has no meaning.
returns Boolean from Standard;
IsAllSolution(myclass; C: HCurve2d from Adaptor2d)
---Purpose: Returns True when the whole restriction is solution
-- of the intersection problem.
returns Boolean from Standard;
