-
- ---Purpose: Computes the intersections between the edges stored
- -- is AsDes as descendants of <F> . Intersections is computed
- -- between two edges if one of them is bound in NewEdges.

-
- FindEndVertex(myclass; VertList : ListOfShape from TopTools;
- f,l : Real from Standard;

- DU : out Real from Standard)
- returns Vertex from TopoDS;
- ---Purpose: Returns a vertex from <VertList> having parameter on
- -- <E> most close to <f> or <l>. <First> is True if
- -- found vertex is closer to <f>. <DU> returns parameter
- -- difference.
-
- AddVonE(myclass; V : Vertex from TopoDS;
- E1,E2 : Edge from TopoDS;
- AsDes : mutable AsDes from BRepAlgo;
- F: Face from TopoDS)
- returns Vertex from TopoDS;
- ---Purpose: Put V in AsDes as intersection of E1 and E2.
- -- Check that vertex equal to V already exists on one
- -- of edges, in such a case, V is not added but
- -- existing vertex is updated to be on E1 and E2 and
- -- is returned insead of V.
- -- Optional F is a face E1 and E2 are on. If F is
- -- provided, it is used to find new vertices on E1
- -- and E2 resulting from intersection of new edges on
- -- the two other faces the F interferes with and
- -- through which E1 and E2 pass too. This helps to
- -- avoid small edges.
-
-
- GetTolerance(myclass; theV : Vertex from TopoDS;
- theU : Real from Standard;
- theE : Edge from TopoDS;
- theAsDes : AsDes from BRepAlgo)
- returns Real from Standard;
- ---Purpose: Returns tolerance theV must have atfer its
- -- addition to theE with theU parameter. theAsDes is
- -- used to find pcurves of theE

- Create returns Spliter from Partition;
- ---Purpose: constructor
-
- AddShape ( me : in out; S : Shape from TopoDS);
- ---Purpose: add object Shape to be splitted.
- -- If S is a COMPOUND or COMPSOLID, it will be
- -- exploded in order to get more simple object
- -- shapes.
- -- Object shapes that are vertices, edges or wires
- -- won't be splitted and won't be in a result.
-
- AddTool ( me : in out; S : Shape from TopoDS);
- ---Purpose: add cutting tool
-
- Compute (me : in out; Limit : ShapeEnum from TopAbs
- = TopAbs_SHAPE);
- ---Purpose: produce a result which is a compound of parts of
- -- object shapes. A part can be either a vertex,
- -- edge, wire, face, shell or solid.
- -- By default, a part is of the same topology as an
- -- object shape, else <Limit> restricts parts
- -- reconstruction.
- -- If <Limit> == TopAbs_VERTEX, only new vertices are
- -- returned in the result
-
- KeepShapesInside (me : in out; S : Shape from TopoDS);
- ---Purpose: remove shapes that are outside of S from result.
- -- S should be an object shape.
- ---Warning: call it after Compute()
-
- RemoveShapesInside (me : in out; S : Shape from TopoDS);
- ---Purpose: remove shapes that are inside S from result.
- -- S should be an object shape.
- ---Warning: call it after Compute()

- Shape ( me ) returns Shape from TopoDS;
- ---Purpose: return resulting compound

- MakeFaces (me: in out; S : Shape from TopoDS)
- returns Shape from TopoDS is private;

-
- MakeEdges (me;
- E : Edge from TopoDS;
- VOnE : ListOfShape from TopTools;
- NE : in out ListOfShape from TopTools)
- is private;
- ---Purpose: cut E by vertices VOnE, return list of new edges
- -- NE
-
- FindFacesInside (me: in out; S : Shape from TopoDS;
- CheckClosed : Boolean = Standard_False;
- All : Boolean = Standard_False)
- returns Shape from TopoDS is private;
- ---Purpose: return compound of faces of other shapes that are
- -- inside <S>. <S> must have image in myImageShape.
- -- <CheckClosed> makes avoid faces that do not form a
- -- closed shell
- -- <All> makes return already added faces
-
- CheckTool ( me: in out; S : Shape from TopoDS)
- returns Boolean from Standard is private;
- ---Purpose: Return True if <S> is a tool shape. Prepare tool
- -- faces of <S> for the search of internal faces.
-
- MergeEqualEdges (me: in out; LE : ListOfShape from TopTools) is private;
- ---Purpose: among LE, find equal edges, choose ones to keep
- -- and make them have pcurves on all faces they are
- -- shared by
- -- <LE> contains edge splits
-
- IsInside (myclass; S1,S2 : Shape from TopoDS)
- returns Boolean from Standard is private;
- ---Purpose: Return True if the first vertex of S1 inside S2.
- -- If S1.IsNull(), check infinite point against S2.
-
- GetOriginalShape(me; aShape : Shape from TopoDS)
- returns Shape from TopoDS is private;
- ---Purpose: Return the shape aShape originates from. aShape
- -- should be a face or more complex result shape
-
- FindToolsToReconstruct(me: in out) is private;
- ---Purpose: find and store as objects tools which interfere
- -- with solids or are inside solids without
