class Inter2d from Partition
---Purpose: Computes the intersections between edges on a face
-- stores result is SD as AsDes from BRepAlgo.
uses
AsDes from BRepAlgo,
Edge from TopoDS,
Face from TopoDS,
Vertex from TopoDS,
MapOfShape from TopTools,
Real from Standard,
ListOfShape from TopTools
is
CompletPart2d(myclass ; AsDes : mutable AsDes from BRepAlgo;
F : Face from TopoDS;
NewEdges : MapOfShape from TopTools);
---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;
E : Edge from TopoDS;
First : out Boolean 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)
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.
