21 class Loop3d from NMTAlgo
23 ---Purpose: Builds the shells from a set of faces.
24 -- Provides methods for comparing faces mutual
29 MapOfOrientedShape from TopTools,
30 IndexedDataMapOfShapeListOfShape from TopTools,
33 ListOfShape from TopTools,
39 returns Loop3d from NMTAlgo ;
41 AddConstFaces (me:out;
42 S : Shape from TopoDS)
43 ---Purpose: Add faces of <S> as unique faces in the result.
46 AddSectionFaces (me:out;
47 S : Shape from TopoDS)
48 ---Purpose: Add faces of <S> as double faces in the result.
52 AvoidFacesMap : MapOfOrientedShape from TopTools)
53 returns ListOfShape from TopTools is static;
54 ---Purpose: Make and return shells.
55 -- <AvoidFacesMap> can contain faces that must not be
56 -- added to result shells.
57 ---C++: return const &
60 ---Category: class methods
62 IsInside (myclass; E : Edge from TopoDS;
63 F1, F2 : Face from TopoDS;
64 CountDot : Boolean from Standard;
65 Dot : in out Real from Standard;
66 GoodOri : in out Boolean from Standard)
67 returns Boolean from Standard;
68 ---Purpose: check if <F2> is inside <F1> by edge <E>.
69 -- if <CountDot>, compute <Dot>: scalar production of
70 -- normalized vectors pointing inside faces, and
71 -- check if faces are oriented well for sewing
73 Normal (myclass; E : Edge from TopoDS;
80 myNewShells : ListOfShape from TopTools; -- result
82 myFaces : ListOfShape from TopTools;
83 myEFMap : IndexedDataMapOfShapeListOfShape from TopTools;
