23 class Loop3d from NMTAlgo
25 ---Purpose: Builds the shells from a set of faces.
26 -- Provides methods for comparing faces mutual
31 MapOfOrientedShape from TopTools,
32 IndexedDataMapOfShapeListOfShape from TopTools,
35 ListOfShape from TopTools,
41 returns Loop3d from NMTAlgo ;
43 AddConstFaces (me:out;
44 S : Shape from TopoDS)
45 ---Purpose: Add faces of <S> as unique faces in the result.
48 AddSectionFaces (me:out;
49 S : Shape from TopoDS)
50 ---Purpose: Add faces of <S> as double faces in the result.
54 AvoidFacesMap : MapOfOrientedShape from TopTools)
55 returns ListOfShape from TopTools is static;
56 ---Purpose: Make and return shells.
57 -- <AvoidFacesMap> can contain faces that must not be
58 -- added to result shells.
59 ---C++: return const &
62 ---Category: class methods
64 IsInside (myclass; E : Edge from TopoDS;
65 F1, F2 : Face from TopoDS;
66 CountDot : Boolean from Standard;
67 Dot : in out Real from Standard;
68 GoodOri : in out Boolean from Standard)
69 returns Boolean from Standard;
70 ---Purpose: check if <F2> is inside <F1> by edge <E>.
71 -- if <CountDot>, compute <Dot>: scalar production of
72 -- normalized vectors pointing inside faces, and
73 -- check if faces are oriented well for sewing
75 Normal (myclass; E : Edge from TopoDS;
82 myNewShells : ListOfShape from TopTools; -- result
84 myFaces : ListOfShape from TopTools;
