19 ---Purpose: This package describes a Boundary Representation
20 -- Data Structure inherited from the abstract
21 -- Topology defined in the TopoDS package. The
22 -- geometric data are provided by the Geom and Geom2d
25 -- The TVertex, TEdge, and TFace are redefined in
26 -- this package to add geometric information.
29 -- All methods of all classes will be public.
32 MMgt, -- Memory management
33 TCollection, -- Basic data structures
34 TColStd, -- HArray1OfInteger
35 gp, -- Elementary geometry
36 Bnd, -- Bounding boxes
37 TopLoc, -- Local coordinate systems
38 TopAbs, -- Enumerations : Orientation, ShapeType
39 TopoDS, -- Abstract topological data structure
40 GeomAbs, -- Enumerations : Shape
41 Geom, -- 3D geometry : curves and surfaces
42 Geom2d, -- 2D geometry : curves in parametric space
43 Poly -- Triangulations and Polygons
56 -- An Edge is defined by a list of curve representations which
59 -- Geometric representations :
61 -- * A 3d curve (at most one)
63 -- * A curve on surface, curve in parametric space.
65 -- * A curve on closed surface, two curves in parametric space.
67 -- Polygonal representations :
69 -- * A 3d polygon (at most one).
71 -- * A Polygon on triangulation (array of node indices)
73 -- * A Polygon on closed triangulation (2 arrays of node indices)
75 -- * A polygon on surface (array of 2d points in parametric space)
77 -- Curve on 2 surfaces :
79 -- * This is used for storing shape continuity.
