Detailed Description

Shell or set of faces.

A shell is a composite surface formed by finite set of faces MbFace, connected together by edges MbCurveEdge.
In general case a shell may be multiply connected, i.e. it may describe several pairwise not connected surfaces.
A shell is called closed if it has not a boundary, otherwise a shell is called unclosed.
The closedness of a shell indicates the possibility of using of a set of its internal points in operations with solids MbSolid. Formally, a set of faces is not restricted by any conditions, but actually faces of the set satisfy certain conditions. In order to highlight this feature of a shell, the concept "manifold shell" is introduced. Shells which satisfy the below requirements are called manifold.

  1. Shells are finite.
  2. Shells do not intersect themselves.
  3. Shells are two-sided (oriented).
  4. At each edge of a shell not more than two faces are connected. Two faces of shell connected in such way, that the external side of one face turns to the external side of another face.
  5. With any go-round of any vertex of closed shell on its surface, one will visit all faces connected with this vertex of a face and intersect all outgoing edges.
    Since the external side of a face turns to the external side of adjacent face, a manifold shell also has the external and internal sides. A closed manifold shell divides the three-dimensional space into two parts, one of which is located inside the shell. Let closed manifold shell be called external shell, if its external side is directed out from a part of space bounding by the shell.
    Let closed manifold shell be called an internal shell, if its external side is directed inside a part of space bounding by the shell.

Create a copy of a shell with copying of a part of data and moving another part of data from the original to the copy.
The parameter 'history' is used if the copying mode is cm_KeepHistory.

Parameters
[in]sameShell- A way of data transferring when copying of a shell MbeCopyMode:
sameShell == cm_Same - an initial shell is returned as the copy (a shell is not copied but the pointers of edges to the faces are correctly set);
sameShell == cm_KeepHistory - a part of data is copied (the initial shell and its copy have the common basis surfaces and vertices) and the sets of faces of the object 'history' are filled;
sameShell == cm_KeepSurface - a part of data is copied (the initial shell and its copy have the common basis surfaces);
sameShell == cm_Copy - an ordinary copying (the initial shell and its copy have no the common data).
