remove from a shape, the internal edges that are
not connected to any face in the shape. We can
get the list of the edges as a
DataMapOfShapeListOfShape with a Face of the Shape
as the key and a list of internal edges as the
value. The list of internal edges means edges
that are not connected to any face in the shape.
Example of use :
TopTools_DataMapOfShapeListOfShape mymap;
TopOpeBRepTool_PurgeInternalEdges
mypurgealgo(mysolid); mypurgealgo.GetFaces(mymap);
#include <TopOpeBRepTool_PurgeInternalEdges.hxx>
Public Member Functions | |
DEFINE_STANDARD_ALLOC | TopOpeBRepTool_PurgeInternalEdges (const TopoDS_Shape &theShape, const Standard_Boolean PerformNow=Standard_True) |
Initialize members and begin exploration of shape depending of the value of PerformNow | |
void | Faces (TopTools_DataMapOfShapeListOfShape &theMapFacLstEdg) |
returns the list internal edges associated with the faces of the myShape. If PerformNow was False when created, then call the private Perform method that do the main job. | |
TopoDS_Shape & | Shape () |
returns myShape modified with the list of internal edges removed from it. | |
const Standard_Integer | NbEdges () const |
returns the number of edges candidate to be removed | |
Standard_Boolean | IsDone () const |
returns False if the list of internal edges has not been extracted | |
void | Perform () |
Using the list of internal edge from each face, rebuild myShape by removing thoses edges. | |
