Public Member Functions | |
| void | Clear () |
| Clears data about loaded shells and performed checks More... | |
| void | LoadShells (const TopoDS_Shape &shape) |
| Adds shells contained in the <shape> to the list of loaded shells More... | |
| Standard_Boolean | CheckOrientedShells (const TopoDS_Shape &shape, const Standard_Boolean alsofree=Standard_False, const Standard_Boolean checkinternaledges=Standard_False) |
Checks if shells fulfill orientation condition, i.e. if each <br>
edge is, either present once (free edge) or twice (connected <br>
edge) but with different orientations (FORWARD/REVERSED) <br>
Edges which do not fulfill these conditions are bad <br>
| |
| Standard_Boolean | IsLoaded (const TopoDS_Shape &shape) const |
| Tells if a shape is loaded (only shells are checked) More... | |
| Standard_Integer | NbLoaded () const |
| Returns the actual number of loaded shapes (i.e. shells) More... | |
| TopoDS_Shape | Loaded (const Standard_Integer num) const |
| Returns a loaded shape specified by its rank number. Returns null shape if <num> is out of range More... | |
| Standard_Boolean | HasBadEdges () const |
| Tells if at least one edge is recorded as bad More... | |
| TopoDS_Compound | BadEdges () const |
| Returns the list of bad edges as a Compound It is empty (not null) if no edge are recorded as bad More... | |
| Standard_Boolean | HasFreeEdges () const |
| Tells if at least one edge is recorded as free (not connected) More... | |
| TopoDS_Compound | FreeEdges () const |
| Returns the list of free (not connected) edges as a Compound It is empty (not null) if no edge are recorded as free More... | |
| Standard_Boolean | HasConnectedEdges () const |
| Tells if at least one edge is connected (shared twice or more) More... | |
This class provides operators to analyze edges orientation
in the shell.
| TopoDS_Compound ShapeAnalysis_Shell::BadEdges | ( | ) | const |
Returns the list of bad edges as a Compound
It is empty (not null) if no edge are recorded as bad
| Standard_Boolean ShapeAnalysis_Shell::CheckOrientedShells | ( | const TopoDS_Shape & | shape, |
| const Standard_Boolean | alsofree = Standard_False, |
||
| const Standard_Boolean | checkinternaledges = Standard_False |
||
| ) |
Checks if shells fulfill orientation condition, i.e. if each <br>
edge is, either present once (free edge) or twice (connected <br>
edge) but with different orientations (FORWARD/REVERSED) <br>
Edges which do not fulfill these conditions are bad <br>
If <alsofree> is True free edges are considered.
Free edges can be queried but are not bad
| void ShapeAnalysis_Shell::Clear | ( | ) |
Clears data about loaded shells and performed checks
| TopoDS_Compound ShapeAnalysis_Shell::FreeEdges | ( | ) | const |
Returns the list of free (not connected) edges as a Compound
It is empty (not null) if no edge are recorded as free
| Standard_Boolean ShapeAnalysis_Shell::HasBadEdges | ( | ) | const |
Tells if at least one edge is recorded as bad
| Standard_Boolean ShapeAnalysis_Shell::HasConnectedEdges | ( | ) | const |
Tells if at least one edge is connected (shared twice or more)
| Standard_Boolean ShapeAnalysis_Shell::HasFreeEdges | ( | ) | const |
Tells if at least one edge is recorded as free (not connected)
| Standard_Boolean ShapeAnalysis_Shell::IsLoaded | ( | const TopoDS_Shape & | shape | ) | const |
Tells if a shape is loaded (only shells are checked)
| TopoDS_Shape ShapeAnalysis_Shell::Loaded | ( | const Standard_Integer | num | ) | const |
Returns a loaded shape specified by its rank number.
Returns null shape if <num> is out of range
| void ShapeAnalysis_Shell::LoadShells | ( | const TopoDS_Shape & | shape | ) |
Adds shells contained in the <shape> to the list of loaded shells
| Standard_Integer ShapeAnalysis_Shell::NbLoaded | ( | ) | const |
Returns the actual number of loaded shapes (i.e. shells)
