ShapeAnalysis_WireOrder () | |
Empty constructor. More... | |
ShapeAnalysis_WireOrder (const Standard_Boolean theMode3D, const Standard_Real theTolerance, const Standard_Boolean theModeBoth=Standard_False) | |
Creates a WireOrder. Flag <theMode3D> defines 3D or 2d mode. Flag <theModeBoth> defines miscible mode and the flag <theMode3D> is ignored. Warning: Parameter <theTolerance> is not used in algorithm. More... | |
void | SetMode (const Standard_Boolean theMode3D, const Standard_Real theTolerance, const Standard_Boolean theModeBoth=Standard_False) |
Sets new values. Clears the edge list if the mode (<theMode3D> or <theModeBoth> ) changes. Clears the connexion list. Warning: Parameter <theTolerance> is not used in algorithm. More... | |
Standard_Real | Tolerance () const |
Returns the working tolerance. More... | |
void | Clear () |

Returns the status of the order (0 if not done) : 0 : all edges are direct and in sequence 1 : all edges are direct but some are not in sequence -1 : some edges are reversed, but no gap remain 3 : edges in sequence are just shifted in forward or reverse manner. More... | |
Standard_Integer | Ordered (const Standard_Integer theIdx) const |
Returns the number of original edge which correspond to the newly ordered number <n> Warning : the returned value is NEGATIVE if edge should be reversed. More... | |

void | Chain (const Standard_Integer num, Standard_Integer &n1, Standard_Integer &n2) const |
Returns, for the chain n0 num, starting and ending numbers of edges. In the list of ordered edges (see Ordered for originals) More... | |
void | SetCouples (const Standard_Real gap) |
Determines the couples of edges for which end and start fit inside a given gap. Queried by NbCouples and Couple Warning: function isn't implemented. More... | |
Standard_Integer | NbCouples () const |
Returns the count of computed couples. More... | |
void | Couple (const Standard_Integer num, Standard_Integer &n1, Standard_Integer &n2) const |
Returns, for the couple n0 num, the two implied edges In the list of ordered edges. More... | |
This class is intended to control and, if possible, redefine the order of a list of edges which define a wire Edges are not given directly, but as their bounds (start,end)
This allows to use this tool, either on existing wire, or on data just taken from a file (coordinates are easy to get)
It can work, either in 2D, or in 3D, or miscible mode The tolerance for each mode is fixed
Two phases : firstly add the couples (start, end) secondly perform then get the result
