Standard_Boolean | Perform () |
| Builds and analyzes free bounds of the shape.
First calls ShapeAnalysis_FreeBounds for building free
bounds.
Then on each free bound computes its properties:
|
Standard_Boolean | IsLoaded () const |
| Returns True if shape is loaded
|
TopoDS_Shape | Shape () const |
| Returns shape
|
Standard_Real | Tolerance () const |
| Returns tolerance
|
Standard_Integer | NbFreeBounds () const |
| Returns number of free bounds
|
Standard_Integer | NbClosedFreeBounds () const |
| Returns number of closed free bounds
|
Standard_Integer | NbOpenFreeBounds () const |
| Returns number of open free bounds
|
Handle_ShapeAnalysis_HSequenceOfFreeBounds | ClosedFreeBounds () const |
| Returns all closed free bounds
|
Handle_ShapeAnalysis_HSequenceOfFreeBounds | OpenFreeBounds () const |
| Returns all open free bounds
|
Handle_ShapeAnalysis_FreeBoundData | ClosedFreeBound (const Standard_Integer index) const |
| Returns properties of closed free bound specified by its rank
number
|
Handle_ShapeAnalysis_FreeBoundData | OpenFreeBound (const Standard_Integer index) const |
| Returns properties of open free bound specified by its rank
number
|
Standard_Boolean | DispatchBounds () |
Standard_Boolean | CheckContours (const Standard_Real prec=0.0) |
Standard_Boolean | CheckNotches (const Standard_Real prec=0.0) |
Standard_Boolean | CheckNotches (Handle< ShapeAnalysis_FreeBoundData > &fbData, const Standard_Real prec=0.0) |
Standard_Boolean | CheckNotches (const TopoDS_Wire &freebound, const Standard_Integer num, TopoDS_Wire ¬ch, Standard_Real &distMax, const Standard_Real prec=0.0) |
Standard_Boolean | FillProperties (Handle< ShapeAnalysis_FreeBoundData > &fbData, const Standard_Real prec=0.0) |
- calculates area of the contour, <br>
- calculates perimeter of the contour, <br>
- calculates ratio of average length to average width of the <br>
contour, <br>
- estimates average width of contour, <br>
- finds the notches (narrow 'V'-like sub-contour) on the <br>
contour. <br>
For getting free bounds this class uses
ShapeAnalysis_FreeBounds class.
For description of parameters used for initializing this
class refer to CDL of ShapeAnalysis_FreeBounds.
Properties of each contour are stored in the data structure
ShapeAnalysis_FreeBoundData.
