Select3D_SensitiveFace Class Reference

Sensitive Entity to make a face selectable.
In some cases this class can raise Standard_ConstructionError and
Standard_OutOfRange exceptions. For more details see Select3D_SensitivePoly.

 Select3D_SensitiveFace (const Handle< SelectBasics_EntityOwner > &OwnerId, const TColgp_Array1OfPnt &ThePoints, const Select3D_TypeOfSensitivity Sensitivity=Select3D_TOS_INTERIOR)
 Constructs a sensitive face object defined by the
owner OwnerId, the array of points ThePoints, and
the sensitivity type Sensitivity.
The array of points is the outer polygon of the geometric face.

 Select3D_SensitiveFace (const Handle< SelectBasics_EntityOwner > &OwnerId, const Handle< TColgp_HArray1OfPnt > &ThePoints, const Select3D_TypeOfSensitivity Sensitivity=Select3D_TOS_INTERIOR)
 Constructs a sensitive face object defined by the
owner OwnerId, the array of points ThePoints, and
the sensitivity type Sensitivity.
The array of points is the outer polygon of the geometric face.

virtual Standard_Boolean Matches (const Standard_Real X, const Standard_Real Y, const Standard_Real aTol, Standard_Real &DMin)
 Matches the coordinates X, Y with the entity found at
that point within the tolerance aTol and the minimum depth DMin.
You must redefine this function for every inheriting entity.
You will have to call this framework inside the redefined function.

virtual Standard_Boolean Matches (const Standard_Real XMin, const Standard_Real YMin, const Standard_Real XMax, const Standard_Real YMax, const Standard_Real aTol)
 Matches the box defined by the coordinates Xmin,
Ymin, Xmax, Ymax with the entity found at that point
within the tolerance aTol.
Xmin, YMin define the minimum point in the lower left
hand corner of the box, and XMax, YMax define the
maximum point in the upper right hand corner of the box.
You must redefine this function for every inheriting entity.
You will have to call this framework inside the redefined function.

virtual Standard_Boolean Matches (const TColgp_Array1OfPnt2d &Polyline, const Bnd_Box2d &aBox, const Standard_Real aTol)
 prevents from hiding virtual methods...

virtual Standard_Real ComputeDepth (const gp_Lin &EyeLine) const
 Computes the depth values for all 3D points defining this face and returns
the minimal value among them.
If the "minimal depth" approach is not suitable and gives wrong detection results
in some particular case, a custom sensitive face class can be implemented at application level
that overrides default ComputeDepth() behavior.

virtual void Dump (Standard_OStream &S, const Standard_Boolean FullDump=Standard_True) const
 2 options :
<FullDump> = False -> general information
<FullDump> = True -> whole informtion 3D +2d ...
