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 ... | |
virtual Handle_Select3D_SensitiveEntity | GetConnected (const TopLoc_Location &theLocation) |
Returns the copy of this |
