A framework to define selection of triangles in a view.
This comes into play in the detection of meshing and triangulation in surfaces.
In some cases this class can raise Standard_ConstructionError and
Standard_OutOfRange exceptions. For more details see Select3D_SensitivePoly.

Select3D_SensitiveTriangle (const Handle< SelectBasics_EntityOwner > &OwnerId, const gp_Pnt &P1, const gp_Pnt &P2, const gp_Pnt &P3, const Select3D_TypeOfSensitivity Sensitivity=Select3D_TOS_INTERIOR) | |
Constructs a sensitive triangle object defined by the owner OwnerId, the points P1, P2, P3, and the type of sensitivity Sensitivity. | |
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... | |
Standard_Real | ComputeDepth (const gp_Lin &EyeLine) const |
Returns the depth of this object on the line EyeLine. EyeLine goes through the eye towards a point defined by the coordinates X,Y in the function GetEyeLine. //! gives an abcissa on <aLin> . <aLin> represents the line going through the eye towards an X,Y point on the screen. This Method must return a mean Depth on this line. | |
void | Points3D (gp_Pnt &P1, gp_Pnt &P2, gp_Pnt &P3) const |
Returns the 3D points P1, P2, P3 used at the time of construction. | |
gp_Pnt | Center3D () const |
Returns the center point of the sensitive triangle created at construction time. | |
gp_XY | Center2D () const |
WARNING : the returned Values are the original values without the stored location (if there's one). To get the genuine value, One must apply this location (Method Location() ) | |
Standard_Integer | Status (const Standard_Real X, const Standard_Real Y, const Standard_Real aTol, Standard_Real &Dmin) const |
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 | |

static Standard_Integer | Status (const gp_XY &p0, const gp_XY &p1, const gp_XY &p2, const gp_XY &aPoint, const Standard_Real aTol, Standard_Real &Dmin) |
Dmin gives the distance between the cdg and aPoint return |
