A framework to define sensitive zones along a segment
One gives the 3D start and end point;
the maximum number of 2D boxes given
by this entity may be set by the user
if the projected segment is
vertical or horizontal, one needs only 1 box.
for a pi/4 angle -> MaxNumber 2D boxes

Select3D_SensitiveSegment (const Handle< SelectBasics_EntityOwner > &OwnerId, const gp_Pnt &FirstP, const gp_Pnt &LastP, const Standard_Integer MaxRect=1) | |
Constructs the sensitive segment object defined by the owner OwnerId, the points FirstP, LastP and the maximum number of sensitive bounding boxes MaxRect. | |
void | Set (const Standard_Integer MaxRect) |
Sets the maximum number of sensitive rectangles MaxRect. | |
void | StartPoint (const gp_Pnt &aPt) |
changes the start Point of the Segment; | |
void | EndPoint (const gp_Pnt &aPt) |
changes the end point of the segment | |
gp_Pnt | StartPoint () const |
gives the 3D start Point of the Segment | |
gp_Pnt | EndPoint () const |
gives the 3D End Point of the Segment | |
gp_Pnt2d | StartPoint2d () const |
gives the 3D start Point of the Segment | |
gp_Pnt2d | EndPoint2d () const |
gives the 3D End Point of the Segment | |
virtual void | Project (const Handle< Select3D_Projector > &aProjector) |
projection of the sensitive primitive in order to get 2D boxes for the Sort Algorithm | |
void | Areas (SelectBasics_ListOfBox2d &boxes) |
gives the 2D boxes which represent the segment in the selection process... | |
Handle_Select3D_SensitiveEntity | GetConnected (const TopLoc_Location &aLocation) |
Originally this method intended to return sensitive entity with new location aLocation, but currently sensitive entities do not hold a location, instead HasLocation() and Location() methods call corresponding entity owner's methods. Thus all entities returned by GetConnected() share the same location propagated from corresponding selectable object. You must redefine this function for any type of sensitive entity which can accept another connected sensitive entity.//can be connected to another sensitive entity. | |
Standard_Boolean | Matches (const Standard_Real X, const Standard_Real Y, const Standard_Real aTol, Standard_Real &DMin) |
projection of the sensitive primitive in order to get 2D boxes for the Sort Algorithm | |
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. | |
Standard_Integer | MaxBoxes () const |
returns <mymaxrect> | |
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 ... |
