Select3D_SensitiveSegment Class Reference

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 ...
