Select3D_SensitiveBox (const Handle< SelectBasics_EntityOwner > &OwnerId, const Bnd_Box &BoundingBox) | |
Constructs a sensitive box object defined by the owner OwnerId, and the bounding box BoundingBox. | |
Select3D_SensitiveBox (const Handle< SelectBasics_EntityOwner > &OwnerId, const Standard_Real XMin, const Standard_Real YMin, const Standard_Real ZMin, const Standard_Real XMax, const Standard_Real YMax, const Standard_Real ZMax) | |
Constructs a sensitive box object defined by the owner OwnerId, and the coordinates Xmin, YMin, ZMin, XMax, YMax, ZMax. Xmin, YMin and ZMin define the minimum point in the front lower left hand corner of the box, and XMax, YMax and ZMax define the maximum point in the back upper right hand corner of the box. | |
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 Box 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) |
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. | |
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 ... | |
const Bnd_Box & | Box () const |
Returns the sensitive 3D box used at the time of construction. |
