Select3D_SensitiveTriangulation (const Handle< SelectBasics_EntityOwner > &OwnerId, const Handle< Poly_Triangulation > &aTriangulation, const TopLoc_Location &aLoc, const Standard_Boolean InteriorFlag=Standard_True) | |
Constructs a sensitive triangulation object defined by the owner OwnerId, the triangulation aTriangulation, the location aLoc, and the flag InteriorFlag. | |
Select3D_SensitiveTriangulation (const Handle< SelectBasics_EntityOwner > &OwnerId, const Handle< Poly_Triangulation > &aTriangulation, const TopLoc_Location &aLoc, const Handle< TColStd_HArray1OfInteger > &thefreeedges, const gp_Pnt &theCDG, const Standard_Boolean InteriorFlag) | |
Constructs a sensitive triangulation object defined by the owner OwnerId, the triangulation aTriangulation, the location aLoc, the array of free edges thefreeedges, the center of gravity theCDG, and the flag InteriorFlag. As free edges and the center of gravity do not have to be computed later, this syntax reduces computation time. | |
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) |
stores in <boxes> the 2D Boxes which represent the sensitive face in the selection algorithm. | |
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. | |
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 |
give the depht of the last detected triangle (center of gravity) | |
Standard_Integer | DetectedTriangle () const |
Returns the detected three nodes P1, P2, P3 constituting a triangle. This triangle is a component of the overall sensitive triangulation created at construction time. | |
const Handle_Poly_Triangulation & | Triangulation () const |
Returns the triangulation used at the time of construction. | |
const gp_Pnt & | CDG3D () const |
Returns the 3D center of gravity used at the time of construction. | |
const gp_Pnt2d & | CDG2D () const |
Returns the 2D center of gravity used at the time of construction. | |
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) const |
Dmin gives the distance between the cdg and aPoint | |

Standard_Boolean | DetectedTriangle (gp_Pnt &P1, gp_Pnt &P2, gp_Pnt &P3) const |
gives the vertices of detected triangle... | |
Standard_Boolean | DetectedTriangle2d (gp_Pnt2d &P1, gp_Pnt2d &P2, gp_Pnt2d &P3) const |
Gets 2D nodes computed by entity using 3D nodes and viewer parameters (see Project() method) |
