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. More... | |
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. More... | |

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. More... | |
virtual Standard_Boolean | Matches (const SelectBasics_PickArgs &thePickArgs, Standard_Real &theMatchDMin, Standard_Real &theMatchDepth) |
Checks whether the sensitive entity matches the picking detection area (close to the picking line). For details please refer to base class declaration. More... | |
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. More... | |
