 Select3D_SensitiveTriangulation (const Handle< SelectMgr_EntityOwner > &theOwnerId, const Handle< Poly_Triangulation > &theTrg, const TopLoc_Location &theInitLoc, const Standard_Boolean theIsInterior=Standard_True)
 Constructs a sensitive triangulation object defined by the owner theOwnerId, the triangulation theTrg, the location theInitLoc, and the flag theIsInterior. More...
 
 Select3D_SensitiveTriangulation (const Handle< SelectMgr_EntityOwner > &theOwnerId, const Handle< Poly_Triangulation > &theTrg, const TopLoc_Location &theInitLoc, const Handle< TColStd_HArray1OfInteger > &theFreeEdges, const gp_Pnt &theCOG, const Standard_Boolean theIsInterior)
 Constructs a sensitive triangulation object defined by the owner theOwnerId, the triangulation theTrg, the location theInitLoc, the array of free edges theFreeEdges, the center of gravity theCOG, and the flag theIsInterior. As free edges and the center of gravity do not have to be computed later, this syntax reduces computation time. More...

Handle< Select3D_SensitiveEntityGetConnected () override
 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.
