| Select3D_SensitiveTriangulation (const Handle< SelectBasics_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< SelectBasics_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...

|
virtual Standard_Integer | NbSubElements () override |
| Returns the amount of nodes in triangulation. More...
|
|
Handle< Select3D_SensitiveEntity > | GetConnected () 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. 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...

| Returns true if the shape corresponding to the entity has init location. More...
|
|
virtual gp_GTrsf | InvInitLocation () const override |
| Returns inversed location transformation matrix if the shape corresponding to this entity has init location set. Otherwise, returns identity matrix. More...

|
| ~Select3D_SensitiveSet () |
|
virtual Standard_Boolean | Matches (SelectBasics_SelectingVolumeManager &theMgr, SelectBasics_PickResult &thePickResult) override |
| Checks whether one or more entities of the set overlap current selecting volume. Implements the traverse of BVH tree built for the set. More...
|
|
virtual void | BVH () override |
| Builds BVH tree for sensitive set. Must be called manually to build BVH tree for any sensitive set in case if its content was initialized not in a constructor, but element by element. More...
|
|
void | MarkDirty () |
| Marks BVH tree of the set as outdated. It will be rebuild at the next call of BVH() More...
|
|
virtual void | Clear () override |
| Destroys cross-reference to avoid memory leak. More...
|
|
Standard_Integer | GetLeafNodeSize () const |
| Returns a number of nodes in 1 BVH leaf. More...
|
|
virtual void | Set (const Handle< SelectBasics_EntityOwner > &theOwnerId) |
| Sets owner of the entity. More...
|
|
const Handle< SelectBasics_EntityOwner > & | OwnerId () const |
| Returns pointer to owner of the entity. More...
|
|
Standard_Integer | SensitivityFactor () const |
| allows a better sensitivity for a specific entity in selection algorithms useful for small sized entities. More...
|
|
void | SetSensitivityFactor (const Standard_Integer theNewSens) |
| Allows to manage sensitivity of a particular sensitive entity. More...
|
|
virtual void | Delete () const override |
| Memory deallocator for transient classes. More...
|
|
Public Member Functions inherited from Standard_Transient |
| Standard_Transient () |
| Empty constructor. More...
|
|
| Standard_Transient (const Standard_Transient &) |
| Copy constructor – does nothing. More...
|
|
Standard_Transient & | operator= (const Standard_Transient &) |
| Assignment operator, needed to avoid copying reference counter. More...
|
|
virtual | ~Standard_Transient () |
| Destructor must be virtual. More...
