This class handles the selection of arbitrary point set with internal type of sensitivity. The main principle is to split the point set given onto planar convex polygons and search for the overlap with one or more of them through traverse of BVH tree.

|
|
virtual Select3D_BndBox3d | BoundingBox () override |
| Returns bounding box of the point set. If location transformation is set, it will be applied. 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 () |

Standard_Integer | GetLeafNodeSize () const |
| Returns a number of nodes in 1 BVH leaf. More...
|
|
virtual Handle< Select3D_SensitiveEntity > | GetConnected () |
| 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 | HasInitLocation () const override |
| 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...
|
|
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...

| Standard_Transient (const Standard_Transient &) |
| Copy constructor – does nothing. More...
|
|
Standard_Transient & | operator= (const Standard_Transient &) |
