◆ BoundingBox()

virtual Select3D_BndBox3d MeshVS_SensitivePolyhedron::BoundingBox ( )
overridevirtual

Returns bounding box of a sensitive with transformation applied.

Implements Select3D_SensitiveEntity.

◆ CenterOfGeometry()

virtual gp_Pnt MeshVS_SensitivePolyhedron::CenterOfGeometry ( ) const
overridevirtual

Returns center of a sensitive with transformation applied.

Implements Select3D_SensitiveEntity.

◆ GetConnected()

virtual Handle< Select3D_SensitiveEntity > MeshVS_SensitivePolyhedron::GetConnected ( )
overridevirtual

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.

Reimplemented from Select3D_SensitiveEntity.

◆ Matches()
