Detailed Description

A framework to define selection of a wire owner by an elastic wire band.

Constructor & Destructor Documentation

Select3D_SensitiveWire::Select3D_SensitiveWire ( const Handle< SelectBasics_EntityOwner > & theOwnerId )

Constructs a sensitive wire object defined by the owner theOwnerId.

Member Function Documentation

void Select3D_SensitiveWire::Add ( const Handle< Select3D_SensitiveEntity > & theSensitive )

Adds the sensitive entity theSensitive to this framework.

virtual Select3D_BndBox3d Select3D_SensitiveWire::BoundingBox ( )

virtual

Returns bounding box of the wire. If location transformation is set, it will be applied.

Reimplemented from Select3D_SensitiveSet.

virtual Select3D_BndBox3d Select3D_SensitiveWire::Box ( const Standard_Integer theIdx ) const

virtual

Returns bounding box of sensitive entity with index theIdx.

Implements Select3D_SensitiveSet.

virtual Standard_Real Select3D_SensitiveWire::Center	(	const Standard_Integer	theIdx,
		const Standard_Integer	theAxis
	)		const

virtual

Returns geometry center of sensitive entity index theIdx in the vector along the given axis theAxis.

Implements Select3D_SensitiveSet.

virtual gp_Pnt Select3D_SensitiveWire::CenterOfGeometry ( ) const

virtual

Returns center of the wire. If location transformation is set, it will be applied.

Reimplemented from Select3D_SensitiveSet.

virtual Standard_Real Select3D_SensitiveWire::distanceToCOG ( SelectBasics_SelectingVolumeManager & theMgr )

protectedvirtual

Calculates distance from the 3d projection of used-picked screen point to center of the geometry.

Implements Select3D_SensitiveSet.

virtual Standard_Boolean Select3D_SensitiveWire::elementIsInside	(	SelectBasics_SelectingVolumeManager &	theMgr,
		const Standard_Integer	theElemIdx
	)

protectedvirtual

Checks whether the entity with index theIdx is inside the current selecting volume.

Implements Select3D_SensitiveSet.

virtual Handle< Select3D_SensitiveEntity > Select3D_SensitiveWire::GetConnected ( )

virtual

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.

const NCollection_Vector<Handle< Select3D_SensitiveEntity > >& Select3D_SensitiveWire::GetEdges ( )

returns the sensitive edges stored in this wire

Handle_Select3D_SensitiveEntity Select3D_SensitiveWire::GetLastDetected ( ) const

virtual Standard_Integer Select3D_SensitiveWire::NbSubElements ( )

virtual

Returns the amount of sub-entities.

Implements Select3D_SensitiveEntity.
