Member Function Documentation

◆ BoundingBox()

virtual Select3D_BndBox3d Select3D_SensitiveSegment::BoundingBox ( )
overridevirtual

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

Implements Select3D_SensitiveEntity.

◆ CenterOfGeometry()

virtual gp_Pnt Select3D_SensitiveSegment::CenterOfGeometry ( ) const
overridevirtual

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

Implements Select3D_SensitiveEntity.

◆ DumpJson()

virtual void Select3D_SensitiveSegment::DumpJson ( Standard_OStream theOStream,
Standard_Integer  theDepth = -1 
) const
overridevirtual

Dumps the content of me into the stream.

Reimplemented from Select3D_SensitiveEntity.

◆ EndPoint() [1/2]

const gp_Pnt& Select3D_SensitiveSegment::EndPoint ( ) const
inline

gives the 3D End Point of the Segment

◆ EndPoint() [2/2]

inline

changes the end point of the segment

◆ GetConnected()

virtual Handle< Select3D_SensitiveEntity > Select3D_SensitiveSegment::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.

Reimplemented from Select3D_SensitiveEntity.

◆ Matches()

virtual Standard_Boolean Select3D_SensitiveSegment::Matches ( SelectBasics_SelectingVolumeManager theMgr,
SelectBasics_PickResult thePickResult

void Select3D_SensitiveSegment::SetEndPoint ( const gp_Pnt thePnt)
inline

changes the end point of the segment

◆ SetStartPoint()

void Select3D_SensitiveSegment::SetStartPoint ( const gp_Pnt thePnt)
inline

changes the start Point of the Segment;

◆ StartPoint() [1/2]

const gp_Pnt& Select3D_SensitiveSegment::StartPoint ( ) const
inline

gives the 3D start Point of the Segment

◆ StartPoint() [2/2]

void Select3D_SensitiveSegment::StartPoint ( const gp_Pnt thePnt)
inline

changes the start Point of the Segment;

◆ ToBuildBVH()

virtual Standard_Boolean Select3D_SensitiveSegment::ToBuildBVH ( ) const
inlineoverridevirtual

Returns TRUE if BVH tree is in invalidated state.

Reimplemented from Select3D_SensitiveEntity.
