Select3D_BndBox3d Select3D_SensitiveTriangulation::applyTransformation ( )

protected

Inner function for transformation application to bounding box of the triangulation.

virtual Select3D_BndBox3d Select3D_SensitiveTriangulation::BoundingBox ( )

virtual

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

Reimplemented from Select3D_SensitiveSet.

virtual Select3D_BndBox3d Select3D_SensitiveTriangulation::Box ( const Standard_Integer theIdx ) const

virtual

Returns bounding box of triangle/edge with index theIdx.

Implements Select3D_SensitiveSet.

virtual Standard_Real Select3D_SensitiveTriangulation::Center	(	const Standard_Integer	theIdx,
		const Standard_Integer	theAxis
	)		const

virtual

Returns geometry center of triangle/edge with index theIdx in array along the given axis theAxis.

Implements Select3D_SensitiveSet.

virtual gp_Pnt Select3D_SensitiveTriangulation::CenterOfGeometry ( ) const

virtual

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

Reimplemented from Select3D_SensitiveSet.

Handle_Select3D_SensitiveEntity Select3D_SensitiveTriangulation::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.
