Detailed Description

Class to be used for gaps in Volumes as a navigational link. Navigation Layers have a surface representation, but should usually never be propagated to.

const Vector3D Acts::NavigationLayer::binningPosition	(	const GeometryContext &	gctx,
		BinningValue	bValue
	)		const

inlinefinalvirtual

The binning position method

Parameters

gctx	The current geometry context object, e.g. alignment
bValue	is the value for which the binning position is requested as default the center is given, but may be overloaded

Returns: The return vector can be used for binning in a TrackingVolume
