Detailed Description

This Mapper takes a (non-const) Geant4 geometry and maps it such that name will be containing the mapping prefix and the Acts::GeometryIdentifier of the surface.

The mapping is done by matching the position of the G4 physical volume with the center position of an Acts::Surface.

This allows to directly associate Geant4 hits to the sensitive elements of the Acts::TrackingGeoemtry w/o map lookup.

void ActsExamples::SensitiveSurfaceMapper::remapSensitiveNames	(	G4VPhysicalVolume *	g4PhysicalVolume,
		const Acts::Transform3 &	motherTransform,
		int &	sCounter
	)		const

Recursive mapping function that walks through the Geant4 hierarchy and applies name remapping to the Physical volumes of the Geant4 geometry.

Parameters

g4PhysicalVolume	the current physical volume in process
motherPosition	the absolute position of the mother
sCounter	a counter of how many volumes have been remapped
