This file is foreseen for the Geometry module to replace Extent


this is foreseen for the ‘Geometry’ module

class ITrackingVolumeBuilder
#include <Acts/Geometry/ITrackingVolumeBuilder.hpp>

Interface class ITrackingVolumeBuilders.

this returns the sub-detector tracking volume that is wrapped by the next outer one in the TrackingGeometry building process

If an innerVolume is given, this is wrapped If a VolumeBounds object is given this defines the maximum extent.

Subclassed by Acts::CuboidVolumeBuilder, Acts::CylinderVolumeBuilder

ITrackingVolumeBuilder interface method.

  • gctx – is the geometry context for witch the volume is built

  • oppositeVolume – is an (optional) volume to be wrapped

  • outsideBounds – is an (optional) outside confinement
