Detailed Description

Converter from an ACTS TrackingGeometry to a detray detector.

The geometry conversion is a two-step process: first the ACTS geometry is converted into detray payloads by a DetrayPayloadConverter, then those payloads are used to build the actual detray detector. This class drives the second step and lets the call site fully customize the first step by supplying its own configured DetrayPayloadConverter instance through the Config.

Member Function Documentation

convert()

template<typename metadata_t>

DetrayGeometry< metadata_t > ActsPlugins::DetrayGeometryConverter::convert	(	vecmem::memory_resource &	mr,
		const Acts::GeometryContext &	gctx,
		const std::shared_ptr< const Acts::TrackingGeometry > &	trackingGeometry,
		const std::string &	detectorName = "" ) const

Convert an ACTS TrackingGeometry into a detray detector.

Template Parameters

metadata_t

the detector metadata type to build

Parameters

mr	the memory resource to use for the detray detector construction
gctx	the geometry context
trackingGeometry	the ACTS tracking geometry to convert
detectorName	the name to set for the detray detector (optional, if not set, it will be taken from the payloads or defaulted to empty)

This method performs the following steps:

1. It converts the ACTS tracking geometry into detray payloads using the configured DetrayPayloadConverter.
2. It builds a detray detector from the converted payloads using the detray::detector_builder.

Returns

The built detray detector together with its name map.
