Constructor & Destructor Documentation

Acts::TGeoDetectorElement::TGeoDetectorElement	(	const Identifier &	identifier,
		TGeoNode *	tGeoDetElement,
		const TGeoMatrix *	mGlobal = `nullptr`,
		const std::string &	axes = `"XYZ"`,
		double	scalor = `1.`,
		bool	isDisc = `false`,
		std::shared_ptr< const Acts::ISurfaceMaterial >	material = `nullptr`,
		std::shared_ptr< const Acts::DigitizationModule >	digitizationModule = `nullptr`
	)

Constructor

Parameters

identifier	is the detector identifier
tGeoDetElement	is the TGeoNode which should be represented
mGlobal	to global is the (optional) transform applied to the TGeoNode
axes	is the axis orientation with respect to the tracking frame it is a string of the three characters x, y and z (standing for the three axes) there is a distinction between capital and lower case characters : capital -> positive orientation of the axis lower case -> negative orientation of the axis example options are "XYZ" -> identical frame definition (default value) "YZX" -> node y axis is tracking x axis, etc. "XzY" -> negative node z axis is tracking y axis, etc.

Note: This parameter only needs to be set for plane modules

Parameters

scalor	is the scale factor for unit conversion if needed
isDisc	in case the sensitive detector module should be translated as disc (e.g. for endcaps) this flag should be set to true

Note: In the translation from a 3D geometry (TGeo) which only knows tubes to a 2D geometry (Tracking geometry) a distinction if the module should be described as a cylinder or a disc surface needs to be done. Since this information can not be taken just from the geometry description (both can be described as TGeoTubeSeg), one needs to set the flag 'isDisc' in case a volume with shape TGeoTubeSeg should be translated to a disc surface. Per default it will be translated into a cylindrical surface.

Parameters

material	Possible material of detector element
digitizationModule	Shared pointer to the geometric digitization description

Here is the call graph for this function:

Acts::TGeoDetectorElement::TGeoDetectorElement	(	const Identifier &	identifier,
		const TGeoMatrix &	transform,
		TGeoNode *	tGeoDetElement,
		const std::string &	axes = `"XYZ"`,
		double	scalor = `1.`,

		std::shared_ptr< const Acts::DigitizationModule >	digitizationModule = `nullptr`
	)

Alternative Constructor when the localToGlobal transform is already known for the detector element (e.g. usage in DD4hepPlugin)

Parameters

identifier	is the detector identifier
transform	the full transformation matrix of the detector element (local to global)
tGeoDetElement	is the TGeoNode which should be represented
axes	is the axis orientation with respect to the tracking frame it is a string of the three characters x, y and z (standing for the three axes) There is a distinction between capital and lower case characters : capital -> positive orientation of the axis lower case -> negative oriantation of the axis

Example options are:

"XYZ" -> identical frame definition (default value)
"YZX" -> node y axis is tracking x axis, etc.
"XzY" -> negative node z axis is tracking y axis, etc.
Note
This parameter only needs to be set for plane modules

Parameters

scalor is the scale factor for unit conversion if needed

isDisc in case the sensitive detector module should be translated as disc (e.g. for endcaps) this flag should be set to true
