◆ curvedToFlat()

constexpr void o2::its3::SegmentationMosaix::curvedToFlat	(	const float	xCurved,
		const float	yCurved,
		float &	xFlat,
		float &	yFlat
	)		const

inlineconstexprnoexcept

Transformation from the curved surface to a flat surface. Additionally a shift in the flat coordinates must be applied because the center of the TGeoShap when projected will be higher than the physical thickness of the chip (we add an additional hull to account for the copper metal interconnection which is in reality part of the chip but in our simulation the silicon and metal layer are separated). Thus we shift the projected center down by this difference to align the coordinate systems.

Parameters

xCurved	Detector local curved coordinate x in cm with respect to the center of the sensitive volume.
yCurved	Detector local curved coordinate y in cm with respect to the center of the sensitive volume.
xFlat	Detector local flat coordinate x in cm with respect to the center of the sensitive volume.
yFlat	Detector local flat coordinate y in cm with respect to the center of the sensitive volume.

◆ detectorToLocal() [1/2]

constexpr bool o2::its3::SegmentationMosaix::detectorToLocal	(	int const	iRow,
		int const	iCol,
		float &	xRow,
		float &	zCol
	)		const

inlineconstexprnoexcept

Transformation from Detector cell coordinates to Geant detector centered local coordinates (cm)

Parameters

int	iRow Detector x cell coordinate.
int	iCol Detector z cell coordinate.
float	x Detector local coordinate x in cm with respect to the center of the sensitive volume.
float	z Detector local coordinate z in cm with respect to the center of the sensitive volume. If iRow and or iCol is outside of the segmentation range a value of -0.5Dx() or -0.5Dz() is returned.

◆ flatToCurved()

constexpr void o2::its3::SegmentationMosaix::flatToCurved	(	float	xFlat,
		float	yFlat,
		float &	xCurved,
		float &	yCurved
	)		const

inlineconstexprnoexcept

Transformation from the flat surface to a curved surface It works only if the detector is not rototraslated.

Parameters

xFlat	Detector local flat coordinate x in cm with respect to the center of the sensitive volume.
yFlat	Detector local flat coordinate y in cm with respect to the center of the sensitive volume.
xCurved	Detector local curved coordinate x in cm with respect to the center of the sensitive volume.
yCurved	Detector local curved coordinate y in cm with respect to the center of the sensitive volume.

◆ localToDetector()

constexpr bool o2::its3::SegmentationMosaix::localToDetector	(	float const	xRow,
		float const	zCol,
		int &	iRow,
		int &	iCol
	)		const

inlineconstexprnoexcept

Transformation from Geant detector centered local coordinates (cm) to Pixel cell numbers iRow and iCol. Returns true if point x,z is inside sensitive volume, false otherwise. A value of -1 for iRow or iCol indicates that this point is outside of the detector segmentation as defined.

Parameters

float	x Detector local coordinate x in cm with respect to the center of the sensitive volume.
float	z Detector local coordinate z in cm with respect to the center of the sensitive volume.
int	iRow Detector x cell coordinate.
int	iCol Detector z cell coordinate.
