Member Function Documentation

std::vector< double > dd4hep::rec::CellIDPositionConverter::cellDimensions ( const CellID & cell ) const

Returns the segmentation.cellDimensions.

Definition at line 342 of file CellIDPositionConverter.cpp.

References findContext(), and findReadout().

CellID dd4hep::rec::CellIDPositionConverter::cellID ( const Position & global ) const

Return the global cellID for the given global position.

Note: this call is rather slow - only use it when really needed !

Definition at line 87 of file CellIDPositionConverter.cpp.

References _description, std::begin(), and std::end().

const VolumeManagerContext * dd4hep::rec::CellIDPositionConverter::findContext ( const CellID & cellID ) const

Find the context with DetElement, placements etc for a given cellID of a sensitive volume.

Returns NULL if not found (e.g. if the cellID does not correspond to a sensitive volume).

DetElement dd4hep::rec::CellIDPositionConverter::findDetElement	(	const Position &	global,
		const DetElement &	det = `DetElement()`
	)		const

Find the DetElement that contains the given point - if no DetElement is found, an invalid DetElement is returned.

Uses the optionally given DetElement as start for the search.

PlacedVolume dd4hep::rec::CellIDPositionConverter::findPlacement	(	const Position &	point,
		const PlacedVolume &	mother,
		double	locPos[3],
		PlacedVolume::VolIDs &	volIDs
	)		const

Find the lowest daughter Placement in the given Placement that contains the point (in the coordinate system of the mother placement).

Return the local coordinates in this daughter Placement and collect all volIDs on the way.

Definition at line 248 of file CellIDPositionConverter.cpp.

References std::begin(), and std::end().

Readout dd4hep::rec::CellIDPositionConverter::findReadout ( const DetElement & det ) const

Find the readout object for the given DetElement.

If the DetElement is sensitive the corresondig Readout is returned, else a recursive search in the daughter volumes (nodes) of this DetElement's volume is performed and the first Readout object is returned.

Referenced by cellDimensions(), findReadout(), and positionNominal().

Readout dd4hep::rec::CellIDPositionConverter::findReadout ( const PlacedVolume & pv ) const

Return this PlacedVolume's Readout or, if the volume is not sensitive, recursively search for a Readout object in the daughter nodes (volumes).

Position dd4hep::rec::CellIDPositionConverter::position ( const CellID & cellID ) const

Return the global position for a given cellID of a sensitive volume.

Alignment corrections are applied (TO BE DONE). If no sensitive volume is found, (0,0,0) is returned.

Definition at line 32 of file CellIDPositionConverter.cpp.

References positionNominal().

Position dd4hep::rec::CellIDPositionConverter::positionNominal ( const CellID & cellID ) const

Return the nominal global position for a given cellID of a sensitive volume.

No Alignment corrections are applied. If no sensitive volume is found, (0,0,0) is returned.
