Detailed Description

Class that ties the digitization modules together and produces the channels.

The drift and masking steps are surface-type agnostic: SurfaceDrift and SurfaceMask each dispatch internally on the surface type (plane / disc / cylinder). The resulting (already-clipped) 2-D segment is fed into the Segmentizer, which steps through the channel grid defined by the supplied BinUtility.

channelize()

Acts::Result< std::vector< Segmentizer::ChannelSegment > > ActsFatras::Channelizer::channelize	(	const Hit &	hit,
		const Acts::Surface &	surface,
		const Acts::GeometryContext &	gctx,
		const Acts::Vector3 &	driftDir,
		const Acts::BinUtility &	segmentation,
		double	thickness,
		double	minRelPerpDrift = 0.001 ) const

Do the geometric channelizing.

Parameters

hit	The hit we want to channelize
surface	the surface on which the hit is
gctx	the Geometry context
driftDir	the drift direction
segmentation	the segmentation of the surface
thickness	the thickness of the surface
minRelPerpDrift	minimum relative perpendicular drift (to avoid numerical instability)

Returns
