Functions
int	tracks3d (const char *fileListPath="/home/igor/data.cache/Run9compare/rc_aln.run_Top_9555_ev0_p0.lst", Int_t tracksToDraw=100, Int_t maxTracks=0)
	Draw a uniformly random sample of tracks as 3D polylines through their hits.

Function Documentation

tracks3d()

int tracks3d	(	const char *	fileListPath = "/home/igor/data.cache/Run9compare/rc_aln.run_Top_9555_ev0_p0.lst",
		Int_t	tracksToDraw = 100,
		Int_t	maxTracks = 0 )

Tracks and hits are read through BmnRootIterator with the aligner's default filters, so the sample comes from exactly the tracks the aligner would use. Reservoir sampling makes it exact in size and uniform over all accepted tracks, at the cost of one full pass over the data. As in BmnAlignReport::Draw(), x and z are swapped: the beam runs along the horizontal axis of the view.

Parameters

fileListPath	text file listing the .root files, '#' lines are ignored
tracksToDraw	size of the sample
maxTracks	sample among the first maxTracks accepted tracks only, 0 for all

Returns

0 on success, -1 if nothing could be read
