NAME¶

glarendx - calculate glare index

SYNOPSIS¶

glarendx -t type [ -h ] [ glarefile ]

DESCRIPTION¶

Glarendx computes the selected glare index type from the given glarefile produced by findglare(1). Glarendx computes one value for each (indirect illuminance) angle in the input file. If no glarefile is given, glarendx reads from the standard input. The -h option can be used to remove the information header from the output. Glarendx understands the following arguments for type:

	    guth_vcp	Guth Visual Comfort Probability
	     cie_cgi	CIE Glare Index (Einhorn)
	         ugr	Unified Glare Rating
	      brs_gi	BRS Glare Index
	         dgi	Daylight Glare Index
	    guth_dgr	Guth Disability Glare Rating
	    vert_dir	Direct Vertical Illuminance
	    vert_ill	Total Vertical Illuminance
	    vert_ind	Indirect Vertical Illuminance

Alternatively, a symbolic or hard link to the program with any of the above names may be used in place of the type argument.
