GLARENDX(1)

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.
