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 find glare(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.
