       glarendx - calculate glare index


       glarendx -t type [ -h ] [ glarefile ]


       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.
