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.
