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.
