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.
