# glare(1)

perform glare and visual comfort calculations

## NAME

glare - perform glare and visual comfort calculations

## SYNOPSIS

**glare** \[ **glarefile** \[ **picture** \[ **octree** \] \] \]

## DESCRIPTION

*Glare* is an interactive script for executing programs used to locate glare sources and compute glare indices and visual comfort probability. If no *glarefile* is given, the program prompts the user for a one. If the file does not exist, *glare* asks the user some questions about the scene in question then runs *[findglare(1)](/findglare/1.md)* to compute values to store in the file. *Glare* then presents the user a menu of available glare index calculations. After choosing a calculation, *glare* offers to store the result (usually not useful) or plot the information (but only for multiple glare angles).

If you are creating a new *glarefile,* it usually works best to start with a displayed image for reference during the interrogation.
