.SH EXAMPLE |
| 141 |
|
To calculate the glare sources in the image "scene.pic": |
| 142 |
|
.IP "" .2i |
| 143 |
< |
findglare -p scene.pic > scene.glr |
| 143 |
> |
findglare \-p scene.pic > scene.glr |
| 144 |

|
To compute the Guth visual comfort probability from this result: |
| 146 |
|
.IP "" .2i |
| 147 |
< |
glarendx -t guth_vcp scene.glr |
| 147 |
> |
glarendx \-t guth_vcp scene.glr |

.PP |

|
To compute the glare for a set of angles around the view "good.vp" |
| 150 |
|
from the octree "scene.oct" using an ambient level of .1: |
| 151 |
|
.IP "" .2i |
| 152 |
< |
findglare -vf good.vp -ga 10-60:10 -av .1 .1 .1 scene.oct > scene.glr |

findglare \-vf good.vp \-ga 10-60:10 \-av .1 .1 .1 scene.oct > scene.glr |
