[Radiance-general] error no valid view specified

[J. Alstan Jakubiec]

Hello  Nithya,

Just to add to this, you can specify the view inline with the evalglare  
command using the latest 1.11 version,
> -vtt -vv vertangle -vh horzangle
or by referencing a viewfile,
> -vf viewfile
If you are using a 180 degree fisheye lens for your image capture, your  
command might look like,

> evalglare -vta -vv 180 -vh 180 snewshdr.hdr

Best,
Alstan
