[Radiance-general] findglare problems

[Greg Ward]

Hi Clarence,

I would have to see the output of findglare #2 to tell you why DGI values were "nan."

As for #1, rcontrib doesn't put the view in its output, so you should add it back with:

	getinfo -a "`cat fisheye.vf`" < fisheye.hdr > fisheye1.hdr

then use "fisheye1.hdr" in your findglare command.

Best,
-Greg
