How to create an 10.000 lux overcast grey sky? #5

Closed redinkinc closed 9 years ago

redinkinc commented 9 years ago

Hello Again, everything works fine so far, but as I now want to get the illuminance in a room I followed the radiance_tutorial and end up in the following problem: When I use the provded sky.rad and create the sky.mat using gensky as described in the tutorial, I result in the following:

$ echo 0 0 0 0 0 1 | rtrace -I -ab 1 octrees\sky.oct

?RADIANCE

oconv skies\sky_10klx.mat skies\sky.rad rtrace -I -ab 1 SOFTWARE= RADIANCE 4.2a lastmod by on w015t-001 CAPDATE= 2015:09:15 11:56:42 GMT= 2015:09:15 09:56:42 FORMAT=ascii 4.751300e+001 5.813355e+001 6.707717e+001

and

echo 0 0 0 0 0 1 | rtrace -I -h -ab 1 octrees\sky.oct | rcalc -e "$1=179(.265$1+.670$2+.065$3)" 10025.4983

This is as near as I can get, but the sky is not grey. Can anyone provide me with an answer? Thanks, Fabian

Hi Fabian, Github is not the best medium to ask such questions. I would suggest you to post them on unmethours.com and tag them as radiance. The right people will be able to get back to you on the list.
