Hello everyone, Hello Rob,

I just uninstalled the standard Radiance package I had on my Linux (Debian
Wheezy) machine. This packaged was installed by the standard Add/Remove Software utility in Debian. Then I downloaded "radiance-4.2.a-Linux.tar32.gz" from the NREL's website and copied it's "radiance" folder at /usr/local/. Then I added the RAYPATH in the .bashrc file as per the instructions given on the website. I tried to check the installation by running gensky command, and it works fine. But I have observed some issues with "rvu -o qt" and "objline" :

1. "$ rvu -o qt myScene.oct" gives me this error: rvu:
/lib/i386-linux-gnu/i686/cmov/libc.so.6: version `GLIBC_2.15' not found (required by rvu)

AND

2. "$ objline myScene.rad | x11meta" gives me this error: fatal - cannot open file "/usr/local/lib/meta/vchars.mta", mode "r"

In the previous standard installation of Radiance, "$ objline myScene.rad | x11meta" use to work fine. Do you know what has happened now? and, have I re-installed radiance properly? Thank you!

Regards,
Vaib

Sorry, the second error is not from objline, I meant x11meta there.
Correction.

Hi all,

Does anyone know of a way to get vertical illuminance at a specific point in Radiance?

Thanks,

Hana

Hi,

You can give the direction vector in rtrace command to get irradiance value. Check rtrace manual.
For example: If you assign input arguments "xorg yorg zorg xdir ydir zdir"
as "xorg yorg zorg 0 0 1" then you will get irradiance at the horizontal plane (or floor of the building). Similarly, you can do for other vertical planes by assigning their correct location and direction. To convert irradiance to illuminance, see this command:

$ echo xorg yorg zorg xdir ydir zdir | rtrace -I [options] yourScene.oct | rcalc -e ?$1=$2;$2=179*(.265*$4+.670*$5+.065*$6)?

Regards,
Vaib
