rtcontrib - rad3R9_linux

Hi Greg,

I just updated my Radiance version by installing the latest one available on
radsite.lbl.gov/radiance (rad3R9). I tried to run rtcontrib, but nothing
happened. Neither an error nor a result, and no processor activity. I didn't
see anything discussing this issue in the archives, so I would be grateful for
your help! Here are a couple of lines describing my attempts:

1) Does my terminal know rtcontrib...:

IN:
augsburg@lenipc24:~$ rtcontrib
OUT:
Usage: rtcontrib [-n nprocs][-V][-r][-e expr][-f source][-o ospec][-b binv] {-m
mod | -M file} [rtrace options] octree

Yes!

2) Is rtcontrib able to compute the contribution of the "mirrorfull_mat"
secundary sources in my scene...:

IN:(Pathnames are cut for clarity)
augsburg@lenipc24:~$ rtcontrib -m mirrorfull_mat -o mirror.dat field.oct <
cavcylmeshgrid.dat
OUT:
rtrace: warning - too many modifiers in trace list

OK, so let's try with less modifiers...

3) Is rtcontrib able to compute the contribution of the "solar" source in my
scene...:

IN:
augsburg@lenipc24:~$ rtcontrib -m solar -o solar.dat field.oct <
cavcylmeshgrid.dat
OUT:
Nothing! No error, no results (no outfile) & no processor activity.

I hope this comes from a stupid error of mine...

Regards,

Germain

Hi Germain,

The "too many modifiers" probably means that the mirrorfull_mat is being reused many times in your file. You should define the material once somewhere and reuse it in our your included scene files.

As for the nothing output, this is of course suspicious, but without seeing your input files, quite impossible to diagnose. Perhaps you could send those my way in an off-list e-mail and I'll take a look.

Best,
-Greg

Just to let everyone else know, this issue was resolved off-list. Germain was inadvertently accessing version 3.5 of rtcontrib, which had a bug under Linux that was fixed long ago.
