I am using the 5.1.0.
According to my code that I mentioned before, the "combine.hdr" was
rendered, but it could not be well opened and displayed like other patch
images with ".hdr".
Actually, I have been also trying the method of "rfluxmtx" , then it
returned " cannot load '-o'" when I run bash.
#vwrays -ff -x 600 -y 600 -vf views_up.vf | rfluxmtx @rtc.opt -v -ffc '
vwrays -d -x 600 -y 600 -vf views_up.vf ' -o sky_tre_p%d.hdr - test_sky.rad
-i a.oct
I will appreciate your helping.
Best,
Clarence

Hi Clarence,
This should be correct. What version of Radiance do you have? (I.e., what
does "rpict -version" return?)
Does it report any error at all? Is the output file completely empty?
It works when I run it using 5.1, and I'm pretty sure it will work for
anything later than the 4.1 release, which was in 2011.
Cheers,

Thanks for the advice.
I have tried, but the "result.hdr" was not a format of picture, which meant
that the rendering was failed.
#gensky 3 21 10 +s -a 22 -o 114 | genskyvec -m 1 -c 1 1 1 > tmp_skydist.dat
#vwrays -ff $vw |rcontrib @rtc1.opt -ffc $(vwrays -d $vw) -V+ -f
tregenza.cal -b tbin -bn Ntbins -o first_tre_p%d.hdr -m skyglow
test_sky_sun.oct
#dctimestep first_tre_p%d.hdr tmp_skydist.dat > combine.hdr
Or, any parameters should be needed in the third line?
Best,
Clarence

Hi Clarence,
Rather than trying to fix Axel's old script, it's better to use the simpler
and more efficient dctimestep method:
dctimestep first_tre_p%d.hdr skydist.dat > result.hdr
You can also simplify the rcontrib step using the rfluxmtx program, but what
you have is fine.

Dear all,
I've been trying to render the Tregenza sky patches by using rcontrib. Each
patch was rendered successfully, but when I use "pcomb" which contains
"tregsamp.bash" by Axel Jacobs to combine them, the "combined.hdr" was a
black picture.
#vwrays -ff $vw |rcontrib @rtc1.opt -ffc $(vwrays -d $vw) -V+ -f
tregenza.cal -b tbin -bn Ntbins -o first_tre_p%d.hdr -m skyglow
test_sky_sun.oct
#pcomb -h $(bash apply_tregsamp_1.bash) > combine_1.hdr
#the original bash script below by Axel Jacobs was changed in order to be
consistent with my code.
# Path to the patch images
imgpath="image_fisheye/patches_tre/first_tre"
for i in $imgpath_*.hdr; do
# Scan patch number from file name
patch=$(ls $i \
>rcalc -i "$imgpath_p\${pnum}.hdr" \
-e "\$1=pnum")
# Get multiplier from dat file, based on record number
multi=$(cat tmp_skydist.dat \
>rcalc -e
"diff=$patch-recno+1;absdiff=if(diff,diff,-1*diff);
\$1=if(absdiff,0,\$1);" |total)
echo " -s $multi $i"
done
#EOF
Thanks,
Clarence
