rcontrib for rendering - missing required modifier argument

Hello Greg,
This is the command line:

Hello,

I have problems with rcontrib program with Windows 8 SO. I am trying to do
Example 1 of A McNeil The Three-Phase Method. I would like to render with
vwrays with a windowglow in a test room. However, missing required modifier
argument message script. Does anyone know what is the problem with the
modifier?

Thank you in advance,
Kind regards,
Urtza.

Hi Urtza,

The problem is the use of double-quotes for "vwrays -vtv -vh 94 -vv 70 -vp 1.5 5 1.75 -vd 0 -1 0 -x 600 -y 600 -d", which used singe back-quotes under Unix. This replaces the command with its output on the command line, something Windows does not do. Substituting with double-quotes is the wrong thing to do. Instead, execute this command yourself, then cut and paste the output into the rcontrib command line in its place.

The output is "-x 600 -y 392 -ld-", so you would use:

vwrays -ff -vf -vtv -vh 94 -vv 70 -vp 1.5 5 1.75 -vd 0-1 0 -x 600 -y 600 | rcontrib -x 600 -y 392 -ld- -ffc -fo -o vmx/window_%03d.hdr -f klems_ang.cal -b kbinS -bn Nkbins -m windowglow -ab 2 12 -ad 50000 -lw 2e-5 model_vmx.oct

As the actual command in Windows.

Hi Greg,

I tried following your indications and it worked, although, I had to remove
Nkbins because it is undefined variable. I do not way but it could be not
having such as the Tregenza skydiscretization...
I removed and thus, the default number is 0:

  C:\Radiance\test>vwrays -ff -vtv -vh 94 -vv 70 -vp 1.5 5 1.75 -vd 0 -1 0
-x 600
  -y 600 | rcontrib -x 600 -y 392 -ld- -ffc -fo -o vmx/window_%03d.hdr -f
klems_an
  g.cal -b kbinS -bn Nkbins -m windowglow -ab 12 -ad 50000 -lw 2e-5
model_vmx.oct
  rcontrib: Nkbins`RC: undefined variable

   C:\Radiance\test\20150505>vwrays -ff -vtv -vh 94 -vv 70 -vp 1.5 5 1.75
-vd 0 -1
   0 -x 600 -y 600 | rcontrib -x 600 -y 392 -ld -ffc -fo -o
vmx/window_%03d.hdr -m
   windowglow -ab 12 -ad 50000 -lw 2e-5 model_vmx.oct

However, generated window_000.hdr file does not have light. It is a black
image, even though, the render generated by rvu of the room it is ok.
Do you know why does it happen?

Thank you!
Kind regards,
Urtza

What do you use to view the HDR image? Try typing:
ximage -e auto window_000.hdr

This will automatically adjust the exposure of your image upon initially opening the file. It could be that your image does have non-zero values but the exposure is skewed in your viewpoint making it look black with the default exposure value.

Or type
ximage window_000.hdr
then hit the ‘a’ key while ximage is active to view it with automatic exposure
while ximage is active you can also hit the ‘=’ key and click a point in the image to adjust the exposure according to various points in the image

However, generated window_000.hdr file does not have light. It is a black image, even though, the render generated by rvu of the room it is ok.

Hello Christopher,

Thank you for your response.
I think that in the radiance-4.2.2-win32.exe there is not the ximage
program. I usually use RadianceIV.exe program from Ecotect.

C:\Radiance\test\20150505\vmx>ximage window_000.hdr
"ximage" no se reconoce como un comando interno o externo,
programa o archivo por lotes ejecutable.

However, I find klems_full.cal file that it has all information about
kbinS and Nkbins.
Now I have 145 .hdr files. They have light source, but the room walls are
black (is it usual?)

In reference to /pcompos,/ window1_*.hdr is invalid argument. Do you know
why?
  C:\Radiance\test\20150505\vmx\images>pcompos -a 10 -b 1 1 1

Hi Urtza,

  You should not be using the file "klems_ang.cal" but something like
"klems_full.cal" or klems_int.cal. This is why Nkbins was undefined,
and probably at least one reason your simulation is not working.

Welp, it appears that the '*' wildcard expansion does not work with Windows in the standard shell, even though the wildcard does work with other internal commands, such as 'type' (Windows-speak for 'cat'). As they say: WTF?

- Rob

P.S. The wildcard does expand correctly with pcompos in a Cygwin shell, so there's that.

P.P.S. You can install a lightweight Cygwin shell by simply installing Git for Windows (https://msysgit.github.io/). You get a proper BASH shell in Windows with minimal effort. Highly recommended.

The "cmd" shell does not do filename expansion; commands that support it
do it themselves--"cmd" is quite minimal. To make that pcompos command
work, it would have to be provided with the full list of files, spelled
out. This could be done in Windows PowerShell or perhaps via some
combination of command. Anyone who knows Windows scripting well willing
to provide an alternative?

Rob,
Getting off-topic, but not sure if it warrants a separate thread... you imply that we can run Radiance commands in the Git for Windows bash shell. Is there an advantage to doing so, in comparison to Cygwin (which I have used in the past)? Both would have the clear advantages of being able to use more powerful scripted commands when compared to the Windows cmd prompt, but Git-bash is more lightweight while Cygwin would be more powerful (for things unrelated to Radiance?)? In both cases install according to normal Windows Radiance installation and adjust paths as necessary in each environment?
