rcontrib for rendering - missing required modifier argument

radiance-general
4

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.

Best,

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 "window1_*.hdr" > al
lwindow1.hdr
window1_*.hdr: Invalid argument

Thank you in advance,
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.
Do you know why does it happen?

Thank you!
Kind regards,
Urtza
