Hi Zack,
Many thanks for your advices.
Regarding SPOT Pro, it seems that it can work out annual simulation for CFS with BSDF but for grid points we still need to use command-line (as you clarified). Also, we still need to use command-line (radiance) to generate BSDF that will be used with SPOT Pro . Is that right?
Also, what is the difference between SPOT Pro and Daysim tools in terms of accuracy and flexibility (as both using Radiance engine)?
Regards
Ikrima

Hi Ikrima,
One Windows-based user interface that might fit your needs is the Sensor Placement + Optimization Tool (SPOT) <http://www.daylightinginnovations.com/spot-home>
daylighting software. A new version, SPOT Pro, was just released and is now available for download at the above website.
SPOT Pro provides an interface to Radiance and has the capability to perform annual daylighting simulation using BSDF files to describe Complex Fenestration Systems (CFS) and allowing you to schedule automated and/or manual control of the window treatments. The SPOT interface allows you to build simpler orthogonal geometry, assign materials and render or simulate throughout the year. Importing from sketchup can be done behind the scenes and will be available soon. SPOT also allows for further analysis and optimization and photosensor systems in your daylit space if desired.
Calculation of vertical illuminance grids, or other directional illuminance points, if needed, are not built into the program but can certainly be calculated behind the scenes of a SPOT model without too much command line interface.
The software is in a final Beta testing stage where we are testing downloads, installation and operation on different machine types, operating systems, and MS Office versions. If the trial version downloads, installs, and starts up on your machine - chances are you are good to go. If not, please report issues to [email protected].
Good timing for your questions - SPOT Pro was just posted and I was just about to send out such an announcement to the list.
Regards,
Zack

Hi all,
I just started using Radiance and it seems to me difficult so I need
your advices please.1. As Radiance Desktop is no more recommended for CFS daylighting,
what is the alternative if one wants to study illuminance distribution
(points values) inside an office that has CFS (with both diffuse and
specular materials)?2. Is there any user-friendly-interface program that can do the
task without the need to work with command-line procedure (that I am
not good with at all)?3. If it?s compulsory to use command-line tools, how can we
construct/import CAD geometry and assign its materials?4. And, is there a step-by-step tutorials on how to run Radiance
(in case of command-line)?Your help/advice is really so appreciated.
Many thanks in Advance J

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

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

Hi Greg,
Thank you very much!
I will try to follow your indications.
Best wishes,
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.
Cheers,

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.

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
