Not sure where to get the password to use radiance after installation...any
advice?

I've already taken the download from the website and it mentioned to enter the
password received after registration, just not sure where to find it.

Hi, my is Germán Osma, I'm student master in green buildings. Few days ago, I
downloaded DESKTOP-RADIANCE. But I need to know some things to begin to use it.
1. In the manual says that I should install AUTOCAD 2000 or R14, but I have
AUTOCAD 2008, and not you how to make it work.
2. Are the manuals for RADIANCE-LINUX useful for DESKTOP-RADIANCE?
3. How do I work DESKTOP-RADIANCE without ECOTECT and AUTOCAD? Should I work in

thanks for your attention!!!

hi, I am a college student doing a urban design project for my professor. The
purpose of the project is to evaluate human behavior based on the light level in
a room.

I understand radiance can simulation time, date, etc. But when I used image
analysis, it only gives me a number output of a workplane(ex: a desk). Is there
anyway I can have a average number of illuminance in a room? then the user could
decide if to turn the light on or off based on his/her preference. Also, is
there a way to set the light on/off when I proceed the simulation.

Thank you.

I am very new with radiance.. I am trying to work in linux. I wanna
use gensurf command.for that I need to know which type of file should
be used as input. an image file or something else.. I have tried some
mesh data but its showing bad number of data points..

Please help me out.

Hi Vangelis!

Thank you very much for your attention.

I've tried to do so by importing (in Grid Management) RADIANCE results
to ECOTECT (version 5.60) in .DAT format (035.dat,087.dat), but values
are totally wrong than in RADIANCE.

I will have a try your method.

Thanks!

Iskandar.

Hello!

How can I measure the working plane illuminance by using the Radiance?
Because I have tried so many times, and looked everywhere on the
Internet, but still cannot find out the method to estimate the
required result, but here's only the illuminance level of the wall,
ceiling and wall. could anyone tell me about the process of evaluating
the illuminance level of working plane (0.8m above floor)?
Now I am using ECOTECT for the simulation experiments.

Thank you very much in advance!

Wir wünschen ein fröhliches Weihnachtsfest

und einen Superrutsch in ein gesundes und erfolgreiches 2009!

hi,
Can DR simulate a self-luminous wall or window? Can I create a new
luminaire, and define the self-luminous object as a luminaire?
I try to define a new luminaire in DR, but after I follow all the steps
in DR, I get the error which says "Couldn't open imposter geometry file
for parsing!". Can someone tell me a more clear figure to do this? or
tell me another way to create a new luminaire. Thanks a lot.

There is some discussion of this in the Rendering with Radiance book.
If you are only concerned with the color appearance of the final
rendering, you can simply adjust the RGB values of the sources being
used.

If you want to effect calculations of illuminance values (lx,fc), then
you're going to have to wait until my thesis is done. I am currently
developing a script to account for the SPDs of sources and the
reflectance distributions of surfaces in radiance calculations.

Dear Chas

I want to install Radiance 1.02 and downloaded it, but I can't do it
because it needs a password for uncompressing th Zip file. I really
appreciate you if you can tell me how to do that.

I am looking forward to hearing from you.
Best regards,
Majid Miri

Hello George,
TY for coming back to us.
The software that I am using is the Radiance Module of the IES
(APACHE) suite. This is mostly used for thermal prediction,
overheating, also compliance with local building regulation,
ventilation studies etc. The mein reason I mentioned the fact that it
was not RADIANCE or DESKTOP RADIANCE is because the data inputting
maybe (and probably is) completely different (unfortunately I have
never used RADIANCE - I am not allowed to have an old AutoCAD version
which had the add-on RADIANCE module, so don't know for sure). I do
not have a library of materials from which to choose, for example,
the "MIRROR"; instead, I assign materials/surface properties to the
wall, windows etc. Likewise, I am sure that you have your libraries,
but you can also modify them and add different/new materials, or
change the value slightly; glass manufacturers, for example, are
continuosly producing new coatings with different properties etc.

TY very much for the link, it seems to confirm that I am not 100
miles away; infact I can see, for example, that the "metal material
types" use 1.0 for full specularity and 0.5 for a "dirty" mirror.
Ideally I would need a " wavy" funtion to my specularity, but I do
not have a "METAL2" definition. No biggies, this is probably outside
the scope of my work, which is only to check DF in classrooms to see
if they comply with the reccomended guidelines.

With regards to mkillum, I think that I have seen "functions"
somewhere, but I have never used any before and I cannot check right
now (License availlability issues).

TY again,
Regards,

Willy

Hello Willy,

I can't see why your approach shouldn't work apart from:- your not
specifying what software you are using, and the interreflections
being a problem when using many verily highly specular surfaces.

So far as materials go, for mirror in Radiance I would use MIRROR
material! Hasn't the software you use got this material? For specular-
reflector-lightpipe/in-lightwell I would use the mkillum program as
the skylight source at the top as well. Doesn't the software have
that function?

Were you aware of the guidance on Radiance material types for
Rayfront (at http://www.schorsch.com/rayfront/manual/matdef.html ),
which uses Radiance materials formats and engines? Tis most helpful,
I think. As it says, a value >0.1 for specularity is 'unusual'. Hmmm.

Good luck.

Regards,
George

Hi all,

to start with, I am using the Radiance tool as implemented in a
different software suite, but I imagine that this is fairly
irrelevant.

I am looking at daylight factors in classrooms using CIE uniform sky,
and at the use of light wells to "brighten up" the back of deep
classrooms. I want the maximum amount of light possible been
channeled down the light well, so I thought that some aluminium foil
coating could be used. For this coating I used the following values:
R-Refl = 0.91, B-Refl = 0.92, G-Refl = 0.92 (this is roughly the
reflectance of polished aluminium at the different wavelength for
Red, Green, Blue). For specularity.... I took the average of the 3
values, so I used 0.917 (this is a pure guess, but I thought that  a
value of between 0.9 and 1.0 would have been appropriate - ok maybe
1.0 would have been too optimistic, so any 0.9, 0.925, 0.95 would
have been good). I assumed the surface to be polished, hence
roughness = 0.

Is this approach valid.. or did I completely miss the point?
Where can I find some guidance? For example, how would I go to
simulate a mirror?

many thanks,

willy

Hi Everyone,
I tried one of the tutorials in Ecotect 5.2 and I discovered that my
Desktop Radiance download does not have the brick1.cal function
file.Pls can anyone help me out? I have tried the cygwin package, but
to no avail.
Thanks everyone and more grease to your elbows for keeping this
usergroup functioning.

Hey All!  Can anyone give me a detailed difference between Desktop
Radiance and Radiance??  It would be much appreciated!

Hi Tracy,

remembering:

TARGET point refers to where you are looking.
CAMERA point refers to from where you are looking.

so, imagine that you are holding a photo camera, target point means the
center point of what you want to photograph, and camera point means
where you are (x and Y coords) and how fa from the ground you are (z
coord).

after that, you MUST save it like a view.

and in DR menu SIMULATION > Camera> you have to choose it.

I dont have DR on my computer, so I'm tryng to remember these steps, so
I hope that my memory is still working.

Hey everyone!  I've been having problems setting up the camera in
desktop radiance.  I can get a very good image of the outside of the
room I build but cannot get any views of the inside.  When I set up a
camera and switch to that view, it just shows the inside of the camera
and nothing else.  Can anyone help me?!?!

Hi all,

I have a problem when I simulate my grid points. It creates the files
and entities alright but an error comes up when the Database is
Synchronising. The error says in a simman dialog box:

         " Error: CopyItem: Item doesnt have a fikle, exiting"

i press ok, then the next error message says:

         " Error copying graphic editor item 2548085"

Please help! it would be much appreciated.

Thanks,

Adriana

Thanks Evangelos!

Adriana,

Run from your BIN folder a register to RADIANCE, clicking twice on
file ray_reg.reg included during the instalation

I think that will be enough to avoid this error.
