What does someone need to get started using Radiance? Computer, Cad
versions, etc. Is there any beginners resource for this program?

Hi,

Something that has worked for me until now (I am still learning) is to
follow the tutorials (http://www.radiance-online.org/learning/tutorials)
from the basics, and to read the mailing list e-mails every now and then.

Until now I have not used any other CAD interface than SketchUp, so I am
useless in that area.

Hi Tim,

Germán has pointed you to a great page, and of course the mailing list archives are very useful. Randolph Fritz can get you a copy of the Rendering with Radiance text, which is the rosetta stone for figuring out a lot of Radiance's underpinnings. As far as CAD you can use just about anything, but there are some tools for specific CAD programs that make life easier going from CAD, to RAD. Thomas Bleicher has the su2rad program which allows you to take a SketchUp model and convert it to a Radiance project, complete with a GUI for assigning materials and the like. The DIVA for Rhino project facilitates the use of Rhinoceros models in Radiance. OpenStudio also leverages SketchUp for geometry creation, but allows you to convert the thing to Radiance as well.

Speaing about Rendering With Radiance,

How can I get "The Book" from Randolph Fritz? is a matter of sending him an
e-mail? how can I contact him? There is one copy on Amazon, but since it is
a reseller, I can not get it brought to Chile.

I am really interested on it.

THANKS

Yes, I have *Rendering With Radiance* available for US$35 + shipping and handling. There will--eventually--be a web site and a free PDF.

Meantime, anyone who wants copies can write me at randolph+pub@panix.com. US shipping and handling is US$6; Canada US$19, other international is usually US$30, but international shipping costs vary--write me with a shipping address for the price.

Germán, I'll be writing you directly with ordering information.

Dear expert,
I want to learn Radiance from the very basics. I have no experience using
command prompt in OSX or Linux. I am using Mac OSX El capitan, I already
installed Radiance on my Macbook. I have no idea how to start. I try to
follow the tutorial provided, but I dont know how to start.
Can someone pointing me the "very" basics step tuturial how to start using
radiance until the very simple simulation.
Thank you so much for your help

Hi Abdul,

Google suggests this page for getting started:

  http://blog.teamtreehouse.com/introduction-to-the-mac-os-x-command-line

You can also read all about the default shell (Bash) here:

  http://www.gnu.org/software/bash/manual/bashref.html

Assuming you've installed Radiance correctly, you should be able to access the commands you'll need, which are organized and described here:

  http://radsite.lbl.gov/radiance/whatis_comp.html

For creating Radiance scene descriptions, the Radiance reference manual is essential reading:

  http://radsite.lbl.gov/radiance/refer/ray.html

Finally, the Chapter 1 tutorial from "Rendering with Radiance" is still a reasonable place to start once you get everything working. The chapter also includes a nice introduction to the software, which is embarrassingly current for having been written in 1998:

  http://radsite.lbl.gov/radiance/book/ch1/ch1.pdf

As a short-cut, the tutorial files are also available from:

  http://radsite.lbl.gov/radiance/book/ch1/scene0.tar.Z

Best of luck!
-Greg

Hi Abdul,

Did you see the two tutorials on this page specifically for new Mac users?
Giulio and I prepared them 10 years ago when we were training alot of
people internally at Arup: http://radiance-online.org/learning/tutorials

I know they're dated and sparse, but they still have some useful things.

Since you're starting fresh, maybe you could keep a log of important things
you've learned and then later write them into a tutorial? No one is paid to
write tutorials for Radiance (okay, i was briefly paid for the genBSDF
tutorial but ended up spending more time than I was paid for), and the
community relies on each other to create tutorials. New user tutorials are
particularly difficult to write when you have 15 years under your belt
because you can't remember what you didn't know. Maybe you could turn your
struggle into gold for a new user?

Best,
Andy

Hi Abdul

You can also find an old (written 19 years ago...) Radiance tutorial from me on: http://radsite.lbl.gov/radiance/refer/index.html#cat4
I can nevertheless ensure you that the basic radiance commands that are presented in this tutorial are remaining exactly the same in today's Radiance version. Since that time there are only a few commands that have changed their names, namely:
rview became rvu
gcalc became icalc

I also add the same remarks as Andy...

Hope this will of help.

Also, good introductions to the bash and csh shells, as well as Unix
itself, are probably in order. But this is a lot of study. Still, the
following introduction, from NYU's high-performance computing center, might
perhaps be useful:

Thank you so much for the links for basic tutorials.
I am learning to figure out how to start simulation for simple room.
Btw, I install radiance on my macbook (OSX 10.11.4) using installer (dmg)
provided on the sites. How to check that the Radiance installel correctly?
If not successfully install, what is your sugestion for the best way to
install.

in a tutorial:
"Next you need to add "/usr/local/radiance/bin” to your system path, and you need to create a new system variable called “RAYPATH” and set it to "/usr/local/radiance/lib”. You can/should also add "/usr/local/radiance/man” to your MANPATH system variable.”
please give a step-by-step guide to add this system variable on mac.
then, how to check whether properly installed or not.

I am not familiar with the internals of the NREL installer. Perhaps it
already has done the job for you. Open a terminal and type

which rpict

If it comes back with a path like /usr/local/bin or /usr/local/radiance/bin
you are already set to use Radiance. The RAYPATH variable is not strictly
necessary but some scene setups expect it to be available.

A general discussion about setting environment variables in Mac OS (or the
previous versions) is here:

It's a few years old by now but I think most of this still applies. If you
are new to the Unix shell environment you can use this introduction to
setting variables:

http://osxdaily.com/2015/07/28/set-enviornment-variables-mac-os-x/

Please note that you can damage your user profile with these changes, which
could make it impossible to the terminal to clean up the mess. If you are
new to this you should ask around if someone has experience with Mac OS or
Linux and ask them to assist you. You can set up a second user and try your
modifications in that profile first. If it get's damaged you can just
delete it. In any case, make a backup!

Thomas

The NREL (Mac) installer does not set them for you, sorry. Andy McNeil used to have a YouTube video that showed exactly how to set these env vars, specifically for Radiance, but I can't find it. There are definitely links in the radiance-general archives.

I would definitely recommend setting the RAYPATH env var. Some of the Radiance internals rely upon it too, I believe — it's not just certain scenes.

Here is what I put in my .bash_profile for Radiance to work; if you install Radiance with the NREL installer and don't change the default install location, these are the paths you want. :

## Radiance path crap
export PATH=$PATH:.:/usr/local/radiance/bin
export RAYPATH=.:/usr/local/radiance/lib
export MANPATH=$MANPATH:/usr/local/radiance/man
export MDIR=/usr/local/radiance/lib/

I forget what "MDIR" is for. You may not need that one. The MANPATH line adds the Radiance "man pages" (i.e., documentation) to your system's man page search path. That way you can simply type "man rcontrib" at the command to pull up the man page for rcontrib, for example.

Note that this .bash_profile is hidden, because the filename begins with a dot ("."). File lives in your home directory ("~"), aka /Users/[your_user_name]/.bash_profile. Very easy to create/edit this file from the command line using vi, or pico.

Good luck!

I am not familiar with the internals of the NREL installer. Perhaps it already has done the job for you. Open a terminal and type

which rpict

If it comes back with a path like /usr/local/bin or /usr/local/radiance/bin you are already set to use Radiance. The RAYPATH variable is not strictly necessary but some scene setups expect it to be available.

A general discussion about setting environment variables in Mac OS (or the previous versions) is here:

It's a few years old by now but I think most of this still applies. If you are new to the Unix shell environment you can use this introduction to setting variables:

http://osxdaily.com/2015/07/28/set-enviornment-variables-mac-os-x/

Please note that you can damage your user profile with these changes, which could make it impossible to the terminal to clean up the mess. If you are new to this you should ask around if someone has experience with Mac OS or Linux and ask them to assist you. You can set up a second user and try your modifications in that profile first. If it get's damaged you can just delete it. In any case, make a backup!

I installed Radiance on OSX 10.11.6 using this:
https://github.com/NREL/Radiance/releases/download/5.0/radiance-5.0.0-Darwin.dmg

in a tutorial:

"Next you need to add "/usr/local/radiance/bin” to your system path, and you need to create a new system variable called “RAYPATH” and set it to "/usr/local/radiance/lib”. You can/should also add "/usr/local/radiance/man” to your MANPATH system variable.”

please give a step-by-step guide to add this system variable on mac.

then, how to check whether properly installed or not.

Thanks,

Abdul

Also, good introductions to the bash and csh shells, as well as Unix itself, are probably in order. But this is a lot of study. Still, the following introduction, from NYU's high-performance computing center, might perhaps be useful:

Hi Abdul

You can also find an old (written 19 years ago...) Radiance tutorial from me on: http://radsite.lbl.gov/radiance/refer/index.html#cat4
I can nevertheless ensure you that the basic radiance commands that are presented in this tutorial are remaining exactly the same in today's Radiance version. Since that time there are only a few commands that have changed their names, namely:
rview became rvu
gcalc became icalc

I also add the same remarks as Andy...

Hope this will of help.
