Updated Radiance Installers Available

Hi all,

Just a quick note, NREL recently updated all the installation packages for
Radiance, and these are available on the OpenStudio website. A user
pointed out to us that the essential files in ray/src/cal/cal were not
making it into the installation directory -- apologies all around. Greg
Ward also made a recent change to one of the MGF converters, so that code
change is reflected in all of the packages as well. You can find all of
NREL's Radiance package offerings at:

Trace on, people.

Hi Folks,

We have posted updated Radiance binaries for Windows, Mac and Linux on the
NREL OpenStudio website.

Happy rendering!

Hey Rob,

What a coincidence as I was just downloading and installing openstudio today... So I assume the radiance binaries are as of today rather than May 16?

Hi Jack,

Good timing. Yeah, the updated packages were pushed up to the site last
night, so you have the new ones. I updated the datestamp on the page
this morning. The packages were actually made July 2, just took a while
to get 'em posted. =)

Let me know how you like OpenStudio!

Howdy folks,

Just wanted to let the community know there are updated Radiance
installers posted on the NREL OpenStudio website, on the Radiance
support page (sorry for the wrapped/busted links, you gotta copy/paste):

https://openstudio.nrel.gov/getting-started-developer/getting-started-
radiance

A couple of recent additions are support for the planispheric view type
in the Qtrvu application (thanks to Zack Rogers for pointing out the
deficiency), and the addition of a rewrite of the objview.csh script in
Ruby, so now Windows users have access to that utility. The Ruby version
of objview also has a luminaire viewer option (-l) which takes an
ies2rad-generated luminaire description and places it in a box so that
the luminous distribution can be evaluated visually. See the man page
for details.

Note also there is a new Sheriff in town, vis a vis contribution
counting. Greg has added a new version of rtcontrib, called ³rcontrib².
It¹s way faster than rtcontrib, and should be used as a direct
replacement for rtcontrib in your daylight coefficient investigations.
The makeall script actually doesn¹t even compile rtcontrib anymore,
instead creating a symlink called rtcontrib that points to the new
rcontrib. We have decided to compile both programs in the NREL
installers, in case anyone wants to do some comparisons or validations
between the two. Point being if you use the NREL Radiance installers,
When you call rtcontrib, you are in fact getting rtcontrib! So, there.

BTW, we have also posted documentation on how to use the
Radiance-related functionality in OpenStudio, which is currently
implemented in a series of Ruby scripts. You can check that out here:

https://openstudio.nrel.gov/getting-started-developer/getting-started-
radia nce/openstudio%E2%80%99s-radiance-functionality-documentation

Have fun, kids.

Good to know!

Is gendaymtx available in the HEAD version of Radiance? Is the GPU version
of dctimestep needed for using that?

THANKS VERY MUCH

Hi folks,

Just a quick note to let you all know that the Radiance installers have
been updated, and are available for download at the NREL OpenStudio site.
These packages include the brand new 'gendaymtx' utility that greatly
speeds up the annual calculation when using the daylight coefficient tools
in Radiance.

We hope to add gendaymtx into the OpenStudio tool chain and workflow in
the coming weeks, but in the meantime, I'm sure Greg would appreciate any
feedback from users willing to try it out on their own, especially those
Windows users out there. There's a man page explaining its use, and it's
pretty straightforward.

Grab yours here:

Ok, bye.

Yes, gendaymtx is in the HEAD version, and dctimestep has been updated as well to handle its output. It does not use GPU (or even CPU) acceleration, but it's still very fast compared to running one step at a time. (My test runs took a couple of minutes for a typical 8760-step weather tape.) It will even produce a series of images, though that takes longer due to the i/o requirements.

Best,
-Greg

German,

dctimestep has been updated to allow to use the sky matrix file from
gendaymtx. Look at the -n option in the dctimestep manpage. This update
to dctimestep replaces the need for the gpu version of dctimestep
(dctimestepgpu / dctimestepcpu) that some users may have received directly
from me.

Hi, lighting geeks.

This is just a note to let you all know that we've updated the Radiance binaries, based on the latest LBNL-hosted Radiance code repository.

https://openstudio.nrel.gov/getting-started-developer/getting-started-radiance

Happy simulationification.

All,

Just a quick note, there are updated installers for DOE/LBNL's Radiance available for all major platforms available on NREL's website, here:

https://openstudio.nrel.gov/getting-started-developer/getting-started-radiance

These are based on the latest (HEAD) state of the Radiance source tree, as of June, uh, I dunno, sometime last week. =)

Greetings, ray wranglers.

We are pleased to announce the availability of fresh Radiance installers for Windows, OSX, and Linux, on the NREL Radiance Git mirror (https://github.com/NREL/Radiance<https://github.com/NREL/Radiance/releases/tag/4.2.a.4>). This new batch of installers is based on our tag 4.2.a.4 (https://github.com/NREL/Radiance/releases/tag/4.2.a.4 ) which was created today, and includes all updates to HEAD as of this morning. These tags are *unofficial* snapshots of the *official* LBNL Radiance source tree (HEAD), located at: http://radiance-online.org/cgi-bin/viewcvs.cgi/ray/?pathrev=MAIN.

A couple of things worth noting for this release:
* The Windows installer now optionally adds the Radiance "bin" directory to the user or system %PATH%, and creates a %RAYPATH% environment variable and sets it to the Radiance "lib" directory.
* A couple of nifty new utilities written by Axel Jacobs are included, ltview.pl and ltpict.pl. They work similarly to objview and objpict, but are intended for visualizing luminaires (there's a manpage for each =)). ltview.pl supersedes the "-l" option to objview.rb that was added last year, and therefore objview.rb has been removed from the Radiance source.
* As always, see the release notes for more info: https://github.com/NREL/Radiance/blob/4.2.a.4/doc/notes/ReleaseNotes

Follow the photons, people.

Greetings, light lovers!

A fresh batch of packages (installers) has been posted to the NREL Radiance GitHub site:

A couple of noteworthy doodads:
* These packages are based on Radiance 4.2.b, which now includes a new Hessian-based error control protocol for the ambient calculation
* The stdout from gendaymtx has a new format, which breaks the OpenStudio daylighting routines. We are working on a fix.

In addition, the Radiance 4.2.a.4 Windows package was updated, and now includes the GUI applications, such as rvu.exe. This idiot regrets the omissions.

Now go throw some virtual photons around.
