5.0.a.7

Change open filetype mask in rvu Windows app

5.0.a.6

This is a minor update from the recently-released Official 5.0 Release. Included in this tag are some photon map updates and cleanup, as well as the inclusion of the meta files necessary for x11meta to work.

Notes:

• Folks wishing to use x11meta will also need to add the MDIR system variable to their environment. If using the NREL Mac installer posted here, add the line export MDIR=/usr/local/radiance/lib/ to your ~/.bash_profile (note the trailing forward slash).
• x11meta is not included in the Windows installers, because it's an x11 program.

Announcing official Radiance 5.0 release

It's been over a year since the last official release, and 5 years since the last major one. The biggest change is the addition of Roland Schregle's photon-mapping code, whose integration was sponsored and coordinated by the Lucerne University of Applied Sciences and Arts, Competence Centre Envelopes and Solar Energy (www.hslu.ch/ccease) in collaboration with the US Dept. of Energy. Special thanks to Roland himself, Stephen Wittkopf, Lars Grobe, David Geisler-Moroder, and to Amir Roth, who covered my part in the final push.

Another significant addition/incorporation in 5.0 is Jan Wienold's evalglare tool, which he provided right before this year's workshop. I would also like to thank Eleanor Lee (as always) for her ongoing support and management of Radiance development at LBNL.

The new release will be available from the following link, together with Mac OS X binaries (which hopefully work under Yosemite as well):

NREL will post Radiance 5.0 binaries for Windows (32- and 64-bit), Mac (64-bit) and Linux (64-bit) on the NREL Radiance GitGub mirror, here:

A number of important fixes and features come in addition to the photon map. Below are a few highlights.

Cheers,
-Greg (Ward)

---

• Created wrapBSDF tool and incorporated into genBSDF along with new rfluxmtx computation.
• Added left-hand coordinate sytems to rfluxmtx to correct problems with coordinate axis orientations pointed out by David Geisler-Moroder.
• Added color output to genBSDF (+C option) and support for color rendering of Klems and tensor tree data.
• Fixed bug discovered by Jacob Jonsson in Klems BSDF interpolator that caused it to over-predict normal transmittance and reflectance.
• Added ability to read input from commands in dctimestep and rmtxop.
• Added photon map support to rad. Fixed some double-counting issues in photon-mapping spotted by David Geisler-Moroder.
• Added photon map support to trad.
• Prompted by Roland S., added option to have pcompos -a order rows from top rather than bottom of image.
• Changed dctimestep to accept matrix as well as BTDF input in the VTDs invocation mode. This permits the output of rmtxop to be used in a pinch when combining multiple BTDF layers, although interreflection between layers is not accounted for properly as it is in the WINDOW program.
• Added Jan Wienold et al.'s evalglare to distribution.
• Hopeful fix to deadlock issue under Mac OS X 10.10.x (Yosemite).

5.0.a.5

Fixed bug in sample testing discovered by Rob G.

5.0.a.4

This is the fourth edition of NREL Radiance binaries built from the 5.0a codebase. In support of OpenStudio, we are once again providing 32-bit Windows builds for this release.

Highlights:

• Jan Wienold's evalglare is now included in the Radiance source
• dctimestep accepts matrix BSDF data for the T matrix
• miscellaneous bug fixes and improvements

NOTE
This Mac release includes a hopeful fix for the Mac OSX 10.10 multithreading issue. You can help test, even if you cannot build your own binaries! Just download the Mac installer below and reference this post from the radiance-general list for details.

5.0.a.3

This is the third set of alpha release packages for Radiance 5.0a.

The highlights reel:

• bugfix for double counting in the photon map code
• qt-rvu updated to use Qt5 (thanks to @axelstudios)
• 64-bit long support for Windows
• 64-bit binaries for Windows.(!)

We are now offering packages in 64-bit only, across all OpenStudio-supported platforms. Welcome to 2009.

5.0.a.2

Radiance v5.0a now does Windows. =)

5.0.a.1

This is the first v5.0 release of Radiance, including Roland Schregle's photon map work, fully integrated. Windows installers to follow RealSoonNow[TM].

From the Release Notes:

Version 5.0

Improved ambient extrapolation to avoid zero values. Actual
threshold set to 5% of recorded value.

Changed anisotropic Gaussian and Ashikhmin models so that
illegal orientation vectors are dealt with more gracefully.

Created wrapBSDF tool and incorporated into genBSDF along
with new rfluxmtx computation.

Initial check-in of Roland Schregle's photon map integration.
New 5.0a version designation as suggested by Andy McNeil.

Added left-hand coordinate sytems to rfluxmtx to correct
problems with coordinate axis orientations pointed out by
David Geisler-Moroder.

Added color output to genBSDF (+C option) and support for
color rendering of Klems data.

4.3.a.2

Added needed include file for rand() and RAND_MAX under Windows

4.2.2

This is Radiance Release 4.2, patch level 2. Change(s) since last patch release listed below; change(s) that caused a new official patch release in bold.

• Fixed bug in rsensor related to having many rows (altitude) and few columns (azimuth) in sensitivity file.
• Fixed floating point round-off error in new Hessian calculation for some systems (Windows, primarily).
• Fixed bug in tensor tree BSDF code that caused bus error on some systems, and may have been source of other errors as well.
