[Radiance-general] Official 5.0 release

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, Max and Linux 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,

++++++++++++++++++++

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).
