Rob Guglielmetti of NREL, Dan Fuller of LBNL, and yours truly have put together a new official release of Radiance, version 5.2, available from the usual download point. The NREL installers may be found here.
Some of the major changes and bug fixes since the last official release are mentioned in my talk from last month’s workshop in Loughborough, here. The new additions to gendaylit and evalglare by Jan Wienold and Aicha Diakite are described in their talk.
Some brief highlights are listed below:
psketch program for stylized objects
new rmtxop operators
rvu “origin” command
rtpict tool for parallel rendering
aBSDF primitive for peak extraction
Please post here or to radiance-dev if you run into any problems with the installers or the release.
P.S. An issue was discovered with the gendaylit man page. The ray/doc/man/man1/gendaylit.1 document did not get updated with the utility. The updated PDF version is available with the other man pages in the usual place. A direct link is here. The updated nroff source file is in the CVS repository here.
