# Line 1140 | Line 1140 | of recursive routines using sets to avoid overrunning
1140   the stack limit.
1141  
1142   ==============================
1143 < Version 3.6
1143 > Version 3.6 (Released 10/21/04)
1144  
1145   Modified 4-byte RGBE encoding routine to avoid problems
1146   when one or two primary values is negative and the other(s)
# Line 1343 | Line 1343 | Fixed bug in rcalc where it sometimes wasn't parsing t
1343   correctly.
1344  
1345   =====================
1346 < Version 3.7
1346 > Version 3.7 (Released 7/25/05)
1347  
1348   Fixed bug in source occluder cache which caused consistency error
1349   for distant sources and mist materials.  (Thanks to Mark Stock for
# Line 1489 | Line 1489 | line on the input.  This was not intentional, but I de
1489   behavior so I documented it rather than changing it.
1490  
1491   =====================
1492 < Version 3.8
1492 > Version 3.8 (Released 10/17/06)
1493  
1494   Fixed Russian roulette ray termination, which was doing the opposite of
1495   what it should have been doing, resulting in overestimated values below
# Line 1609 | Line 1609 | not being accounted for properly.
1609   Added -h option to pcompos and pcomb to eliminate verbose headers.
1610  
1611   =====================
1612 < Version 3.9
1612 > Version 3.9 (Released 3/30/08)
1613  
1614   Added -spec option to falsecolor to restore original spectral color scale.
1615   Also added "-s auto" option to automatically set the maximum value.
# Line 1666 | Line 1666 | rays to average over, rather than only produce a singl
1666   record (which can now be done with -c 0).
1667  
1668   =====================
1669 < Version 4.0
1669 > Version 4.0 (Released 3/12/10)
1670  
1671   Added -n option to rvu to provide parallel rendering.
1672  
# Line 1705 | Line 1705 | BSDF-based annual calculations.  This is the first Per
1705   be added to Radiance.  Hopefully, others will follow.
1706  
1707   Added klems_int.cal file to compute Klems bins for windows.
1708 +
1709 + Created genskyvec  utility to sample a particular sky and
1710 + evaluate average radiance over the standard Tregenza sky patches.
1711 +
1712 + Created dctimestep program to compute a set of sensor values or
1713 + a combined image for a particular time using the daylight
1714 + coefficient method.
1715 +
1716 + Created src/rt/rayfifo.c for first-in/first-out handling of
1717 + multiprocessing by raypcalls.c.
1718 +
1719 + Added -n option to rtrace for executing on multiple cores
1720 + using new rayfifo calls.
1721 +
1722 + =====================
1723 + Version 4.1
1724 +
1725 + Changed ranimate behavior so remote login under a different user
1726 + doesn't necessarily require the presence of the originating user's
1727 + home directory.
1728 +
1729 + Changed standard transmission function normalization back to what
1730 + it was in version 3.5, following recommendation of David Geisler-Moroder,
1731 + who pointed out that the revised BTDF increased too much at grazing.
1732 +
1733 + Changed rad behavior with -N >1 on single view to call rpiece.
1734 +
1735 + Updated SCons build system for MINGW compilation, thanks to Christian
1736 + Kohler.
1737 +
1738 + Added -u option to rlam for unbuffered output.
1739 +
1740 + Modified dctimestep to accept sky vector and daylight coefficient matrix
1741 + or list of images to sum together, as suggested by Andy McNeil.
1742 +
1743 + Created genBSDF script to generate BSDF in Windows XML format.
1744 +
1745 + Modified mkillum to accept detailed geometry from BSDF XML files.
1746 +
1747 + Altered obj2rad to ignore zero normals (thanks to Jack de Valpine for
1748 + suggestions and help).
1749 +
1750 + Fixed bug in genklemsamp that caused non-uniform sampling over surfaces.
1751 +
1752 + Fixed bugs in rhoptimize and rhcopy for 64-bit compilation.
1753 +
1754 + Made a change to avoid problem using gcc --fast-math compile option.
1755 +
1756 + ****** COMPATIBILITY CHANGE ********
1757 + Changed behavior of rtrace and rtcontrib so that every scanline is
1758 + not flushed when both -x and -y are set.  This avoids flush delays
1759 + in rtcontrib for large numbers of output files and delays while
1760 + rendering images using rtrace with the -n option.
1761 +
1762 + Added ability for rsensor to output ray origins and directions
1763 + rather than actually loading octree and computing sensor value.
1764 +
1765 + Fixed old bug in obj2rad where it would stop processing and
1766 + report a syntax error if the "void" type is used in the map file.
1767 +
1768 + Updated reflection model according to EGSR 2010 paper by David
1769 + Geisler-Moroder and Arne Duer.
1770 +
1771 + Replaced C-shell version of falsecolor with Perl script written
1772 + by Axel Jacobs.
1773 +
1774 + ****** COMPATIBILITY CHANGE ********
1775 + Changed -sj (specular jitter) option to something called specular
1776 + sampling (-ss), which if set less than 1 has the same behavior as
1777 + the old -sj, but when set greater than 1, spawns multiple ray
1778 + samples from semi-specular surfaces.
1779 +
1780 + Fixed bug noticed by Randolph Fritz that caused ambient sync errors.
