# 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 1621 | Line 1621 | Additional error-checking for source surfaces.
1621   Re-fixed bug in octree code that caused it to allocate 8 times as
1622   much memory as it actually used(!) -- this was pointed out way back
1623   in 1999 by Erik Reinhard and Erik Jansen, but the fix they gave me
1624 < got lost in the slightly borken release process at the time.  This
1624 > got lost in the slightly broken release process at the time.  This
1625   should make a big difference in memory usage, especially for the
1626   new mesh primitive.  (I measured 30% less memory usage.)
1627  
# Line 1633 | Line 1633 | of the smaller octree structure size.
1633   Fixed bug in shadow cache where it was adding surfaces with antimatter
1634   holes cut in them to the obstructor list.  Thanks to John Mardaljevic
1635   for discovering and reporting the problem.
1636 +
1637 + Adding ability in mkillum to incorporate BSDF data in calculation.
1638 + Internal interface (raypcalls) now used in place of rtrace process(es).
1639 +
1640 + Fixed pixel alignment in pcomb for size reduction and enlargement.
1641 +
1642 + Allow rtcontrib user to set -P and -PP options for persistent rendering.
1643 + The only caveat is that -n setting > 1 requires -PP rather than -P.
1644 +
1645 + Added -c option to rtcontrib to facilitate cumulative calculations.
1646 +
1647 + ****** COMPATIBILITY CHANGE ********
1648 + Fixed long-standing bug in source.cal, which caused it to produce
1649 + reversed anisotropic photometric distributions due to the
1650 + misorientation of the y-axis.  Thanks to Zack Rogers for discovering
1651 + and helping debug this problem.
1652 +
1653 + Fixed long-standing bug in replmarks, where triangles with X-side
1654 + aligned with Z-axis would cause incorrect rotations.  Thanks to
1655 + Zack Rogers for finding this error.
1656 +
1657 + Added rsensor program to compute sensor signal for daylighting controls.
1658 + Funding for this component was provided by the Architectural Energy
1659 + Corporation in Boulder, CO, and directed by Zack Rogers.
1660 +
1661 + Added "planisphere" (stereographic) fisheye view type for traditional
1662 + daylighting analysis.  Feature requested & explained by Axel Jacobs.
1663 +
1664 + Modified -c option to rtcontrib so it can take a number of input
1665 + rays to average over, rather than only produce a single accumulated
1666 + record (which can now be done with -c 0).
1667 +
1668 + =====================
1669 + Version 4.0 (Released 3/12/10)
1670 +
1671 + Added -n option to rvu to provide parallel rendering.
1672 +
1673 + ****** COMPATIBILITY CHANGE ********
1674 + Changed ".pic" extension to ".hdr" in all sources and documentation
1675 + to improve interoperability with other software, since this has become
1676 + the de facto extension for Radiance RGBE and XYZE pictures.  Since file
1677 + extensions were never more than a convention in Radiance, this does not
1678 + affect operation, but may require the update of scripts, etc. written
1679 + by others that assume the ".pic" suffix for Radiance output.
1680 +
1681 + Added -N option to objview to support multiprocessing.
1682 +
1683 + Improved sampling of circular sources (source, sphere, ring types) with
1684 + quite a bit of help from David Geisler-Moroder.
1685 +
1686 + Added "rpict" and "rvu" variables to rad, and made these as well as
1687 + the "oconv", "mkillum" and "pfilt" variables accept an alternate
1688 + command path in each case.  Change suggested by Lars Grobe based
1689 + on similar Radzilla (radz) facility by Carsten Bauer.
1690 +
1691 + Fixed rad -v N specification to use actual view name if one.
1692 +
1693 + Fixed error in mkillum calculation where it neglected indirect
1694 + source contributions from BTDF illum's.
1695 +
1696 + Added GMT and LATLONG header lines for Greenwich Mean Time and
1697 + degrees North Latitude / East Longitude.
1698 +
1699 + Added gendaylit to distribution (finally).
1700 +
1701 + Added ability in vwright(1) to get view from command line arguments.
1702 +
1703 + Created genklemsamp(1) utility to generate samples suitable for
1704 + BSDF-based annual calculations.  This is the first Perl script to
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.
