# Line 1725 | Line 1725 | Version 4.1
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.
1781 +
1782 + Fixed bug in findglare for reading picture files under Windows.
1783 +
1784 + Added options to pvalue to note other color spaces on reverse conversion.
1785 + Thanks to Erich Philips for the feature request.
1786 +
1787 + Added BSDF data-driven material type with full sampling support.
1788 +
1789 + Added BRDF calculations to genBSDF.
1790 +
1791 + Bug fixes in rsensor thanks to help from David Geisler-Moroder.
1792 +
1793 + Added variable-resolution BSDF support in renderers and genBSDF.
1794 +
1795 + Created pkgBSDF program to extract BSDF geometry and put it
1796 + together with surface description suitable for inclusion in
1797 + a Radiance scene.
