# Line 1720 | Line 1720 | Added -n option to rtrace for executing on multiple co
1720   using new rayfifo calls.
1721  
1722   =====================
1723 < Version 4.1
1723 > Version 4.1 (Released 11/04/2011)
1724  
1725   Changed ranimate behavior so remote login under a different user
1726   doesn't necessarily require the presence of the originating user's
# Line 1783 | Line 1783 | Fixed bug in findglare for reading picture files under
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.
1798 +
1799 + Muted warning for "no light sources found" when there is at least
1800 + one glow object and interreflections are on (-ab > 0).
1801 +
1802 + Fixed long-standing bug that caused underestimation of reflection
1803 + when specular component was below -st threshold in non-metals.
1804 +
1805 + Checked in cross-platform cmake build system created by Bill Hoffman
1806 + of KitWare and sponsored by NREL.  This includes a qt-based
1807 + driver for rvu, which is built in the new subdirectory src/qtrvu.
1808 +
1809 + =====================
1810 + Version 4.2
1811 +
1812 + Axel Jacobs added -cp and -palettes options to falsecolor.
1813 +
1814 + Fixed bug in matrix output of genBSDF introduced shortly before 4.1 release.
1815 +
1816 + Made rvu more responsive in multi-processing mode when changing parameters.
1817 + Explicit "new" command not needed to show changes, because it goes back
1818 + to "immediate mode" once something is changed.  Processing will be slow
1819 + but response time quick until next "new" command.
1820 +
1821 + Fixed major bug in transmitting proxy material sampling.
1822 +
1823 + Patched cmake build tools (changes by Zack Galbreath).
1824 +
1825 + Removed requirement for pflip -h to be given input file (can pipe from stdin).
1826 +
1827 + Added "Number of processes" slider to trad "Action" pane to control rad -N
1828 + option for rvu and batch rendering.
