# 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 1789 | Line 1789 | Added BSDF data-driven material type with full samplin
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.
1829 +
1830 + Added -c option to vwrays to repeat pixels for rtcontrib.
1831 +
1832 + Reworked rtcontrib program and renamed to rcontrib.  New version runs much
1833 + faster, especially on multiprocessor systems, and doesn't require as much
1834 + memory.  No longer calls rtrace; instead does all the work itself.
1835 +
1836 + Added -d option to genskyvec to produce direct-only (sun no sky) vector.
1837 +
1838 + Added Ashikhmin-Shirley anisotropic BRDF model (ashik2) with help
1839 + from Nicolas Boneel.
1840 +
1841 + Added Ruby rewrite of objview.csh by Rob Guglielmetti.
