# Line 1720 | Line 1720 | Added -n option to rtrace for executing on multiple co

1723 > Version 4.1 (Released 11/04/2011)

1725   Changed ranimate behavior so remote login under a different user
1726   doesn't necessarily require the presence of the originating user's
# Line 1805 | Line 1805 | when specular component was below -st threshold in non
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.
1842 +
1843 + Fixed bug in reciprocity for tensor tree BTDF representations.  Thanks
1844 + to Andy McNeil for identifying the problem.
1845 +
1846 + Added MNAME and ZNAME variables to ranimove for debugging & testing.
1847 +
1848 + Created pmblur2 command to take motion and depth buffers from ranimove
1849 + to compute a better motion blur.
1850 +
1851 + ****** COMPATIBILITY CHANGE ********
1852 + Changed BSDF routines to use updated/corrected XML specification and
1853 + removed depracated BSDF support from mkillum.
1854 +
1855 + Fixed behavior of i/o flushing in rcontrib with -c > 1 (averaging).  Thanks
1856 + to Lars Grobe for help identifying this problem.
1857 +
1858 + Fixed bug in depth-of-field blur where view distance was measured from
1859 + fore clipping plane rather than viewpoint.  Thanks to Peter A-B for
1860 + pointing this out.
1861 +
1862 + Added options to dctimestep to allow multiple time steps (-n)
1863 + and multiple output pictures or sensor files (-o).  Also added -i
1864 + option to specify float (-if) or double (-id) input for sky matrix.
1865 +
1866 + Created gendaymtx program to compute annual sky patch matrix based
1867 + on Ian Ashdown's implementation of Perez all-weather sky model.
1868 + Output can be sent directly to dctimestep in ASCII or binary stream.
1869 +
1870 + Replaced existing gendaylit.c with improved version from Wendelin Sprenger
1871 + and Jan Wienold of ISE.
1872 +
1873 + Improved accuracy of ambient calculation for large -ad settings.  Thanks
1874 + to Lars Grobe for noticing the problem.
1875 +
1876 + Added -r option to gendaymtx to rotate the sky the specified number of
1877 + degrees about the zenith as suggested by A. McNeil.
1878 +
1879 + Axel Jacobs added -pal eco color map that does a blue-red-yellow scale.
1880 +
1881 + Created bsdf2klems tool to convert from various BSDF representations to
1882 + Klems basis matrix in XML file.
1883 +
1884 + Fixed problem with inappropriate reciprocity enforcement on tensor
1885 + tree reduction in genBSDF.  (Thanks to A.McNeil for discovering issue.)
