| 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 | 
| 1749 |  |  | 
| 1750 |  | Fixed bug in genklemsamp that caused non-uniform sampling over surfaces. | 
| 1751 |  |  |

| 1755 |  |  | 
| 1756 |  | ****** COMPATIBILITY CHANGE ******** | 
| 1757 |  | Changed behavior of rtrace and rtcontrib so that every scanline is | 
| 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. | 
| 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. | 
| 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. |
