| 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 | 
| 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. |
