| 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.) | 
| 1886 | + |  | 
| 1887 | + | Fixed bug in isotropic tensor tree sampling for impinging rays | 
| 1888 | + | exactly normal to surface.  Thanks to Peter Apian-Bennewitz for | 
| 1889 | + | discovering and pointing out the error. | 
| 1890 | + |  | 
| 1891 | + | Fixed double-counting bug in mirror material with alternate type. | 
| 1892 | + | Thanks to David Geisler-Moroder for spotting the problem and helping | 
| 1893 | + | to fix it. | 
| 1894 | + |  | 
| 1895 | + | Created rcollate program to resize and transpose matrix data for Andy | 
| 1896 | + | McNeil's 5-phase annual simulation method. | 
| 1897 | + |  | 
| 1898 | + | Added epw2wea conversion program by Christoph Reinhart. | 
| 1899 | + |  | 
| 1900 | + | Implemented Perlin's improved noise function with help from Rahul Narain. | 
| 1901 | + | This will change the appearance of renderings using this function. | 
| 1902 | + |  | 
| 1903 | + | Added "origin" command to rvu as requested by John Mardaljevic | 
| 1904 | + | to place view origin at selected point in scene. | 
| 1905 | + |  | 
| 1906 | + | Switch to Perl versions of objview and objpict written by Axel Jacobs. | 
| 1907 | + |  | 
| 1908 | + | Improved rendering speed of scenes with aliases by not entering new | 
| 1909 | + | modifiers into table if they are the same as the previously defined | 
| 1910 | + | modifier for that name. | 
| 1911 | + |  | 
| 1912 | + | Made it so icalc and rcalc search RAYPATH directories for *.cal files | 
| 1913 | + | given on command line.  This simplifies script writing and makes these | 
| 1914 | + | utilities consistent with other tools in Radiance. | 
| 1915 | + |  | 
| 1916 | + | Added triangulation routine to handle convex polygons in obj2mesh. | 
| 1917 | + |  | 
| 1918 | + | ****** COMPATIBILITY CHANGE ******** | 
| 1919 | + | Made backface visibility apply to all material types, including | 
| 1920 | + | transparent and translucent materials (except dielectric and interface). | 
| 1921 | + | This makes the option useful in cases where adjacent trans surfaces | 
| 1922 | + | are placed next to each other by a modeler that only understands | 
| 1923 | + | volumetric objects. |
