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.

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.
