Fixed bug in reciprocity for tensor tree BTDF representations.  Thanks | 
| 1844 | 
  | 
to Andy McNeil for identifying the problem. |

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 |

****** 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.) | 
| 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. | 
| 1924 | 
+ | 
 | 
| 1925 | 
+ | 
Changed dctimestep so that output matrices (-n > 1) are preceded by a | 
| 1926 | 
+ | 
header, and added support for float and double output formats with -o[fd]. | 
| 1927 | 
+ | 
 | 
| 1928 | 
+ | 
Introduced eplus_adduvf program to compute user view factors for EnergyPlus. | 
| 1929 | 
+ | 
 | 
| 1930 | 
+ | 
Changed image-plane sampling in rpict to use Hilbert curve, which gives | 
| 1931 | 
+ | 
less of a brushed/striped appearance to output pixels with -u- (default). | 
| 1932 | 
+ | 
 | 
| 1933 | 
+ | 
Added ltview and ltpict Perl scripts contributed by Axel Jacobs, inspired | 
| 1934 | 
+ | 
by Rob Guglielmetti. |
