| 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. | 
| 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. |
