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. | 
| 1935 | 
+ | 
 | 
| 1936 | 
+ | 
Added header variables for NROWS, NCOLS and NCOMP to help standardize | 
| 1937 | 
+ | 
matrix files.  This functionality has been incorporated into | 
| 1938 | 
+ | 
rcollate, gendaymtx, and dctimestep. | 
| 1939 | 
+ | 
 | 
| 1940 | 
+ | 
Created rmtxop utility to operate on multi-component matrices.  This | 
| 1941 | 
+ | 
facilitates some daylight matrix calculations, and provides a general | 
| 1942 | 
+ | 
tool for manipulating matrix data. | 
| 1943 | 
+ | 
 | 
| 1944 | 
+ | 
****** COMPATIBILITY CHANGE ******** | 
| 1945 | 
+ | 
Introduced new Hessian-based error control in irradiance caching (ambient) | 
| 1946 | 
+ | 
calculation.  Since the format of the stored ambient values is different, | 
| 1947 | 
+ | 
the old files will be rejected with an error message and must be removed. | 
| 1948 | 
+ | 
The programs may be compiled with the -DOLDAMB option if this is a problem. | 
| 1949 | 
+ | 
 | 
| 1950 | 
+ | 
Added -p option to rcontrib to set function file parameters on a per-modifier | 
| 1951 | 
+ | 
basis to simplify bin evaluation. | 
| 1952 | 
+ | 
 | 
| 1953 | 
+ | 
Created rfluxmtx program to compute flux transfer matrices from a sender | 
| 1954 | 
+ | 
surface to one or more receiver surfaces.  (Renamed the file klems_int.cal | 
| 1955 | 
+ | 
to klems_full.cal in the process.) |
