1724 |
|
|
1725 |
|
Changed ranimate behavior so remote login under a different user |
1726 |
|
doesn't necessarily require the presence of the originating user's |

****** COMPATIBILITY CHANGE ******** |
1757 |
|
Changed behavior of rtrace and rtcontrib so that every scanline is |
1761 |
|
|
1762 |
|
Added ability for rsensor to output ray origins and directions |
1763 |
|
rather than actually loading octree and computing sensor value. |
1764 |
+ |
|
1765 |
+ |
Fixed old bug in obj2rad where it would stop processing and |
1766 |
+ |
report a syntax error if the "void" type is used in the map file. |
1767 |
+ |
|
1768 |
+ |
Updated reflection model according to EGSR 2010 paper by David |
1769 |
+ |
Geisler-Moroder and Arne Duer. |
1770 |
+ |
|
1771 |
+ |
Replaced C-shell version of falsecolor with Perl script written |
1772 |
+ |
by Axel Jacobs. |
1773 |
+ |
|
1774 |
+ |
****** COMPATIBILITY CHANGE ******** |
1775 |
+ |
Changed -sj (specular jitter) option to something called specular |
1776 |
+ |
sampling (-ss), which if set less than 1 has the same behavior as |
1777 |
+ |
the old -sj, but when set greater than 1, spawns multiple ray |
1778 |
+ |
samples from semi-specular surfaces. |
1779 |
+ |
|
1780 |
+ |
Fixed bug noticed by Randolph Fritz that caused ambient sync errors. |
1781 |
+ |
|
1782 |
+ |
Fixed bug in findglare for reading picture files under Windows. |
1783 |
+ |
|
1784 |
+ |
Added options to pvalue to note other color spaces on reverse conversion. |
1785 |
+ |
Thanks to Erich Philips for the feature request. |
1786 |
+ |
|
1787 |
+ |
Added BSDF data-driven material type with full sampling support. |
1788 |
+ |
|
1789 |
+ |
Added BRDF calculations to genBSDF. |
1790 |
+ |
|
1791 |
+ |
Bug fixes in rsensor thanks to help from David Geisler-Moroder. |
1792 |
+ |
|
1793 |
+ |
Added variable-resolution BSDF support in renderers and genBSDF. |
1794 |
+ |
|
1795 |
+ |
Created pkgBSDF program to extract BSDF geometry and put it |
1796 |
+ |
together with surface description suitable for inclusion in |
1797 |
+ |
a Radiance scene. |
1798 |
+ |
|
1799 |
+ |
Muted warning for "no light sources found" when there is at least |
1800 |
+ |
one glow object and interreflections are on (-ab > 0). |
1801 |
+ |
|
1802 |
+ |
Fixed long-standing bug that caused underestimation of reflection |
1803 |
+ |
when specular component was below -st threshold in non-metals. |
1804 |
+ |
|
1805 |
+ |
Checked in cross-platform cmake build system created by Bill Hoffman |
1806 |
+ |
of KitWare and sponsored by NREL. This includes a qt-based |
1807 |
+ |
driver for rvu, which is built in the new subdirectory src/qtrvu. |
1808 |
+ |
|
1809 |

===================== |
1810 |
+ |
Version 4.2 (Release date 7/31/2014) |
1811 |
+ |
|
1812 |
+ |
Axel Jacobs added -cp and -palettes options to falsecolor. |
1813 |
+ |
|
1814 |
+ |
Fixed bug in matrix output of genBSDF introduced shortly before 4.1 release. |
1815 |
+ |
|
1816 |
+ |
Made rvu more responsive in multi-processing mode when changing parameters. |
1817 |
+ |
Explicit "new" command not needed to show changes, because it goes back |
1818 |
+ |
to "immediate mode" once something is changed. Processing will be slow |
1819 |
+ |
but response time quick until next "new" command. |
1820 |
+ |
|
1821 |
+ |
Fixed major bug in transmitting proxy material sampling. |
1822 |
+ |
|
1823 |
+ |
Patched cmake build tools (changes by Zack Galbreath). |
1824 |
+ |
|
1825 |
+ |
Removed requirement for pflip -h to be given input file (can pipe from stdin). |
1826 |
+ |
|
1827 |
+ |
Added "Number of processes" slider to trad "Action" pane to control rad -N |
1828 |
+ |
option for rvu and batch rendering. |
1829 |
+ |
|
1830 |
+ |
Added -c option to vwrays to repeat pixels for rtcontrib. |
1831 |
+ |
|
1832 |
+ |
Reworked rtcontrib program and renamed to rcontrib. New version runs much |
1833 |
+ |
faster, especially on multiprocessor systems, and doesn't require as much |
1834 |
+ |
memory. No longer calls rtrace; instead does all the work itself. |
1835 |
+ |
|
1836 |
+ |
Added -d option to genskyvec to produce direct-only (sun no sky) vector. |
1837 |
+ |
|
1838 |
+ |
Added Ashikhmin-Shirley anisotropic BRDF model (ashik2) with help |
1839 |
+ |
from Nicolas Boneel. |
1840 |
+ |
|
1841 |
+ |
Added Ruby rewrite of objview.csh by Rob Guglielmetti. |
1842 |
+ |
|
1843 |
+ |
Fixed bug in reciprocity for tensor tree BTDF representations. Thanks |
1844 |
+ |
to Andy McNeil for identifying the problem. |
1845 |
+ |
|
1846 |
+ |
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 |
+ |
|
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. |
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. |
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.) |
1956 |
+ |
|
1957 |
+ |
Added "-c" option to getinfo to execute command on data segment. |
1958 |
+ |
|
1959 |
+ |
===================== |
1960 |
+ |
Version 5.0 |
1961 |
+ |
|
1962 |
+ |
Changed rmtxop so it writes out same type as lesser of inputs unless |
1963 |
+ |
directed otherwise using -f? option. |
1964 |
+ |
|
1965 |
+ |
Changed order of oconv arguments in rfluxmtx so user can specify input |
1966 |
+ |
octree using -i option at the end instead of (or in addition to) a |
1967 |
+ |
list of scene files. |
1968 |
+ |
|
1969 |
+ |
Added support for argument expansion to rfluxmtx and bug fixes. |
1970 |
+ |
|
1971 |
+ |
Fixed bug in indirect hemisphere sampling for some corner cases. |
1972 |
+ |
|
1973 |
+ |
Added default specular lobe to BSDF interpolation. |
1974 |
+ |
|
1975 |
+ |
Set minimum number of shadow checks before direct optimization (4). |
1976 |
+ |
|
1977 |
+ |
(Above changes included in 4.2.1 patch release.) |
1978 |
+ |
|
1979 |
+ |
****** COMPATIBILITY CHANGE ******** |
1980 |
+ |
Made header input and output the default behavior for dctimestep and |
1981 |
+ |
genskyvec. |
1982 |
+ |
|
1983 |
+ |
****** COMPATIBILITY CHANGE ******** |
1984 |
+ |
Changed pabopto2bsdf default behavior to add 90-degree rotation |
1985 |
+ |
to bring pgII's definition of "up" in line with Klems axis |
1986 |
+ |
conventions. Introduced a new header variable "upphi" to |
1987 |
+ |
control this added rotation. Using "#upphi 90" in each |
1988 |
+ |
BSDF input file gets back the original behavior, where it |
1989 |
+ |
assumes that the up direction is 90-degrees from the X-axis. |
1990 |
+ |
The default value of 0 corresponds to PAB's definition of |
1991 |
+ |
the X-axis as being "up". |
1992 |
+ |
|
1993 |
+ |
Fixed bug in rsensor related to having many rows (altitude) and |
1994 |
+ |
few columns (azimuth) in sensitivity file. |
1995 |
+ |
|
1996 |
+ |
Fixed floating point round-off error in new Hessian calculation |
1997 |
+ |
for some sytems (Windows, primarily). |
1998 |
+ |
|
1999 |
+ |
Fixed bug in tensor tree BSDF code that caused bus error on |
2000 |
+ |
some systems, and may have been source of other errors as well. |
2001 |
+ |
|
2002 |
+ |
(Above changes included in 4.2.2 patch release.) |
2003 |
+ |
|
2004 |
+ |
Improved ambient extrapolation to avoid zero values. Actual |
2005 |
+ |
threshold set to 5% of recorded value. |
2006 |
+ |
|
2007 |
+ |
Changed anisotropic Gaussian and Ashikhmin models so that |
2008 |
+ |
illegal orientation vectors are dealt with more gracefully. |
2009 |
+ |
|
2010 |
+ |
Created wrapBSDF tool and incorporated into genBSDF along |
2011 |
+ |
with new rfluxmtx computation. |
2012 |
+ |
|
2013 |
+ |
Initial check-in of Roland Schregle's photon map integration. |
2014 |
+ |
New 5.0a version designation as suggested by Andy McNeil. |
2015 |
+ |
|
2016 |
+ |
Added left-hand coordinate sytems to rfluxmtx to correct |
2017 |
+ |
problems with coordinate axis orientations pointed out by |
2018 |
+ |
David Geisler-Moroder. |
2019 |
+ |
|
2020 |
+ |
Added color output to genBSDF (+C option) and support for |
2021 |
+ |
color rendering of Klems and tensor tree data. |
2022 |
+ |
|
2023 |
+ |
Fixed another bug in rsensor that caused rays to be generated |
2024 |
+ |
on opposite side of hemisphere even where sensitivity was zero. |
2025 |
+ |
|
2026 |
+ |
Fixed bug discovered by Jacob Jonsson in Klems BSDF |
2027 |
+ |
interpolator that caused it to over-predict normal |
2028 |
+ |
transmittance and reflectance. |
2029 |
+ |
|
2030 |
+ |
Added ability to read input from commands in dctimestep |
2031 |
+ |
and rmtxop. |
2032 |
+ |
|
2033 |
+ |
Added photon map support to rad. Fixed some double-counting |
2034 |
+ |
issues in photon-mapping spotted by David Geisler-Moroder. |
