# Line 1807 | Line 1807 | of KitWare and sponsored by NREL.  This includes a qt-
1807   driver for rvu, which is built in the new subdirectory src/qtrvu.
1808  
1809   =====================
1810 < Version 4.2
1810 > Version 4.2 (Release date 7/31/2014)
1811  
1812   Axel Jacobs added -cp and -palettes options to falsecolor.
1813  
# Line 1883 | Line 1883 | 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.
2035 +
2036 + Added photon map support to trad.
2037 +
2038 + Fixed bug in antimatter source testing when antimatter
2039 + definition follows potential obstructor in input.
2040 +
2041 + Fixed issue with missing character type identifier at head
2042 + of genBSDF XML output.
2043 +
2044 + Prompted by Roland S., added option to have pcompos -a order
2045 + rows from top rather than bottom of image.
