# Line 1957 | Line 1957 | to klems_full.cal in the process.)
1957   Added "-c" option to getinfo to execute command on data segment.

1959   =====================
1960 < Version 4.3
1960 > Version 5.0
1961  
1962   Changed rmtxop so it writes out same type as lesser of inputs unless
1963 < direction otherwise using -f? option.
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

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.
2046 +
2047 + Changed dctimestep to accept matrix as well as BTDF input
2048 + in the VTDs invocation mode.  This permits the output of
2049 + rmtxop to be used in a pinch when combining multiple BTDF
2050 + layers, although interreflection between layers is not
2051 + accounted for properly as it is in the WINDOW program.
2052 +
2053 + Added Jan Wienold et al.'s evalglare to distribution.
