# Line 1971 | Line 1971 | Added support for argument expansion to rfluxmtx and b
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 + ===================
2005 + Version 5.0
2006 +
2007 + Improved ambient extrapolation to avoid zero values.  Actual
2008 + threshold set to 5% of recorded value.
2009 +
2010 + Changed anisotropic Gaussian and Ashikhmin models so that
2011 + illegal orientation vectors are dealt with more gracefully.
2012 +
2013 + Created wrapBSDF tool and incorporated into genBSDF along
2014 + with new rfluxmtx computation.
2015 +
2016 + Initial check-in of Roland Schregle's photon map integration.
2017 + New 5.0a version designation as suggested by Andy McNeil.
2018 +
2019 + Added left-hand coordinate sytems to rfluxmtx to correct
2020 + problems with coordinate axis orientations pointed out by
2021 + David Geisler-Moroder.
2022 +
2023 + Added color output to genBSDF (+C option) and support for
2024 + color rendering of Klems and tensor tree data.
2025 +
2026 + Fixed bug discovered by Jacob Jonsson in Klems BSDF
2027 + interpolator that caused it to over-predict normal
2028 + transmittance and reflectance.
