| 1960 | > | Version 5.0 (Released 9/18/2015) | 
| 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 | 
| 1967 |  | list of scene files. | 
| 1968 |  |  | 
| 1969 | < | Added support for argument expansion to rfluxmtx. | 
| 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). |

| 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). |

| 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. | 
| 2054 | > |  | 
| 2055 | > | Hopeful fix to deadlock issue under Mac OS X 10.10.x (Yosemite). | 
| 2056 | > |  | 
| 2057 | > | Fixed early exit of rcontrib with internal error (sample behind sender) |

| 2067 | > |  | 
| 2068 | > | ****** COMPATIBILITY CHANGE ******** | 
| 2069 | > | Added ability to digest color (CIE-XYZ) input in pabopto2bsdf. | 
| 2070 | > | This change alters the .sir (interpolant) format, so these files | 
| 2071 | > | will need to be regenerated.  Use the new "#colorimetry: CIE-XYZ" tag | 
| 2072 | > | to enable on input. | 
| 2073 | > |  | 
| 2074 | > | Rewrote bsdf2klems to support tristimulus color and call wrapBSDF. | 
| 2075 | > | Did the same for bsdf2ttree.  Function specifications still gray only. | 
| 2076 | > |  | 
| 2077 | > | Reduced a problem where rvu or rholo would be slow to quit when | 
| 2078 | > | run with many processes on a large model or one with a large | 
| 2079 | > | ambient file (taking lots of memory).  We were waiting for | 
| 2080 | > | processes to quit one-by-one, which takes some time for each | 
| 2081 | > | process as it disentangles its shared memory.  We now | 
| 2082 | > | wait for all the processes together, so they can disentangle | 
| 2083 | > | in parallel.  It can still take up to a minute in some cases, | 
| 2084 | > | but not 10 minutes like it was taking before the fix. | 
| 2085 | > |  | 
| 2086 | > | Enabled ambient cache value corral for all levels, not just final two. | 
| 2087 | > | This may reduce errors in certain pathological scenes. | 
| 2088 | > |  | 
| 2089 | > | Added -in option to rcalc, rlam, and total to limit the number of | 
| 2090 | > | input records in hopes of circumventing Windows EOF issues on binary data. | 
| 2091 | > | Also added -on option to rcalc and total for logical symmetry. | 
| 2092 | > |  | 
| 2093 | > | Increased modifier limit to 10,000 in rcontrib. | 
| 2094 | > |  | 
| 2095 | > | Fixed issues with glrad and added zoom response to mouse wheel input. | 
| 2096 | > |  | 
| 2097 | > | Added missing definition of "ashik2" material type to reference manual. | 
| 2098 | > |  | 
| 2099 | > | Changed genBSDF to calculate device thickness assuming Zmax==0 so | 
| 2100 | > | pkgBSDF will generate correct proxy geometry. | 
| 2101 | > |  | 
| 2102 | > | Created pabopto2xyz tool to combine different sensor measurements | 
| 2103 | > | into a single CIE-XYZ measurement file for color BSDF interpolation. | 
| 2104 | > |  | 
| 2105 | > | Jan Wienold updated evalglare to version 1.30 | 
| 2106 | > |  | 
| 2107 | > | Roland Schregle added out-of-core photon mapping routines, which | 
| 2108 | > | may be compiled using the PMAP_OOC macro. | 
| 2109 | > |  | 
| 2110 | > | Added -a option to getinfo for easy addition of header lines. | 
| 2111 | > |  | 
| 2112 | > | Fixed issue with multiple records on picture output in rcontrib (and rfluxmtx). | 
| 2113 | > | Credit to Sarith Subramaniam for pointing out the problem. | 
| 2114 | > |  | 
| 2115 | > | Made mkillum more tolerant of non-planar polygons in its sampling routines. | 
| 2116 | > |  | 
| 2117 | > | Added "-recover" option to genBSDF to pick up where it left off. | 
| 2118 | > |  | 
| 2119 | > | Fixed genBSDF issue that was created incorrect normalization of | 
| 2120 | > | Klems output.  Thanks to David G-M and Christian Knoflach for | 
| 2121 | > | discovering the error.  Also improved sampling of indirect irradiance | 
| 2122 | > | that showed some slight bias due to poor sample collision avoidance. | 
| 2123 | > |  | 
| 2124 | > | Fixed long-standing issue with -aa 0 neglecting textures in calculating | 
| 2125 | > | surface shading. | 
| 2126 | > |  | 
| 2127 | > | Fixed bug in ranimove introduced during photon map integration. | 
| 2128 | > |  | 
| 2129 | > | Added check for steep sections of BSDF in pabopto2bsdf, creating narrower | 
| 2130 | > | peakes in those places and mitigating some normalization issues. | 
| 2131 | > |  | 
| 2132 | > | Added view360stereo.cal by Mark Stock to handle 360-degree over/under | 
| 2133 | > | stereo views. | 
| 2134 | > |  | 
| 2135 | > | Added MAX2SHADE macro to place limit on number of light sources | 
| 2136 | > | to precheck for obstructions.  (Currently set to 200.)  This | 
| 2137 | > | avoids excessive start-up times for scenes with many light sources. | 
| 2138 | > | Thanks to Axel Jacobs for pointing out the problem. | 
| 2139 | > |  | 
| 2140 | > | Added -v option to obj2mesh to print out mesh statistics. | 
| 2141 | > |  | 
| 2142 | > | Rewrote bsdf2rad from ground up and made it a standard part of build. | 
| 2143 | > |  | 
| 2144 | > | Fixed bug in orientation of Reinhart/Tregenza sample generator in rfluxmtx. | 
| 2145 | > |  | 
| 2146 | > | Added ability to perform shadow-testing through unproxied BSDFs with strong | 
| 2147 | > | through (direct-direct) component. | 
| 2148 | > |  | 
| 2149 | > | Added {+|-}a options to genBSDF and bsdf2ttree for switching off reciprocity | 
| 2150 | > | averaging. | 
| 2151 | > |  | 
| 2152 | > | Added bias to see through BTDFs with a strong "through" component | 
| 2153 | > | rather than scattering view rays.  This is in lieu of peak extraction, | 
| 2154 | > | which looked to be too difficult from an implementation standpoint. | 
| 2155 | > |  | 
| 2156 | > | Added bsdfview tool analogous to objview but for BSDF files (XML and SIR), | 
| 2157 | > | which calls bsdf2rad then rad with a few useful default views. | 
| 2158 | > |  | 
| 2159 | > | ========================= |

| 2163 | > | objects, identified by modifier name(s). | 
| 2164 | > |  | 
| 2165 | > | Added '*' and '/' operations to rmtxop for element-wise multiplication and | 
| 2166 | > | division of same-sized matrices. | 
| 2167 | > |  | 
| 2168 | > | Changed falsecolor so "-s" option is adjusted to match legend if one. |
