| 2055 | > | Hopeful fix to deadlock issue under Mac OS X 10.10.x (Yosemite). |

| 2060 | > | ================================= | 
| 2061 | > | Version 5.1 (Released 8/17/2017) | 
| 2062 | > |  | 
| 2063 | > | Fixed issue with vchars.mta and symbols.mta not being installed in | 
| 2064 | > | the appropriate metafile library location, with help from Rob G. | 
| 2065 | > |  | 
| 2066 | > | Added ability to give quoted strings to output= directive in rfluxmtx. | 
| 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 | > | ========================= | 
| 2160 | > | Version 5.2 | 
| 2161 | > |  | 
| 2162 | > | Created psketch program to apply non-photorealistic rendering to selected | 
| 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. | 
| 2169 | > |  | 
| 2170 | > | Falsecolor legend changes and improvements by David G-M and Stephen W. | 
| 2171 | > |  | 
| 2172 | > | Fixed bug in peak extraction code that generated | 
| 2173 | > | "Bad call to SDqueryTreProjSA" error, reported by Lars Grobe. | 
| 2174 | > |  | 
| 2175 | > | Increased maximum luminance to 10^7 in pcond to fix issue noticed | 
| 2176 | > | by Axel Jacobs where veiling glare not added for the sun under | 
| 2177 | > | some conditions. | 
| 2178 | > |  | 
| 2179 | > | Increased maximum number of open files in rcontrib to the system upper | 
| 2180 | > | limit of 2048 rather than the default 512 under Windows. | 
| 2181 | > |  | 
| 2182 | > | Added top-level resources directory with files from Rob Guglielmetti. | 
| 2183 | > |  | 
| 2184 | > | Improved accuracy for peaky BSDFs and small light sources. | 
| 2185 | > |  | 
| 2186 | > | Fixed issue with pmapdump noted by Axel Jacobs. | 
| 2187 | > |  | 
| 2188 | > | Improved accuracy of bsdf2ttree when converting scattering interpolation | 
| 2189 | > | representatons with strong peaks. | 
| 2190 | > |  | 
| 2191 | > | Tweaked peak-extraction code to work more reliably. | 
| 2192 | > |  | 
| 2193 | > | Georg Mischler updated SCons build system. | 
| 2194 | > |  | 
| 2195 | > | Rob Guglielmetti and Alex Swindler updated CMake build system. |
