| 2060 |  | ================================= | 
| 2061 | < | Version 5.1 | 
| 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. | 
| 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 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. |

| 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. | 
| 2196 | > |  | 
| 2197 | > | Modified pcomb so the first view seen in the inputs is written into header. | 
| 2198 | > |  | 
| 2199 | > | Wrote rtpict script to run rtrace in parallel mode and simulate rpict with | 
| 2200 | > | -n option. | 
| 2201 | > |  | 
| 2202 | > | Added ability to move forwards/backwards specified distance in rvu "origin" | 
| 2203 | > | command.  Feature requested by John Mardaljevic, who essentially owns this | 
| 2204 | > | command, now. | 
| 2205 | > |  | 
| 2206 | > | Reduced bias in ambient super-sampling method. | 
| 2207 | > |  | 
| 2208 | > | Fixed bugs associated with zero transmission in chromatic tensor trees. | 
| 2209 | > | Thanks to Lars Grobe for pointing out issues. | 
| 2210 | > |  | 
| 2211 | > | Added RAYPATH searching for -f options to genrev, gensurf, genworm, | 
| 2212 | > | bsdf2klems, bsdf2ttree, and pcomb.  This makes behavior consistent | 
| 2213 | > | with rcalc, calc, and rendering tools. |
