| 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 (Release October 8, 2018) | 
| 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. | 
| 2214 | > |  | 
| 2215 | > | Worked with Randolph Fritz to fix some issues with ies2rad and newer | 
| 2216 | > | IESNA63 standards. | 
| 2217 | > |  | 
| 2218 | > | Resurrected original bsdf2rad test program, renaming it bsdf2rado. Still an | 
| 2219 | > | optional build in src/cv/. | 
| 2220 | > |  | 
| 2221 | > | Fixed bug in rcontrib with virtual sources, where pretest was adding | 
| 2222 | > | to modifier accumulation buffers.  Reported by Mostapha. | 
| 2223 | > |  | 
| 2224 | > | Added an "aBSDF" material type that explicitly checks for peak extraction. | 
| 2225 | > | Its arguments are the same as the original "BSDF" type, but without the | 
| 2226 | > | thickness parameter, as proxy geometry is not supported by this new type. | 
| 2227 | > | The old "BSDF" type no longer does peak extraction under any circumstances, | 
| 2228 | > | since this behavior is superfluous for proxied geometry. | 
| 2229 | > |  | 
| 2230 | > | Added -r option to bsdf2rad (and bsdfview) to fix BSDF min and max range | 
| 2231 | > | for comparing BSDFs. | 
| 2232 | > |  | 
| 2233 | > | Fixed issue with pfilt -m option and uneven image size changes pointed | 
| 2234 | > | out by Rob Shakespeare. | 
| 2235 | > |  | 
| 2236 | > | Updates to evalglare and gendaylit from Jan Wienold, including new | 
| 2237 | > | colored sky option. | 
| 2238 | > |  | 
| 2239 | > | ========================= | 
| 2240 | > | Version 5.3 | 
| 2241 | > |  | 
| 2242 | > | Created radcompare program to compare Radiance tool output to reference outputs | 
| 2243 | > | during unit-testing. | 
| 2244 | > |  | 
| 2245 | > | Fixed issue reading very large files (> 2 GBytes) in rcollate. | 
| 2246 | > |  | 
| 2247 | > | Made picking function in rvu ignore transparent and void surfaces. | 
| 2248 | > |  | 
| 2249 | > | Added -orRxX options to rtrace to enable output of mirrored and unmirrored | 
| 2250 | > | contributions and distances to enable new types of reprojections.  This also | 
| 2251 | > | cleaned up and unified handling of effective ray lengths throughout code. | 
| 2252 | > |  | 
| 2253 | > | Bug fixes from Jan Wienold for evalglare. | 
| 2254 | > |  | 
| 2255 | > | Changed indexed (numbered) output from dctimestep to start from 0 rather | 
| 2256 | > | than 1, to make it more consistent with expected input naming. | 
| 2257 | > |  | 
| 2258 | > | Increased default sampling in bsdf2klems (-n option) to 1024. | 
| 2259 | > |  | 
| 2260 | > | Fixed an issue noticed by David G-M that was causing genBSDF to bias | 
| 2261 | > | isotropic tensor tree samples resulting in subsequent failure of | 
| 2262 | > | peak extraction with "aBSDF" type. | 
| 2263 | > |  | 
| 2264 | > | Introduced max() and min() functions to .cal library. | 
| 2265 | > |  | 
| 2266 | > | Added random incident patch sampling to bsdf2klems to improve accuracy | 
| 2267 | > | with scattering interpolation representation input (e.g., from | 
| 2268 | > | pabopto2bsdf).  The other input types already sampled incident patch area. | 
| 2269 | > |  | 
| 2270 | > | Added gendaymtx -A option to compute average sky over all the input | 
| 2271 | > | time steps. |
