| 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. | 
| 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 (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. | 
| 2272 | + |  | 
| 2273 | + | Added ability to output color image from rtrace with any of -ovrx options. | 
| 2274 | + | Also fixed inconsistency of -oN output when ray casting versus full trace. | 
| 2275 | + | Before, it would flip normal to front side unless ray casting.  Now, -oN | 
| 2276 | + | always reports the unflipped normal. | 
| 2277 | + |  | 
| 2278 | + | Changed rlam behavior so -iaN reads N lines from a stream rather than N | 
| 2279 | + | characters.  This seems more useful, since -ibN is somewhat redundant with | 
| 2280 | + | the old behavior. | 
| 2281 | + |  | 
| 2282 | + | Created rsplit program as compliment to rlam and to handle more complex | 
| 2283 | + | rtrace output into separate files or streams. | 
| 2284 | + |  | 
| 2285 | + | Improved getinfo so that it can also hop over resolution string with -c | 
| 2286 | + | and header elide mode.  Use +d to include resolution string in output, | 
| 2287 | + | and -d to elide with - and -c options. | 
| 2288 | + |  | 
| 2289 | + | Made pvalue -u option mean "uncompressed" with -r.  Also, allow skipping | 
| 2290 | + | bytes on standard input. | 
| 2291 | + |  | 
| 2292 | + | Created rcode_depth tool to convert to and from a 16-bit/pixel portable | 
| 2293 | + | depth image encoding that uses a mix of linear and reciprocal distance | 
| 2294 | + | with explicit representations of 0 and infinity.  Code for loading these | 
| 2295 | + | depth maps is in src/common/depthcodec.{h,c}. | 
| 2296 | + |  | 
| 2297 | + | Created rcode_norm tool to convert to and from 32-bit/pixel portable | 
| 2298 | + | surface normal representation, matching the one in src/common/dircode.c. | 
| 2299 | + | Code for loading normal maps is in src/common/normcodec.{h,c}. | 
| 2300 | + |  | 
| 2301 | + | Created rcode_ident tool to create indexed identifier files. | 
| 2302 | + | Code for loading these files is in src/common/idmap.{h,c}. | 
| 2303 | + |  | 
| 2304 | + | Added -o* option to rtpict to produce layered images that handle most | 
| 2305 | + | output types from rtrace (colors, surface normals, distances, IDs). | 
| 2306 | + |  | 
| 2307 | + | Created rcode2bmp script to create images from new rcode_* output maps. | 
| 2308 | + |  | 
| 2309 | + | Improved efficiency of rmtxop in cases where matrix multiplication is | 
| 2310 | + | faster evaluated right-to-left, as when the final component is a | 
| 2311 | + | column vector.  Also added ability to apply trailing unary operators | 
| 2312 | + | (-t, and -s or -c) to resulting matrix. | 
| 2313 | + |  | 
| 2314 | + | Added new depth, normal, and ID file types to radcompare. | 
| 2315 | + |  | 
| 2316 | + | Added BigEndian= header line for automatic byte-swapping in rmtxop | 
| 2317 | + | and radcompare.  Doesn't work quite as automatically as it should | 
| 2318 | + | for pvalue -r, currently. | 
| 2319 | + |  | 
| 2320 | + | Added new "turbo" palette to falsecolor (thanks to Taoning). | 
| 2321 | + |  | 
| 2322 | + | Nathaniel Jones created the "dcglare" program for annual glare | 
| 2323 | + | simulations when the sun and sky are visible through the window. | 
| 2324 | + | Tutorial is posted at "https://github.com/nljones/Accelerad/wiki/The-Imageless-Method-for-Spatial-and-Annual-Glare-Analysis". |
