| 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. | 
| 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. | 
| 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. |
