# Line 2058 | Line 2058 | Fixed early exit of rcontrib with internal error (samp
2058   discovered by Rob G.
2059  
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.
# Line 2098 | Line 2098 | Added missing definition of "ashik2" material type to
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.
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.
