# 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 2115 | Line 2115 | Credit to Sarith Subramaniam for pointing out the prob
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 (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.
