Credit to Sarith Subramaniam for pointing out the problem. + +Made mkillum more tolerant of non-planar polygons in its sampling routines. + +Added "-recover" option to genBSDF to pick up where it left off. + +Fixed genBSDF issue that was created incorrect normalization of +Klems output. Thanks to David G-M and Christian Knoflach for +discovering the error. Also improved sampling of indirect irradiance +that showed some slight bias due to poor sample collision avoidance. + +Fixed long-standing issue with -aa 0 neglecting textures in calculating +surface shading. + +Fixed bug in ranimove introduced during photon map integration. + +Added check for steep sections of BSDF in pabopto2bsdf, creating narrower +peakes in those places and mitigating some normalization issues. + +Added view360stereo.cal by Mark Stock to handle 360-degree over/under +stereo views. + +Added MAX2SHADE macro to place limit on number of light sources +to precheck for obstructions. (Currently set to 200.) This +avoids excessive start-up times for scenes with many light sources. +Thanks to Axel Jacobs for pointing out the problem. + +Added -v option to obj2mesh to print out mesh statistics. + +Rewrote bsdf2rad from ground up and made it a standard part of build. + +Fixed bug in orientation of Reinhart/Tregenza sample generator in rfluxmtx. + +Added ability to perform shadow-testing through unproxied BSDFs with strong +through (direct-direct) component. + +Added {+|-}a options to genBSDF and bsdf2ttree for switching off reciprocity +averaging. + +Added bias to see through BTDFs with a strong "through" component +rather than scattering view rays. This is in lieu of peak extraction, +which looked to be too difficult from an implementation standpoint. + +Added bsdfview tool analogous to objview but for BSDF files (XML and SIR), +which calls bsdf2rad then rad with a few useful default views. + +========================= +Version 5.2 (Release October 8, 2018) + +Created psketch program to apply non-photorealistic rendering to selected +objects, identified by modifier name(s). + +Added '*' and '/' operations to rmtxop for element-wise multiplication and +division of same-sized matrices. + +Changed falsecolor so "-s" option is adjusted to match legend if one. + +Falsecolor legend changes and improvements by David G-M and Stephen W. + +Fixed bug in peak extraction code that generated +"Bad call to SDqueryTreProjSA" error, reported by Lars Grobe. + +Increased maximum luminance to 10^7 in pcond to fix issue noticed +by Axel Jacobs where veiling glare not added for the sun under +some conditions. + +Increased maximum number of open files in rcontrib to the system upper +limit of 2048 rather than the default 512 under Windows. + +Added top-level resources directory with files from Rob Guglielmetti. + +Improved accuracy for peaky BSDFs and small light sources. + +Fixed issue with pmapdump noted by Axel Jacobs. + +Improved accuracy of bsdf2ttree when converting scattering interpolation +representatons with strong peaks. + +Tweaked peak-extraction code to work more reliably. + +Georg Mischler updated SCons build system. + +Rob Guglielmetti and Alex Swindler updated CMake build system. + +Modified pcomb so the first view seen in the inputs is written into header. + +Wrote rtpict script to run rtrace in parallel mode and simulate rpict with +-n option. + +Added ability to move forwards/backwards specified distance in rvu "origin" +command. Feature requested by John Mardaljevic, who essentially owns this +command, now. + +Reduced bias in ambient super-sampling method. + +Fixed bugs associated with zero transmission in chromatic tensor trees. +Thanks to Lars Grobe for pointing out issues. + +Added RAYPATH searching for -f options to genrev, gensurf, genworm, +bsdf2klems, bsdf2ttree, and pcomb. This makes behavior consistent +with rcalc, calc, and rendering tools. + +Worked with Randolph Fritz to fix some issues with ies2rad and newer +IESNA63 standards. + +Resurrected original bsdf2rad test program, renaming it bsdf2rado. Still an +optional build in src/cv/. + +Fixed bug in rcontrib with virtual sources, where pretest was adding +to modifier accumulation buffers. Reported by Mostapha. + +Added an "aBSDF" material type that explicitly checks for peak extraction. +Its arguments are the same as the original "BSDF" type, but without the +thickness parameter, as proxy geometry is not supported by this new type. +The old "BSDF" type no longer does peak extraction under any circumstances, +since this behavior is superfluous for proxied geometry. + +Added -r option to bsdf2rad (and bsdfview) to fix BSDF min and max range +for comparing BSDFs. + +Fixed issue with pfilt -m option and uneven image size changes pointed +out by Rob Shakespeare. + +Updates to evalglare and gendaylit from Jan Wienold, including new +colored sky option. + +========================= +Version 5.3 + +Created radcompare program to compare Radiance tool output to reference outputs +during unit-testing. + +Fixed issue reading very large files (> 2 GBytes) in rcollate. + +Made picking function in rvu ignore transparent and void surfaces. + +Added -orRxX options to rtrace to enable output of mirrored and unmirrored +contributions and distances to enable new types of reprojections. This also +cleaned up and unified handling of effective ray lengths throughout code. + +Bug fixes from Jan Wienold for evalglare. + +Changed indexed (numbered) output from dctimestep to start from 0 rather +than 1, to make it more consistent with expected input naming. + +Increased default sampling in bsdf2klems (-n option) to 1024. + +Fixed an issue noticed by David G-M that was causing genBSDF to bias +isotropic tensor tree samples resulting in subsequent failure of +peak extraction with "aBSDF" type. + +Introduced max() and min() functions to .cal library. + +Added random incident patch sampling to bsdf2klems to improve accuracy +with scattering interpolation representation input (e.g., from +pabopto2bsdf). The other input types already sampled incident patch area. + +Added gendaymtx -A option to compute average sky over all the input +time steps. + +Added ability to output color image from rtrace with any of -ovrx options.
