Added color output to genBSDF (+C option) and support for -color rendering of Klems data. +color rendering of Klems and tensor tree data. + +Fixed another bug in rsensor that caused rays to be generated +on opposite side of hemisphere even where sensitivity was zero. + +Fixed bug discovered by Jacob Jonsson in Klems BSDF +interpolator that caused it to over-predict normal +transmittance and reflectance. + +Added ability to read input from commands in dctimestep +and rmtxop. + +Added photon map support to rad. Fixed some double-counting +issues in photon-mapping spotted by David Geisler-Moroder. + +Added photon map support to trad. + +Fixed bug in antimatter source testing when antimatter +definition follows potential obstructor in input. + +Fixed issue with missing character type identifier at head +of genBSDF XML output. + +Prompted by Roland S., added option to have pcompos -a order +rows from top rather than bottom of image. + +Changed dctimestep to accept matrix as well as BTDF input +in the VTDs invocation mode. This permits the output of +rmtxop to be used in a pinch when combining multiple BTDF +layers, although interreflection between layers is not +accounted for properly as it is in the WINDOW program. + +Added Jan Wienold et al.'s evalglare to distribution. + +Hopeful fix to deadlock issue under Mac OS X 10.10.x (Yosemite). + +Fixed early exit of rcontrib with internal error (sample behind sender) +discovered by Rob G. + +================================= +Version 5.1 (Released 8/17/2017) + +Fixed issue with vchars.mta and symbols.mta not being installed in +the appropriate metafile library location, with help from Rob G. + +Added ability to give quoted strings to output= directive in rfluxmtx. + +****** COMPATIBILITY CHANGE ******** +Added ability to digest color (CIE-XYZ) input in pabopto2bsdf. +This change alters the .sir (interpolant) format, so these files +will need to be regenerated. Use the new "#colorimetry: CIE-XYZ" tag +to enable on input. + +Rewrote bsdf2klems to support tristimulus color and call wrapBSDF. +Did the same for bsdf2ttree. Function specifications still gray only. + +Reduced a problem where rvu or rholo would be slow to quit when +run with many processes on a large model or one with a large +ambient file (taking lots of memory). We were waiting for +processes to quit one-by-one, which takes some time for each +process as it disentangles its shared memory. We now +wait for all the processes together, so they can disentangle +in parallel. It can still take up to a minute in some cases, +but not 10 minutes like it was taking before the fix. + +Enabled ambient cache value corral for all levels, not just final two. +This may reduce errors in certain pathological scenes. + +Added -in option to rcalc, rlam, and total to limit the number of +input records in hopes of circumventing Windows EOF issues on binary data. +Also added -on option to rcalc and total for logical symmetry. + +Increased modifier limit to 10,000 in rcontrib. + +Fixed issues with glrad and added zoom response to mouse wheel input. + +Added missing definition of "ashik2" material type to reference manual. + +Changed genBSDF to calculate device thickness assuming Zmax==0 so +pkgBSDF will generate correct proxy geometry. + +Created pabopto2xyz tool to combine different sensor measurements +into a single CIE-XYZ measurement file for color BSDF interpolation. + +Jan Wienold updated evalglare to version 1.30 + +Roland Schregle added out-of-core photon mapping routines, which +may be compiled using the PMAP_OOC macro. + +Added -a option to getinfo for easy addition of header lines. + +Fixed issue with multiple records on picture output in rcontrib (and rfluxmtx). +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 + +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.
