+Added "-c" option to getinfo to execute command on data segment.
-<
+=====================
-<
+Version 4.3
->
+================================
->
+Version 5.0 (Released 9/18/2015)
+Changed rmtxop so it writes out same type as lesser of inputs unless
-<
+direction otherwise using -f? option.
->
+directed otherwise using -f? option.
+Changed order of oconv arguments in rfluxmtx so user can specify input
+octree using -i option at the end instead of (or in addition to) a
+Fixed bug in indirect hemisphere sampling for some corner cases.
+Added default specular lobe to BSDF interpolation.
-+
-+
+Set minimum number of shadow checks before direct optimization (4).
-+
-+
+(Above changes included in 4.2.1 patch release.)
-+
-+
+****** COMPATIBILITY CHANGE ********
-+
+Made header input and output the default behavior for dctimestep and
-+
+genskyvec.
-+
-+
+****** COMPATIBILITY CHANGE ********
-+
+Changed pabopto2bsdf default behavior to add 90-degree rotation
-+
+to bring pgII's definition of "up" in line with Klems axis
-+
+conventions.  Introduced a new header variable "upphi" to
-+
+control this added rotation.  Using "#upphi 90" in each
-+
+BSDF input file gets back the original behavior, where it
-+
+assumes that the up direction is 90-degrees from the X-axis.
-+
+The default value of 0 corresponds to PAB's definition of
-+
+the X-axis as being "up".
-+
-+
+Fixed bug in rsensor related to having many rows (altitude) and
-+
+few columns (azimuth) in sensitivity file.
-+
-+
+Fixed floating point round-off error in new Hessian calculation
-+
+for some sytems (Windows, primarily).
-+
-+
+Fixed bug in tensor tree BSDF code that caused bus error on
-+
+some systems, and may have been source of other errors as well.
-+
-+
+(Above changes included in 4.2.2 patch release.)
-+
-+
+Improved ambient extrapolation to avoid zero values.  Actual
-+
+threshold set to 5% of recorded value.
-+
-+
+Changed anisotropic Gaussian and Ashikhmin models so that
-+
+illegal orientation vectors are dealt with more gracefully.
-+
-+
+Created wrapBSDF tool and incorporated into genBSDF along
-+
+with new rfluxmtx computation.
-+
-+
+Initial check-in of Roland Schregle's photon map integration.
-+
+New 5.0a version designation as suggested by Andy McNeil.
-+
-+
+Added left-hand coordinate sytems to rfluxmtx to correct
-+
+problems with coordinate axis orientations pointed out by
-+
+David Geisler-Moroder.
-+
-+
+Added color output to genBSDF (+C option) and support for
-+
+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.
-+
-+
+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.
