+using new rayfifo calls.
+=====================
-<
+Version 4.1
->
+Version 4.1 (Released 11/04/2011)
+Changed ranimate behavior so remote login under a different user
+doesn't necessarily require the presence of the originating user's
+Changed standard transmission function normalization back to what
+it was in version 3.5, following recommendation of David Geisler-Moroder,
+who pointed out that the revised BTDF increased too much at grazing.
-+
-+
+Changed rad behavior with -N >1 on single view to call rpiece.
-+
-+
+Updated SCons build system for MINGW compilation, thanks to Christian
-+
+Kohler.
-+
-+
+Added -u option to rlam for unbuffered output.
-+
-+
+Modified dctimestep to accept sky vector and daylight coefficient matrix
-+
+or list of images to sum together, as suggested by Andy McNeil.
-+
-+
+Created genBSDF script to generate BSDF in Windows XML format.
-+
-+
+Modified mkillum to accept detailed geometry from BSDF XML files.
-+
-+
+Altered obj2rad to ignore zero normals (thanks to Jack de Valpine for
-+
+suggestions and help).
-+
-+
+Fixed bug in genklemsamp that caused non-uniform sampling over surfaces.
-+
-+
+Fixed bugs in rhoptimize and rhcopy for 64-bit compilation.
-+
-+
+Made a change to avoid problem using gcc --fast-math compile option.
-+
-+
+****** COMPATIBILITY CHANGE ********
-+
+Changed behavior of rtrace and rtcontrib so that every scanline is
-+
+not flushed when both -x and -y are set.  This avoids flush delays
-+
+in rtcontrib for large numbers of output files and delays while
-+
+rendering images using rtrace with the -n option.
-+
-+
+Added ability for rsensor to output ray origins and directions
-+
+rather than actually loading octree and computing sensor value.
-+
-+
+Fixed old bug in obj2rad where it would stop processing and
-+
+report a syntax error if the "void" type is used in the map file.
-+
-+
+Updated reflection model according to EGSR 2010 paper by David
-+
+Geisler-Moroder and Arne Duer.
-+
-+
+Replaced C-shell version of falsecolor with Perl script written
-+
+by Axel Jacobs.
-+
-+
+****** COMPATIBILITY CHANGE ********
-+
+Changed -sj (specular jitter) option to something called specular
-+
+sampling (-ss), which if set less than 1 has the same behavior as
-+
+the old -sj, but when set greater than 1, spawns multiple ray
-+
+samples from semi-specular surfaces.
-+
-+
+Fixed bug noticed by Randolph Fritz that caused ambient sync errors.
-+
-+
+Fixed bug in findglare for reading picture files under Windows.
-+
-+
+Added options to pvalue to note other color spaces on reverse conversion.
-+
+Thanks to Erich Philips for the feature request.
-+
-+
+Added BSDF data-driven material type with full sampling support.
-+
-+
+Added BRDF calculations to genBSDF.
-+
-+
+Bug fixes in rsensor thanks to help from David Geisler-Moroder.
-+
-+
+Added variable-resolution BSDF support in renderers and genBSDF.
-+
-+
+Created pkgBSDF program to extract BSDF geometry and put it
-+
+together with surface description suitable for inclusion in
-+
+a Radiance scene.
-+
-+
+Muted warning for "no light sources found" when there is at least
-+
+one glow object and interreflections are on (-ab > 0).
-+
-+
+Fixed long-standing bug that caused underestimation of reflection
-+
+when specular component was below -st threshold in non-metals.
-+
-+
+Checked in cross-platform cmake build system created by Bill Hoffman
-+
+of KitWare and sponsored by NREL.  This includes a qt-based
-+
+driver for rvu, which is built in the new subdirectory src/qtrvu.
-+
-+
+=====================
-+
+Version 4.2
-+
-+
+Axel Jacobs added -cp and -palettes options to falsecolor.
-+
-+
+Fixed bug in matrix output of genBSDF introduced shortly before 4.1 release.
-+
-+
+Made rvu more responsive in multi-processing mode when changing parameters.
-+
+Explicit "new" command not needed to show changes, because it goes back
-+
+to "immediate mode" once something is changed.  Processing will be slow
-+
+but response time quick until next "new" command.
-+
-+
+Fixed major bug in transmitting proxy material sampling.
-+
-+
+Patched cmake build tools (changes by Zack Galbreath).
-+
-+
+Removed requirement for pflip -h to be given input file (can pipe from stdin).
-+
-+
+Added "Number of processes" slider to trad "Action" pane to control rad -N
-+
+option for rvu and batch rendering.
-+
-+
+Added -c option to vwrays to repeat pixels for rtcontrib.
-+
-+
+Reworked rtcontrib program and renamed to rcontrib.  New version runs much
-+
+faster, especially on multiprocessor systems, and doesn't require as much
-+
+memory.  No longer calls rtrace; instead does all the work itself.
-+
-+
+Added -d option to genskyvec to produce direct-only (sun no sky) vector.
-+
-+
+Added Ashikhmin-Shirley anisotropic BRDF model (ashik2) with help
-+
+from Nicolas Boneel.
-+
-+
+Added Ruby rewrite of objview.csh by Rob Guglielmetti.
-+
-+
+Fixed bug in reciprocity for tensor tree BTDF representations.  Thanks
-+
+to Andy McNeil for identifying the problem.
-+
-+
+Added MNAME and ZNAME variables to ranimove for debugging & testing.
-+
-+
+Created pmblur2 command to take motion and depth buffers from ranimove
-+
+to compute a better motion blur.
-+
-+
+****** COMPATIBILITY CHANGE ********
-+
+Changed BSDF routines to use updated/corrected XML specification and
-+
+removed depracated BSDF support from mkillum.
-+
-+
+Fixed behavior of i/o flushing in rcontrib with -c > 1 (averaging).  Thanks
-+
+to Lars Grobe for help identifying this problem.
-+
-+
+Fixed bug in depth-of-field blur where view distance was measured from
-+
+fore clipping plane rather than viewpoint.  Thanks to Peter A-B for
-+
+pointing this out.
-+
-+
+Added options to dctimestep to allow multiple time steps (-n)
-+
+and multiple output pictures or sensor files (-o).  Also added -i
-+
+option to specify float (-if) or double (-id) input for sky matrix.
-+
-+
+Created gendaymtx program to compute annual sky patch matrix based
-+
+on Ian Ashdown's implementation of Perez all-weather sky model.
-+
+Output can be sent directly to dctimestep in ASCII or binary stream.
-+
-+
+Replaced existing gendaylit.c with improved version from Wendelin Sprenger
-+
+and Jan Wienold of ISE.
-+
-+
+Improved accuracy of ambient calculation for large -ad settings.  Thanks
-+
+to Lars Grobe for noticing the problem.
-+
-+
+Added -r option to gendaymtx to rotate the sky the specified number of
-+
+degrees about the zenith as suggested by A. McNeil.
-+
-+
+Axel Jacobs added -pal eco color map that does a blue-red-yellow scale.
-+
-+
+Created bsdf2klems tool to convert from various BSDF representations to
-+
+Klems basis matrix in XML file.
-+
-+
+Fixed problem with inappropriate reciprocity enforcement on tensor
-+
+tree reduction in genBSDF.  (Thanks to A.McNeil for discovering issue.)
-+
-+
+Fixed bug in isotropic tensor tree sampling for impinging rays
-+
+exactly normal to surface.  Thanks to Peter Apian-Bennewitz for
-+
+discovering and pointing out the error.
-+
-+
+Fixed double-counting bug in mirror material with alternate type.
-+
+Thanks to David Geisler-Moroder for spotting the problem and helping
-+
+to fix it.
-+
-+
+Created rcollate program to resize and transpose matrix data for Andy
-+
+McNeil's 5-phase annual simulation method.
-+
-+
+Added epw2wea conversion program by Christoph Reinhart.
-+
-+
+Implemented Perlin's improved noise function with help from Rahul Narain.
-+
+This will change the appearance of renderings using this function.
-+
-+
+Added "origin" command to rvu as requested by John Mardaljevic
-+
+to place view origin at selected point in scene.
-+
-+
+Switch to Perl versions of objview and objpict written by Axel Jacobs.
-+
-+
+Improved rendering speed of scenes with aliases by not entering new
-+
+modifiers into table if they are the same as the previously defined
-+
+modifier for that name.
