+driver for rvu, which is built in the new subdirectory src/qtrvu.
+=====================
-<
+Version 4.2
->
+Version 4.2 (Release date 7/31/2014)
+Axel Jacobs added -cp and -palettes options to falsecolor.
+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.
-+
-+
+Made it so icalc and rcalc search RAYPATH directories for *.cal files
-+
+given on command line.  This simplifies script writing and makes these
-+
+utilities consistent with other tools in Radiance.
-+
-+
+Added triangulation routine to handle convex polygons in obj2mesh.
-+
-+
+****** COMPATIBILITY CHANGE ********
-+
+Made backface visibility apply to all material types, including
-+
+transparent and translucent materials (except dielectric and interface).
-+
+This makes the option useful in cases where adjacent trans surfaces
-+
+are placed next to each other by a modeler that only understands
-+
+volumetric objects.
-+
-+
+Changed dctimestep so that output matrices (-n > 1) are preceded by a
-+
+header, and added support for float and double output formats with -o[fd].
-+
-+
+Introduced eplus_adduvf program to compute user view factors for EnergyPlus.
-+
-+
+Changed image-plane sampling in rpict to use Hilbert curve, which gives
-+
+less of a brushed/striped appearance to output pixels with -u- (default).
-+
-+
+Added ltview and ltpict Perl scripts contributed by Axel Jacobs, inspired
-+
+by Rob Guglielmetti.
-+
-+
+Added header variables for NROWS, NCOLS and NCOMP to help standardize
-+
+matrix files.  This functionality has been incorporated into
-+
+rcollate, gendaymtx, and dctimestep.
-+
-+
+Created rmtxop utility to operate on multi-component matrices.  This
-+
+facilitates some daylight matrix calculations, and provides a general
-+
+tool for manipulating matrix data.
-+
-+
+****** COMPATIBILITY CHANGE ********
-+
+Introduced new Hessian-based error control in irradiance caching (ambient)
-+
+calculation.  Since the format of the stored ambient values is different,
-+
+the old files will be rejected with an error message and must be removed.
-+
+The programs may be compiled with the -DOLDAMB option if this is a problem.
-+
-+
+Added -p option to rcontrib to set function file parameters on a per-modifier
-+
+basis to simplify bin evaluation.
-+
-+
+Created rfluxmtx program to compute flux transfer matrices from a sender
-+
+surface to one or more receiver surfaces.  (Renamed the file klems_int.cal
-+
+to klems_full.cal in the process.)
-+
-+
+Added "-c" option to getinfo to execute command on data segment.
-+
-+
+=====================
-+
+Version 4.3
-+
-+
+Changed rmtxop so it writes out same type as lesser of inputs unless
-+
+direction 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
-+
+list of scene files.
-+
-+
+Added support for argument expansion to rfluxmtx and bug fixes.
-+
-+
+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.)
-+
-+
+===================
-+
+Version 5.0
-+
-+
+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.
