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. + +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.) + +Improved ambient extrapolation to avoid zero values. Actual +threshold set to 5% of recorded value.
