Added -N option to objview to support multiprocessing. + +Improved sampling of circular sources (source, sphere, ring types) with +quite a bit of help from David Geisler-Moroder. + +Added "rpict" and "rvu" variables to rad, and made these as well as +the "oconv", "mkillum" and "pfilt" variables accept an alternate +command path in each case. Change suggested by Lars Grobe based +on similar Radzilla (radz) facility by Carsten Bauer. + +Fixed rad -v N specification to use actual view name if one. + +Fixed error in mkillum calculation where it neglected indirect +source contributions from BTDF illum's. + +Added GMT and LATLONG header lines for Greenwich Mean Time and +degrees North Latitude / East Longitude. + +Added gendaylit to distribution (finally). + +Added ability in vwright(1) to get view from command line arguments. + +Created genklemsamp(1) utility to generate samples suitable for +BSDF-based annual calculations. This is the first Perl script to +be added to Radiance. Hopefully, others will follow. + +Added klems_int.cal file to compute Klems bins for windows. + +Created genskyvec utility to sample a particular sky and +evaluate average radiance over the standard Tregenza sky patches. + +Created dctimestep program to compute a set of sensor values or +a combined image for a particular time using the daylight +coefficient method. + +Created src/rt/rayfifo.c for first-in/first-out handling of +multiprocessing by raypcalls.c. + +Added -n option to rtrace for executing on multiple cores +using new rayfifo calls. + +===================== +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 +home directory. + +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 (Release date 7/31/2014) + +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. + +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.
