| 1875 | > |  | 
| 1876 | > | Added -r option to gendaymtx to rotate the sky the specified number of | 
| 1877 | > | degrees about the zenith as suggested by A. McNeil. | 
| 1878 | > |  |

| 1894 | > |  | 
| 1895 | > | Created rcollate program to resize and transpose matrix data for Andy | 
| 1896 | > | McNeil's 5-phase annual simulation method. | 
| 1897 | > |  | 
| 1898 | > | Added epw2wea conversion program by Christoph Reinhart. | 
| 1899 | > |  | 
| 1900 | > | Implemented Perlin's improved noise function with help from Rahul Narain. | 
| 1901 | > | This will change the appearance of renderings using this function. | 
| 1902 | > |  | 
| 1903 | > | Added "origin" command to rvu as requested by John Mardaljevic | 
| 1904 | > | to place view origin at selected point in scene. | 
| 1905 | > |  |

| 1908 | > | Improved rendering speed of scenes with aliases by not entering new | 
| 1909 | > | modifiers into table if they are the same as the previously defined | 
| 1910 | > | modifier for that name. | 
| 1911 | > |  | 
| 1912 | > | Made it so icalc and rcalc search RAYPATH directories for *.cal files | 
| 1913 | > | given on command line.  This simplifies script writing and makes these | 
| 1914 | > | utilities consistent with other tools in Radiance. | 
| 1915 | > |  | 
| 1916 | > | Added triangulation routine to handle convex polygons in obj2mesh. | 
| 1917 | > |  | 
| 1918 | > | ****** COMPATIBILITY CHANGE ******** | 
| 1919 | > | Made backface visibility apply to all material types, including | 
| 1920 | > | transparent and translucent materials (except dielectric and interface). | 
| 1921 | > | This makes the option useful in cases where adjacent trans surfaces | 
| 1922 | > | are placed next to each other by a modeler that only understands | 
| 1923 | > | volumetric objects. | 
| 1924 | > |  | 
| 1925 | > | Changed dctimestep so that output matrices (-n > 1) are preceded by a | 
| 1926 | > | header, and added support for float and double output formats with -o[fd]. | 
| 1927 | > |  | 
| 1928 | > | Introduced eplus_adduvf program to compute user view factors for EnergyPlus. | 
| 1929 | > |  | 
| 1930 | > | Changed image-plane sampling in rpict to use Hilbert curve, which gives | 
| 1931 | > | less of a brushed/striped appearance to output pixels with -u- (default). | 
| 1932 | > |  | 
| 1933 | > | Added ltview and ltpict Perl scripts contributed by Axel Jacobs, inspired | 
| 1934 | > | by Rob Guglielmetti. | 
| 1935 | > |  | 
| 1936 | > | Added header variables for NROWS, NCOLS and NCOMP to help standardize | 
| 1937 | > | matrix files.  This functionality has been incorporated into | 
| 1938 | > | rcollate, gendaymtx, and dctimestep. | 
| 1939 | > |  | 
| 1940 | > | Created rmtxop utility to operate on multi-component matrices.  This | 
| 1941 | > | facilitates some daylight matrix calculations, and provides a general | 
| 1942 | > | tool for manipulating matrix data. | 
| 1943 | > |  | 
| 1944 | > | ****** COMPATIBILITY CHANGE ******** | 
| 1945 | > | Introduced new Hessian-based error control in irradiance caching (ambient) | 
| 1946 | > | calculation.  Since the format of the stored ambient values is different, | 
| 1947 | > | the old files will be rejected with an error message and must be removed. | 
| 1948 | > | The programs may be compiled with the -DOLDAMB option if this is a problem. | 
| 1949 | > |  | 
| 1950 | > | Added -p option to rcontrib to set function file parameters on a per-modifier | 
| 1951 | > | basis to simplify bin evaluation. | 
| 1952 | > |  | 
| 1953 | > | Created rfluxmtx program to compute flux transfer matrices from a sender | 
| 1954 | > | surface to one or more receiver surfaces.  (Renamed the file klems_int.cal | 
| 1955 | > | to klems_full.cal in the process.) | 
| 1956 | > |  | 
| 1957 | > | Added "-c" option to getinfo to execute command on data segment. | 
| 1958 | > |  | 
| 1959 | > | ================================ | 
| 1960 | > | Version 5.0 (Released 9/18/2015) | 
| 1961 | > |  | 
| 1962 | > | Changed rmtxop so it writes out same type as lesser of inputs unless | 
| 1963 | > | directed otherwise using -f? option. | 
| 1964 | > |  | 
| 1965 | > | Changed order of oconv arguments in rfluxmtx so user can specify input | 
| 1966 | > | octree using -i option at the end instead of (or in addition to) a | 
| 1967 | > | list of scene files. | 
| 1968 | > |  | 
| 1969 | > | Added support for argument expansion to rfluxmtx and bug fixes. | 
| 1970 | > |  | 
| 1971 | > | Fixed bug in indirect hemisphere sampling for some corner cases. | 
| 1972 | > |  | 
| 1973 | > | Added default specular lobe to BSDF interpolation. |

| 1978 | > |  | 
| 1979 | > | ****** COMPATIBILITY CHANGE ******** | 
| 1980 | > | Made header input and output the default behavior for dctimestep and | 
| 1981 | > | genskyvec. | 
| 1982 | > |  | 
| 1983 | > | ****** COMPATIBILITY CHANGE ******** | 
| 1984 | > | Changed pabopto2bsdf default behavior to add 90-degree rotation | 
| 1985 | > | to bring pgII's definition of "up" in line with Klems axis | 
| 1986 | > | conventions.  Introduced a new header variable "upphi" to | 
| 1987 | > | control this added rotation.  Using "#upphi 90" in each | 
| 1988 | > | BSDF input file gets back the original behavior, where it | 
| 1989 | > | assumes that the up direction is 90-degrees from the X-axis. | 
| 1990 | > | The default value of 0 corresponds to PAB's definition of | 
| 1991 | > | the X-axis as being "up". | 
| 1992 | > |  | 
| 1993 | > | Fixed bug in rsensor related to having many rows (altitude) and | 
| 1994 | > | few columns (azimuth) in sensitivity file. | 
| 1995 | > |  | 
| 1996 | > | Fixed floating point round-off error in new Hessian calculation | 
| 1997 | > | for some sytems (Windows, primarily). | 
| 1998 | > |  | 
| 1999 | > | Fixed bug in tensor tree BSDF code that caused bus error on | 
| 2000 | > | some systems, and may have been source of other errors as well. | 
| 2001 | > |  | 
| 2002 | > | (Above changes included in 4.2.2 patch release.) | 
| 2003 | > |  | 
| 2004 | > | Improved ambient extrapolation to avoid zero values.  Actual | 
| 2005 | > | threshold set to 5% of recorded value. | 
| 2006 | > |  | 
| 2007 | > | Changed anisotropic Gaussian and Ashikhmin models so that | 
| 2008 | > | illegal orientation vectors are dealt with more gracefully. | 
| 2009 | > |  | 
| 2010 | > | Created wrapBSDF tool and incorporated into genBSDF along | 
| 2011 | > | with new rfluxmtx computation. | 
| 2012 | > |  | 
| 2013 | > | Initial check-in of Roland Schregle's photon map integration. | 
| 2014 | > | New 5.0a version designation as suggested by Andy McNeil. | 
| 2015 | > |  | 
| 2016 | > | Added left-hand coordinate sytems to rfluxmtx to correct | 
| 2017 | > | problems with coordinate axis orientations pointed out by | 
| 2018 | > | David Geisler-Moroder. | 
| 2019 | > |  | 
| 2020 | > | Added color output to genBSDF (+C option) and support for | 
| 2021 | > | color rendering of Klems and tensor tree data. | 
| 2022 | > |  | 
| 2023 | > | Fixed another bug in rsensor that caused rays to be generated | 
| 2024 | > | on opposite side of hemisphere even where sensitivity was zero. |

| 2026 | > | Fixed bug discovered by Jacob Jonsson in Klems BSDF | 
| 2027 | > | interpolator that caused it to over-predict normal | 
| 2028 | > | transmittance and reflectance. | 
| 2029 | > |  | 
| 2030 | > | Added ability to read input from commands in dctimestep | 
| 2031 | > | and rmtxop. | 
| 2032 | > |  | 
| 2033 | > | Added photon map support to rad.  Fixed some double-counting | 
| 2034 | > | issues in photon-mapping spotted by David Geisler-Moroder. | 
| 2035 | > |  | 
| 2036 | > | Added photon map support to trad. | 
| 2037 | > |  | 
| 2038 | > | Fixed bug in antimatter source testing when antimatter | 
| 2039 | > | definition follows potential obstructor in input. | 
| 2040 | > |  | 
| 2041 | > | Fixed issue with missing character type identifier at head | 
| 2042 | > | of genBSDF XML output. | 
| 2043 | > |  | 
| 2044 | > | Prompted by Roland S., added option to have pcompos -a order | 
| 2045 | > | rows from top rather than bottom of image. | 
| 2046 | > |  | 
| 2047 | > | Changed dctimestep to accept matrix as well as BTDF input | 
| 2048 | > | in the VTDs invocation mode.  This permits the output of | 
| 2049 | > | rmtxop to be used in a pinch when combining multiple BTDF | 
| 2050 | > | layers, although interreflection between layers is not | 
| 2051 | > | accounted for properly as it is in the WINDOW program. | 
| 2052 | > |  | 
| 2053 | > | Added Jan Wienold et al.'s evalglare to distribution. | 
| 2054 | > |  | 
| 2055 | > | Hopeful fix to deadlock issue under Mac OS X 10.10.x (Yosemite). |

| 2072 | > | to enable on input. | 
| 2073 | > |  | 
| 2074 | > | Rewrote bsdf2klems to support tristimulus color and call wrapBSDF. | 
| 2075 | > | Did the same for bsdf2ttree.  Function specifications still gray only. | 
| 2076 | > |  | 
| 2077 | > | Reduced a problem where rvu or rholo would be slow to quit when | 
| 2078 | > | run with many processes on a large model or one with a large | 
| 2079 | > | ambient file (taking lots of memory).  We were waiting for | 
| 2080 | > | processes to quit one-by-one, which takes some time for each | 
| 2081 | > | process as it disentangles its shared memory.  We now | 
| 2082 | > | wait for all the processes together, so they can disentangle |

| 2084 | > | but not 10 minutes like it was taking before the fix. | 
| 2085 | > |  | 
| 2086 | > | Enabled ambient cache value corral for all levels, not just final two. | 
| 2087 | > | This may reduce errors in certain pathological scenes. | 
| 2088 | > |  | 
| 2089 | > | Added -in option to rcalc, rlam, and total to limit the number of | 
| 2090 | > | input records in hopes of circumventing Windows EOF issues on binary data. | 
| 2091 | > | Also added -on option to rcalc and total for logical symmetry. | 
| 2092 | > |  | 
| 2093 | > | Increased modifier limit to 10,000 in rcontrib. | 
| 2094 | > |  | 
| 2095 | > | Fixed issues with glrad and added zoom response to mouse wheel input. | 
| 2096 | > |  | 
| 2097 | > | Added missing definition of "ashik2" material type to reference manual. | 
| 2098 | > |  | 
| 2099 | > | Changed genBSDF to calculate device thickness assuming Zmax==0 so | 
| 2100 | > | pkgBSDF will generate correct proxy geometry. | 
| 2101 | > |  | 
| 2102 | > | Created pabopto2xyz tool to combine different sensor measurements | 
| 2103 | > | into a single CIE-XYZ measurement file for color BSDF interpolation. |

| 2105 | > | Jan Wienold updated evalglare to version 1.30 | 
| 2106 | > |  | 
| 2107 | > | Roland Schregle added out-of-core photon mapping routines, which |

| 2109 | > |  | 
| 2110 | > | Added -a option to getinfo for easy addition of header lines. | 
| 2111 | > |  | 
| 2112 | > | Fixed issue with multiple records on picture output in rcontrib (and rfluxmtx). |

| 2118 | > |  | 
| 2119 | > | Fixed genBSDF issue that was created incorrect normalization of | 
| 2120 | > | Klems output.  Thanks to David G-M and Christian Knoflach for | 
| 2121 | > | discovering the error.  Also improved sampling of indirect irradiance | 
| 2122 | > | that showed some slight bias due to poor sample collision avoidance. | 
| 2123 | > |  | 
| 2124 | > | Fixed long-standing issue with -aa 0 neglecting textures in calculating | 
| 2125 | > | surface shading. |

| 2128 | > |  | 
| 2129 | > | Added check for steep sections of BSDF in pabopto2bsdf, creating narrower |

| 2239 | > | ========================= | 
| 2240 | > | Version 5.3 (Released September 1, 2020) | 
| 2241 | > |  | 
| 2242 | > | Created radcompare program to compare Radiance tool output to reference outputs | 
| 2243 | > | during unit-testing. | 
| 2244 | > |  | 
| 2245 | > | Fixed issue reading very large files (> 2 GBytes) in rcollate. | 
| 2246 | > |  | 
| 2247 | > | Made picking function in rvu ignore transparent and void surfaces. | 
| 2248 | > |  | 
| 2249 | > | Added -orRxX options to rtrace to enable output of mirrored and unmirrored | 
| 2250 | > | contributions and distances to enable new types of reprojections.  This also | 
| 2251 | > | cleaned up and unified handling of effective ray lengths throughout code. | 
| 2252 | > |  | 
| 2253 | > | Bug fixes from Jan Wienold for evalglare. | 
| 2254 | > |  | 
| 2255 | > | Changed indexed (numbered) output from dctimestep to start from 0 rather | 
| 2256 | > | than 1, to make it more consistent with expected input naming. | 
| 2257 | > |  | 
| 2258 | > | Increased default sampling in bsdf2klems (-n option) to 1024. | 
| 2259 | > |  | 
| 2260 | > | Fixed an issue noticed by David G-M that was causing genBSDF to bias | 
| 2261 | > | isotropic tensor tree samples resulting in subsequent failure of | 
| 2262 | > | peak extraction with "aBSDF" type. | 
| 2263 | > |  | 
| 2264 | > | Introduced max() and min() functions to .cal library. | 
| 2265 | > |  | 
| 2266 | > | Added random incident patch sampling to bsdf2klems to improve accuracy | 
| 2267 | > | with scattering interpolation representation input (e.g., from | 
| 2268 | > | pabopto2bsdf).  The other input types already sampled incident patch area. | 
| 2269 | > |  | 
| 2270 | > | Added gendaymtx -A option to compute average sky over all the input | 
| 2271 | > | time steps. | 
| 2272 | > |  | 
| 2273 | > | Added ability to output color image from rtrace with any of -ovrx options. | 
| 2274 | > | Also fixed inconsistency of -oN output when ray casting versus full trace. | 
| 2275 | > | Before, it would flip normal to front side unless ray casting.  Now, -oN | 
| 2276 | > | always reports the unflipped normal. | 
| 2277 | > |  | 
| 2278 | > | Changed rlam behavior so -iaN reads N lines from a stream rather than N | 
| 2279 | > | characters.  This seems more useful, since -ibN is somewhat redundant with | 
| 2280 | > | the old behavior. | 
| 2281 | > |  | 
| 2282 | > | Created rsplit program as compliment to rlam and to handle more complex | 
| 2283 | > | rtrace output into separate files or streams. | 
| 2284 | > |  | 
| 2285 | > | Improved getinfo so that it can also hop over resolution string with -c | 
| 2286 | > | and header elide mode.  Use +d to include resolution string in output, | 
| 2287 | > | and -d to elide with - and -c options. | 
| 2288 | > |  | 
| 2289 | > | Made pvalue -u option mean "uncompressed" with -r.  Also, allow skipping | 
| 2290 | > | bytes on standard input. | 
| 2291 | > |  | 
| 2292 | > | Created rcode_depth tool to convert to and from a 16-bit/pixel portable | 
| 2293 | > | depth image encoding that uses a mix of linear and reciprocal distance | 
| 2294 | > | with explicit representations of 0 and infinity.  Code for loading these | 
| 2295 | > | depth maps is in src/common/depthcodec.{h,c}. | 
| 2296 | > |  | 
| 2297 | > | Created rcode_norm tool to convert to and from 32-bit/pixel portable | 
| 2298 | > | surface normal representation, matching the one in src/common/dircode.c. | 
| 2299 | > | Code for loading normal maps is in src/common/normcodec.{h,c}. | 
| 2300 | > |  | 
| 2301 | > | Created rcode_ident tool to create indexed identifier files. | 
| 2302 | > | Code for loading these files is in src/common/idmap.{h,c}. | 
| 2303 | > |  | 
| 2304 | > | Added -o* option to rtpict to produce layered images that handle most | 
| 2305 | > | output types from rtrace (colors, surface normals, distances, IDs). | 
| 2306 | > |  | 
| 2307 | > | Created rcode2bmp script to create images from new rcode_* output maps. | 
| 2308 | > |  | 
| 2309 | > | Improved efficiency of rmtxop in cases where matrix multiplication is | 
| 2310 | > | faster evaluated right-to-left, as when the final component is a | 
| 2311 | > | column vector.  Also added ability to apply trailing unary operators | 
| 2312 | > | (-t, and -s or -c) to resulting matrix. | 
| 2313 | > |  | 
| 2314 | > | Added new depth, normal, and ID file types to radcompare. | 
| 2315 | > |  | 
| 2316 | > | Added BigEndian= header line for automatic byte-swapping in rmtxop | 
| 2317 | > | and radcompare. | 
| 2318 | > |  | 
| 2319 | > | Added new "turbo" palette to falsecolor (thanks to Taoning). | 
| 2320 | > |  | 
| 2321 | > | Nathaniel Jones created the "dcglare" program for annual glare | 
| 2322 | > | simulations when the sun and sky are visible through the window. | 
| 2323 | > | Tutorial is posted at | 
| 2324 | > | "https://github.com/nljones/Accelerad/wiki/The-Imageless-Method-for-Spatial-and-Annual-Glare-Analysis". | 
| 2325 | > |  | 
| 2326 | > | Added support for loading RGBE images into matrices in dctimestep. | 
| 2327 | > |  | 
| 2328 | > | Added -y option to gensky and gendaylit to support more accurate Michalsky | 
| 2329 | > | solar position calculation. | 
| 2330 | > |  | 
| 2331 | > | Changed rsplit, so specifying a space as the separator parses words | 
| 2332 | > | between whitespace. | 
| 2333 | > |  | 
| 2334 | > | Added ability of vwrays, pinterp, and pmblur2 to read encoded depth files. | 
| 2335 | > |  | 
| 2336 | > | Added -o RxCxR1xC1 facility to perform blocking in rcollate. | 
| 2337 | > |  | 
| 2338 | > | Made it so number of segments in genworm, genrev, and gensurf can be | 
| 2339 | > | given as expressions of previously defined variables, etc. | 
| 2340 | > |  | 
| 2341 | > | Added -D and -n option to gendaymtx to output sun description and skip | 
| 2342 | > | matrix output on request.  A -M option was also added to output solar | 
| 2343 | > | modifiers for rcontrib.  Support also added for leap days in WEA input. | 
| 2344 | > | Enhancements sponsored by Ladybug Tools. | 
| 2345 | > |  | 
| 2346 | > | Updated eplus_uvf to work with IDF version 9.x, checking version number. | 
| 2347 | > |  | 
| 2348 | > | Fix to glarendx issues with dgi calculation. | 
| 2349 | > |  | 
| 2350 | > | Made it so rmtxop and dctimestep undo any exposure applied to Radiance | 
| 2351 | > | pictures they may load. | 
| 2352 | > |  | 
| 2353 | > | Added robjutil utility to manipulate Wavefront .OBJ files. | 
| 2354 | > |  | 
| 2355 | > | Fixed a crash related to rtrace -om or -oM with mesh instances containing | 
| 2356 | > | materials. | 
| 2357 | > |  | 
| 2358 | > | Improved rtrace flushing function to handle any value for -x without | 
| 2359 | > | deadlock on controlling process. | 
| 2360 | > |  | 
| 2361 | > | Eliminated unnecessary start-up procedures for rtrace when only ray-casting | 
| 2362 | > | is needed (i.e., no tracing or value output). | 
| 2363 | > |  | 
| 2364 | > | Improved isotropic sampling method in bsdf2ttree using "zipper" approach | 
| 2365 | > | applied in genBSDF. | 
| 2366 | > |  | 
| 2367 | > | Added limit to memory used by high-resolution tensor tree BSDFs for | 
| 2368 | > | cumulative cache during MC sampling (rendering).  Limit set to 250MBytes | 
| 2369 | > | per BSDF for standard architectures. | 
| 2370 | > |  | 
| 2371 | > | Added -n and -s options to bsdf2ttree to provide some user control | 
| 2372 | > | over super-sampling. | 
| 2373 | > |  | 
| 2374 | > | Improved surface normal codec used by ambient file to store orthonormal | 
| 2375 | > | directions exactly. | 
| 2376 | > |  | 
| 2377 | > | Improved peak extraction method, which was undervaluing transmission | 
| 2378 | > | in many cases. | 
| 2379 | > |  | 
| 2380 | > | New version of evalglare from Jan Wienold. | 
| 2381 | > |  | 
| 2382 | > | Added -u option to gendaymtx to elide data columns (time steps) when | 
| 2383 | > | the sun is not visible above the horizon. | 
| 2384 | > |  | 
| 2385 | > | ========================= | 
| 2386 | > | Version 5.4 | 
| 2387 | > |  | 
| 2388 | > | Added rcollate -c option to force operation to continue even if it | 
| 2389 | > | seems unnecessary.  Made tool more robust. | 
| 2390 | > |  | 
| 2391 | > | Added -t option to rcontrib (and rfluxmtx) to report progress after the | 
| 2392 | > | given number of seconds. | 
| 2393 | > |  | 
| 2394 | > | Added "test" target to makeall to run unit tests. | 
| 2395 | > |  | 
| 2396 | > | Modified bsdf2ttree to allow different parameters per input SIR file. | 
| 2397 | > |  | 
| 2398 | > | Fixed issues with very large matrix files (> 2GB) in dctimestep, rmtxop, | 
| 2399 | > | and rcollate. | 
| 2400 | > |  | 
| 2401 | > | Added -rf and -rb options to rmtxop to load front or back reflectance | 
| 2402 | > | matrix data from XML file rather than transmission.  (Lars Grobe suggested.) | 
| 2403 | > |  | 
| 2404 | > | Improved behavior for coincident surfaces with different materials. | 
| 2405 | > | Rather than returning one surface or the other based on floating-point | 
| 2406 | > | vagaries, opaque materials are now preferred over transparent ones. | 
| 2407 | > | If the materials are both transparent or both opaque, then whichever | 
| 2408 | > | surface appeared later in the scene description will be selected. | 
| 2409 | > | This came of a request for consistent behavior with legal CAD output | 
| 2410 | > | from Peter Apian-Bennewitz. | 
| 2411 | > |  | 
| 2412 | > | Added explicit tests for on-edge intersections with polygons.  This should | 
| 2413 | > | eliminate stray rays and tiny light leaks that often appear even in | 
| 2414 | > | well-constructed geometry. | 
| 2415 | > |  | 
| 2416 | > | Added "-s up" option to pabopto2bsdf to allow for 180 degree symmetry, | 
| 2417 | > | meaning that data repeats after 180 degree rotation (as distinguished | 
| 2418 | > | from "-s bilateral" whose data is mirrored about a vertical plane). | 
| 2419 | > | Thanks to Helen Rose Wilson for the suggestion and informing me that | 
| 2420 | > | such a thing exists. | 
| 2421 | > |  | 
| 2422 | > | Removed upper limit on number of modifiers in rcontrib. | 
| 2423 | > |  | 
| 2424 | > | Put cap on maximum ambient gradient to avoid over-extrapolation of | 
| 2425 | > | poorly computed irradiance cache values. | 
| 2426 | > |  | 
| 2427 | > | Added robjutil +T option to triangulate all faces in .OBJ description. | 
| 2428 | > |  | 
| 2429 | > | Altered BSDF library to have both front and back diffuse transmittance | 
| 2430 | > | values, which can be different.  This was necessary to avoid issues | 
| 2431 | > | caused by measurement and modeling discrepancies. | 
| 2432 | > |  | 
| 2433 | > | Added pabopto2bsdf -g option to cull near-grazing scattering to avoid | 
| 2434 | > | issues with noise and negative values. | 
| 2435 | > |  | 
| 2436 | > | Increased default dynamic range from 32 to 100 in pcond and normtiff. | 
| 2437 | > |  | 
| 2438 | > | Added -o and -n options to genbox to create .OBJ output and segment | 
| 2439 | > | edges and corners for transparent materials. |
