# Line 2237 | Line 2237 | Updates to evalglare and gendaylit from Jan Wienold, i
2237   colored sky option.

2239   =========================
2240 < Version 5.3
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.
# Line 2271 | Line 2271 | Added gendaymtx -A option to compute average sky over
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
# Line 2280 | Line 2283 | Created rsplit program as compliment to rlam and to ha
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.
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.
