| 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. | 
| 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.  Doesn't work quite as automatically as it should | 
| 2318 | < | for pvalue -r, currently. | 
| 2317 | > | and radcompare. | 
| 2318 |  |  | 
| 2319 |  | Added new "turbo" palette to falsecolor (thanks to Taoning). | 
| 2320 |  |  | 
| 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 | 
| 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. | 
| 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. | 
| 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 |  |  | 
| 2350 |  | Made it so rmtxop and dctimestep undo any exposure applied to Radiance | 
| 2351 |  | pictures they may load. | 
| 2352 |  |  | 
| 2353 | < | Added objutil utility to manipulate Wavefront .OBJ files. | 
| 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. |

| 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. |
