# Line 2157 | Line 2157 | Added bsdfview tool analogous to objview but for BSDF
2157   which calls bsdf2rad then rad with a few useful default views.
2158  
2159   =========================
2160 < Version 5.2
2160 > Version 5.2 (Release October 8, 2018)
2161  
2162   Created psketch program to apply non-photorealistic rendering to selected
2163   objects, identified by modifier name(s).
# Line 2211 | Line 2211 | Thanks to Lars Grobe for pointing out issues.
2211   Added RAYPATH searching for -f options to genrev, gensurf, genworm,
2212   bsdf2klems, bsdf2ttree, and pcomb.  This makes behavior consistent
2213   with rcalc, calc, and rendering tools.
2214 +
2215 + Worked with Randolph Fritz to fix some issues with ies2rad and newer
2216 + IESNA63 standards.
2217 +
2218 + Resurrected original bsdf2rad test program, renaming it bsdf2rado. Still an
2219 + optional build in src/cv/.
2220 +
2221 + Fixed bug in rcontrib with virtual sources, where pretest was adding
2222 + to modifier accumulation buffers.  Reported by Mostapha.
2223 +
2224 + Added an "aBSDF" material type that explicitly checks for peak extraction.
2225 + Its arguments are the same as the original "BSDF" type, but without the
2226 + thickness parameter, as proxy geometry is not supported by this new type.
2227 + The old "BSDF" type no longer does peak extraction under any circumstances,
2228 + since this behavior is superfluous for proxied geometry.
2229 +
2230 + Added -r option to bsdf2rad (and bsdfview) to fix BSDF min and max range
2231 + for comparing BSDFs.
2232 +
2233 + Fixed issue with pfilt -m option and uneven image size changes pointed
2234 + out by Rob Shakespeare.
2235 +
2236 + Updates to evalglare and gendaylit from Jan Wienold, including new
2237 + colored sky option.
2238 +
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.
