Version 5.1 (Released 8/17/2017) | 
| 2062 | 
  | 
 | 
| 2063 | 
  | 
Fixed issue with vchars.mta and symbols.mta not being installed in | 
| 2064 | 
  | 
the appropriate metafile library location, with help from Rob G. | 
| 2146 | 
  | 
Added ability to perform shadow-testing through unproxied BSDFs with strong | 
| 2147 | 
  | 
through (direct-direct) component. | 
| 2148 | 
  | 
 | 
| 2149 |

Added bias to see through BTDFs with a strong "through" component | 
| 2153 |

 | 
| 2156 |

Added bsdfview tool analogous to objview but for BSDF files (XML and SIR), | 
| 2157 |

 | 
| 2175 |

some conditions. | 
| 2178 | 
> | 
 | 
| 2179 | 
> | 
Increased maximum number of open files in rcontrib to the system upper |

limit of 2048 rather than the default 512 under Windows. | 
| 2181 | 
> | 
 |

Improved accuracy for peaky BSDFs and small light sources. | 
| 2185 |

Fixed issue with pmapdump noted by Axel Jacobs. | 
| 2187 | 
> | 
 | 
| 2188 |

Improved accuracy of bsdf2ttree when converting scattering interpolation | 
| 2189 |

representatons with strong peaks. | 
| 2190 | 
> | 
 | 
| 2191 |

Tweaked peak-extraction code to work more reliably. | 
| 2192 |

Georg Mischler updated SCons build system. | 
| 2194 |

| 2195 | 
> | 
Rob Guglielmetti and Alex Swindler updated CMake build system. | 
| 2196 |

 | 
| 2197 | 
> | 
Modified pcomb so the first view seen in the inputs is written into header. | 
| 2198 | 
> | 
 | 
| 2199 | 
> | 
Wrote rtpict script to run rtrace in parallel mode and simulate rpict with | 
| 2200 |

-n option. | 
| 2201 | 
> | 
 | 
| 2202 | 
> | 
Added ability to move forwards/backwards specified distance in rvu "origin" | 
| 2203 |

command.  Feature requested by John Mardaljevic, who essentially owns this | 
| 2204 | 
> | 
command, now. | 
| 2205 |

 | 
| 2206 |

Reduced bias in ambient super-sampling method. | 
| 2207 | 
> | 
 | 
| 2208 |

Fixed bugs associated with zero transmission in chromatic tensor trees. | 
| 2209 |

Thanks to Lars Grobe for pointing out issues. | 
| 2210 |

 | 
| 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 |

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. |

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 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 |

 | 
| 2353 |

Added robjutil utility to manipulate Wavefront .OBJ files. | 
| 2354 | 
> | 
 | 
| 2355 | 
> | 
Fixed a crash related to rtrace -om or -oM with mesh instances containing |

> | 
 | 
| 2358 |

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 |

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 |

 | 
| 2396 |

 | 
| 2398 |

Fixed issues with very large matrix files (> 2GB) in dctimestep, rmtxop, | 
| 2399 | 
> | 
and rcollate. | 
| 2400 | 
> | 
 | 
| 2401 |

matrix data from XML file rather than transmission.  (Lars Grobe suggested.) | 
| 2403 |

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 |

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 |

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.  Also added -s option | 
| 2440 |

to control smoothing for .OBJ and Radiance with segmented rounding. |

Made it so robjutil with the +r option for Radiance output now | 
| 2443 |

produces normal smoothing unless normals are removed with -n. | 
| 2444 |

 |

Added exposure preservation to pcompos when possible (i.e., when | 
| 2446 |

there is only one input or inputs agree on exposure). | 
| 2447 |

Added -DSHARP_RGB compile-time option to use sharp RGB color space | 
| 2449 | 
> | 
rather than historic default.  This can make for more accurate color | 
| 2450 |

calculations, but requires that materials be recalibrated.  The | 
| 2451 |

PRIMARIES= line is also produced on output from rpict or rvu with | 
| 2452 |

the correct set of primaries based on how the system was compiled. |

Added automatic flushing to the output of total, except when the -r | 
| 2455 |

(running subtotals) option is used. | 
| 2456 |

Improved behavior of little-used -aw option, so that it avoids sea-level | 
| 2458 |

rise caused by adding its own estimate back into the ambient level remainder. | 
| 2459 |

It ended up being simple enough to derate the final average by the factor | 
| 2460 |

corresponding to average surface absorpition, thus removing the average | 
| 2461 |

from the final bounce estimate. |

Introduced ies2rad upgrades by Randolph Fritz.  Randolph says it | 
| 2464 | 
> | 
fixes the following problems: | 
| 2465 | 
> | 
 | 
| 2466 | 
> | 
        1. Generates correct Radiance geometry for spheres in 1995, 2002, | 
| 2467 | 
> | 
        and 2019 IES files. | 
| 2468 | 
> | 
 | 
| 2469 | 
> | 
        2. Generates correct Radiance geometry for vertical cylinders that | 
| 2470 | 
> | 
        are taller than they are wide. | 
| 2471 | 
> | 
 | 
| 2472 | 
> | 
        3. Ignores the file source ("File Generation Type") field in the | 
| 2473 | 
> | 
        2019 version of the file, which would otherwise be incorrectly used | 
| 2474 |

        as an output multiplier. | 
| 2475 |

 | 
| 2476 |

    It also offers the following enhancements: | 
| 2477 | 
> | 
 | 
| 2478 | 
> | 
        1. Shape information is included in the .rad file comments. | 
| 2479 | 
> | 
 | 
| 2480 | 
> | 
        2. 1995, 2002, and 2019-version luminous opening geometry is | 
| 2481 | 
> | 
        accounted for. | 
| 2482 | 
> | 
 | 
| 2483 | 
> | 
        3. The 2002 and 2019 IES file versions are recognized and | 
| 2484 | 
> | 
        processed appropriately. | 
| 2485 |

        4. I have made an attempt to do something intelligent with less | 
| 2487 |

        common "luminous opening" shapes in the 1995, 2002, and 2019 versions | 
| 2488 |

        of the standard, though I have not implemented any support for new | 
| 2489 |

        geometry; approximations are substituted and warning messages issued. |

        Unfortunately, this code is not tested, since I don't have any IES | 
| 2491 |

        files that use these shapes. |

Added support for depth-of-field blurring in vwrays using -pd option. | 
| 2494 | 
> | 
Also, made -c count work with vwrays -i, producing multiple samples | 
| 2495 | 
> | 
per indicated pixel position.  At the same time, support for the -pd | 
| 2496 | 
> | 
option was added to rtpict, which calls on vwrays for its samples. | 
| 2497 | 
> | 
 | 
| 2498 | 
> | 
Fixed issue with BSDFs that didn't obey reciprocity, where direct | 
| 2499 | 
> | 
sampling wasn't following exactly with indirect sampling.  This was | 
| 2500 | 
> | 
discovered and reported by Jon Sargent. | 
| 2501 | 
> | 
 | 
| 2502 | 
> | 
Created checkBSDF tool to test XML BSDF reciprocity and perform similar | 
| 2503 | 
> | 
sanity checks. | 
| 2504 | 
> | 
 | 
| 2505 | 
> | 
Added -O option to pvalue and pextrem to report watts/sr/m^2 even if | 
| 2506 | 
> | 
picture is XYZE. | 
| 2507 | 
> | 
 | 
| 2508 | 
> | 
Made subtle changes to header i/o routines to preserve alignment in | 
| 2509 | 
> | 
binary file formats to enable memory-mapping.  Implemented memory-mapped | 
| 2510 | 
> | 
matrix loading in rmtxop for binary double files. | 
| 2511 | 
> | 
 | 
| 2512 |

Removed ambient value sorting, which was written when ambient caches | 
| 2513 | 
> | 
could overwhelm available memory.  This is rarely the case these days, | 
| 2514 | 
> | 
and the added code complexity and updating of cache values with LRU | 
| 2515 | 
> | 
counts dirties pages that would otherwise remain clean, so it was | 
| 2516 | 
> | 
often a loss even when VM was an issue. | 
| 2517 | 
> | 
 | 
| 2518 | 
> | 
Added iso2klems script to compute a Klems BSDF based on specular | 
| 2519 | 
> | 
and diffuse measurements as a function of incident angle. | 
| 2520 | 
> | 
 | 
| 2521 | 
> | 
Fixed issue with over-counting diffuse component during aBSDF | 
| 2522 | 
> | 
peak extraction. | 
| 2523 | 
> | 
 | 
| 2524 |

Added dctimestep -x and -y options to specify image dimensions | 
| 2525 | 
> | 
for multiple outputs corresponding to result vectors. | 
| 2526 | 
> | 
 | 
| 2527 |

Added -P option to rcalc to pass formatted input when cond is <= 0. | 
| 2528 |

 | 
| 2529 | 
> | 
Created rcrop utility for cropping matrices and pictures more | 
| 2530 | 
> | 
conveniently, correcting view information.  Expect it to be handy | 
| 2531 | 
> | 
for extracting rows and columns from matrices, mostly. | 
| 2532 | 
> | 
 | 
| 2533 | 
> | 
Changed pcomb so -o option elides original exposure values | 
| 2534 | 
> | 
from indented source headers. | 
| 2535 | 
> | 
 | 
| 2536 | 
> | 
Added getinfo -r option, which is similar to -a except it will | 
| 2537 | 
> | 
replace indicated lines with new ones. | 
| 2538 | 
> | 
 | 
| 2539 | 
> | 
Slight change to vwrays -d option to not spit out "-ld-", and to | 
| 2540 | 
> | 
produce "-ld+" without requiring input picture as argument. | 
| 2541 | 
> | 
 | 
| 2542 | 
> | 
Added automatic overture calculation to rtpict with -n > 1 if | 
| 2543 | 
> | 
ambient cache is on and file is named.  If straight image output | 
| 2544 | 
> | 
is requested, we randomize all samples and avoid cache collisions. | 
| 2545 | 
> | 
 | 
| 2546 | 
> | 
Added cnt -s option to shuffle output. |
