Version 5.3 (Released September 1, 2020) |
| 2241 |
|
|
| 2242 |
|
Created radcompare program to compare Radiance tool output to reference outputs |
| 2243 |
|
during unit-testing. |
| 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 |
| 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 |

|
| 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 |

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. Also added -s option |
| 2440 |
> |
to control smoothing for .OBJ and Radiance with segmented rounding. |
| 2441 |
> |
|
| 2442 |
> |
Made it so robjutil with the +r option for Radiance output now |
| 2443 |
> |
produces normal smoothing unless normals are removed with -n. |
| 2444 |
> |
|
| 2445 |
> |
Added exposure preservation to pcompos when possible (i.e., when |
| 2446 |
> |
there is only one input or inputs agree on exposure). |
| 2447 |
> |
|
| 2448 |
> |
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. |
| 2453 |
> |
|
| 2454 |
> |
Added automatic flushing to the output of total, except when the -r |
| 2455 |
> |
(running subtotals) option is used. |
| 2456 |
> |
|
| 2457 |
> |
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 |
> |
|
| 2486 |
> |
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. |
| 2490 |
> |
Unfortunately, this code is not tested, since I don't have any IES |
| 2491 |
> |
files that use these shapes. |
| 2492 |
> |
|
| 2493 |
> |
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. |
