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. |

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. |

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 |

|
| 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 |

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 |

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. |
| 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. |
| 2547 |
> |
|
| 2548 |

Fixed issue with divide-by-zero errors in the ambient super-sampling |
| 2549 |
> |
routine discovered by Jon Sargent of Solemma. This affected regions |
| 2550 |
> |
that had zero radiance, such as black backgrounds or unlit areas |
| 2551 |
> |
with -av 0 0 0, when super-sampling was effectively disabled, causing |
| 2552 |
> |
some loss in accuracy of the results. |
| 2553 |

|
| 2554 |

Updated Klems Half- and Quarter-bases to match angles currently used |
| 2555 |
> |
in WINDOW. |
| 2556 |
> |
|
| 2557 |
> |
Eliminated most aiming failures for triangular light sources, at the |
| 2558 |
> |
expense of conservative sampling near the centroid. Thanks to |
| 2559 |
> |
David Geisler-Moroder for his help on this. |
| 2560 |
> |
|
| 2561 |
> |
Increased maximum set size to 8191 to avoid set overflow errors. |
| 2562 |
> |
|
| 2563 |
> |
Added source obstruction test to statistics being kept on which |
| 2564 |
> |
sources were visible in adaptive shadow testing code. Previous |
| 2565 |
> |
behavior was likely over-estimating source contributions. |
| 2566 |
> |
|
| 2567 |
> |
Added diffuse components into maximum directional hemispherical |
| 2568 |
> |
reported by checkBSDF, so comparing to 100% is easier for each |
| 2569 |
> |
component. |
| 2570 |

|
| 2571 |

Fixed incorrect calculations in iso2klems script, thanks to |

Added -features option to rpict, rtrace, and rcontrib to check |
| 2580 |

which features are present or look for specific feature support. |
| 2581 |

This addition was suggested by Peter Apian-Bennewitz as an easier |
| 2582 |

way to determine which version of Radiance is installed and what |

rendering code. There are no current plans to add this to rvu. |

|
| 2586 |

Added falsecolor -odim, -orct, and -c0 options to overlay grid of |
| 2587 |
> |
values on image. This was requested by Rob Shakespeare. |
| 2588 |
> |
|
| 2589 |

Added -i* and -o* options in rhcopy for reading rays from the |
| 2590 |
> |
standard input and writing rays from holodeck to standard output. |
| 2591 |
> |
This will hopefully be useful in combining rholo with rcontrib. |
| 2592 |

|
| 2593 |

Added further checking for coincident (overlapping) flat surfaces, |
| 2594 |
> |
preferring front sides to back sides in the ray intersection |
| 2595 |
> |
calculation. This only applies to rings and faces, as the other |
| 2596 |

surface types would have required additional calculations to |
| 2597 |

make them work. Material transparency is still the primary |

consideration, now followed by ray hit side, followed by |
| 2599 |

modifier definition order in the input. |
| 2600 |

Increased octree and object limits to allow scenes with billions |

of primitives. |
| 2603 |

|
| 2604 |

Made reciprocity averaging default to "off" in bsdf2ttree, as it seems |

==================== |
| 2608 |

Version 6.0 |
| 2609 |
> |
|
| 2610 |
> |
Extensive changes to enable spectral rendering, which defaults to "off" |
| 2611 |
> |
to maintain backwards-compatibility with previous versions, with the |
| 2612 |
> |
exception of the ambient file format, which is changed. The MAXCSAMP |
| 2613 |
> |
macro, which defaults to 24, sets the maximum number of spectral samples. |
| 2614 |
> |
The actual number of samples is set by the "-cs" option, which defaults |
| 2615 |
> |
to 3 for rpict, rtrace, and rcontrib. The latter two programs support |
| 2616 |
> |
straight spectral output, but rpict is initially restricted to |
| 2617 |
> |
tristimulus output pictures. New pattern primitives "spectrum", |
| 2618 |
> |
"specfile", and "specfunc" have been added as a means to specify |
| 2619 |
> |
spectral reflectance, emittance, etc. to materials that still have |
| 2620 |
> |
only 3 color channels. Those RGB channels will still affect the |
| 2621 |
> |
spectrum if used. Unfortunately photon-mapping is currently broken when |
| 2622 |
> |
spectral sampling is enabled, but we will fix this as soon as possible. |
| 2623 |
> |
Calculation overhead appears to be approximately 10-15% for RGB |
| 2624 |
> |
renderings compared to version 5.4a. |
| 2625 |
> |
|
| 2626 |
> |
Added spectral rendering to rvu as well, and made -cs and -cw |
| 2627 |
> |
options standard across the rendering library. I also brought |
| 2628 |
> |
mkillum, ranimove, rsensor, and mksource into the fold. These |
| 2629 |
> |
tools were broken in the initial release. (Hopefully, they are |
| 2630 |
> |
working now, but none have been tested as yet.) |
| 2631 |

There was also an indexing bug in the spectral->RGB conversions |
| 2632 |

that made reds into blues and vice versa, which has been fixed. |

Added i/o for spectral pictures to rmtxop, the first program that can |
| 2635 |

ingest them. (Only rtrace, rcontrib, and rfluxmtx can render them.) |
| 2636 |

New symbolic rmtxop -c options, such as RGB, XYZ, S (for scotopic) |
| 2637 |
> |
and M (for melanopic) make color conversions simpler. Alternatively, |
| 2638 |

a reference matrix or picture may be given and the color space of |
| 2639 |

that file will be used. The -C option takes either a symbolic |
| 2640 |

color space or reference file and is "sticky," so it applies to |
| 2641 |

all subsequent input files that do not have their own -c right ahead |
| 2642 |

of them. |
| 2643 |

Added spectral picture support to rcrop and radcompare. |

Added new utility, rcomb, which is something like a combination |
| 2647 |
> |
of rmtxop and pcomb, it works with all the inputs and |
| 2648 |

outputs that rmtxop handles, but allows for general expressions |
| 2649 |

like those in pcomb for putting matrices together, working on |
| 2650 |
> |
an element at a time. (No resizing of matrices or accessing |
| 2651 |
> |
neighboring elements, as permitted in pcomb.) It saves memory |
| 2652 |
> |
over rmtxop by operating on a row at a time, so can handle |
| 2653 |
> |
input and output matrices with any number of rows. It does |
| 2654 |

provide for a single matrix-multiplication operation at the end, |
| 2655 |

which only requires memory for that final matrix. |

Added support for filtering hyperspectral images to pfilt. |
| 2658 |

|
| 2659 |

Added support for 1- and 3-component float matrix i/o to |
| 2660 |

pcomb to allow for better interoperability. |
| 2661 |

|
| 2662 |

Added support for -co+ option to rtpict, so it can directly |
| 2663 |

produce hyperspectral images. |
| 2664 |

|
| 2665 |

Added new "specdata" and "specpict" primitives to support |
| 2666 |

interpolated spectral data files and hyperspectral images |
| 2667 |

as patterns. |
| 2668 |

|
| 2669 |

Added support for multispectal sampling in rsensor, which will |
| 2670 |

put out as many color channels as specified in any -cs option |
| 2671 |

(default is 3 for RGB). |
| 2672 |

|
| 2673 |

Added ability of mgf2rad to convert spectral data at least |
| 2674 |

for light, glow, plastic, and metal primitive types. Need |
| 2675 |

to use new '-s' option to get new output. |
| 2676 |

Added handling of spectral images to rcode2bmp script. |
| 2678 |

Minor change to rcollate to allow explicit byte records to |
| 2680 |

be any specified length without checks against header input. |
| 2681 |

|
| 2682 |

Added new hemisphere type to rfluxmtx, "h=cie" for CIE sky |
| 2683 |
> |
scanner positions. These are 145 patches with identical |
| 2684 |
> |
row counts to Tregenza, but starting from a different |
| 2685 |

azimuth and reversing row directions at adjacent altitudes. |
| 2686 |

|
| 2687 |

Added optimization for long argument lists and arrays in |
| 2688 |
> |
the calcomp routines used for rendering and in rcalc, etc. |
| 2689 |

|
| 2690 |

Added error estimate spreading to ambient super-sampling |
| 2691 |

algorithm (-as) to improve performance especially in |
| 2692 |

scenes with sharp cut-offs. |
| 2693 |

Added -i option to gendaymtx to match -i option of gendaylit. |
| 2695 |

Changed rcrop so negative #rows or #cols counts back from end. |
| 2698 |

|
| 2699 |

Added rcomb -n option for multi-processing of very large matrices. |
| 2700 |

Added crude ability to read and convert spectra to RGB in ximage, |
| 2718 |

ra_bmp, and ra_rgbe programs. Also updated fast tone-mapping |
| 2719 |

Wrote rxpiece tool that will render pictures using tiling and |
| 2723 |

Only runs on a single machine, however -- now NFS locking on |
| 2725 |

shared volumes. Mainly a demonstration tool for RpictSimulManager |
| 2726 |
