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 |
| 2572 |
+ |
help from Jacob Jonnson. |
| 2573 |
+ |
|
| 2574 |
+ |
Updated official copyright and license according to new wording |
| 2575 |
+ |
provided by Jean Haemmerle at the LBNL Intellectual Property Office. |
| 2576 |
+ |
Both were copied verbatim from e-mail I received from Taoning Wang |
| 2577 |
+ |
on 8/20/2022. |
| 2578 |
+ |
|
| 2579 |
+ |
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 |
| 2583 |
+ |
it supports, and is timely as we begin our refactoring of the |
| 2584 |
+ |
rendering code. There are no current plans to add this to rvu. |
| 2585 |
+ |
|
| 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 |
| 2598 |
+ |
consideration, now followed by ray hit side, followed by |
| 2599 |
+ |
modifier definition order in the input. |
