Changed rmtxop so it writes out same type as lesser of inputs unless |
| 1963 |
< |
direction otherwise using -f? option. |
| 1963 |
> |
directed otherwise using -f? option. |
| 1964 |
|
|
| 1965 |
|
Changed order of oconv arguments in rfluxmtx so user can specify input |
| 1966 |
|
octree using -i option at the end instead of (or in addition to) a |
| 1967 |
|
list of scene files. |
| 1968 |
|
|
| 1969 |
< |
Added support for argument expansion to rfluxmtx. |

****** COMPATIBILITY CHANGE ******** |
| 1984 |
> |
Changed pabopto2bsdf default behavior to add 90-degree rotation |
| 1985 |
> |
to bring pgII's definition of "up" in line with Klems axis |
| 1986 |
> |
conventions. Introduced a new header variable "upphi" to |
| 1987 |

control this added rotation. Using "#upphi 90" in each |
| 1988 |
> |
BSDF input file gets back the original behavior, where it |
| 1989 |
> |
assumes that the up direction is 90-degrees from the X-axis. |
| 1990 |
> |
The default value of 0 corresponds to PAB's definition of |
| 1991 |
> |
the X-axis as being "up". |
| 1992 |
> |
|
| 1993 |

Fixed bug in rsensor related to having many rows (altitude) and |
| 1994 |

|
| 2002 |

illegal orientation vectors are dealt with more gracefully. |
| 2009 |
> |
|
| 2010 |
> |
Created wrapBSDF tool and incorporated into genBSDF along |

Added color output to genBSDF (+C option) and support for |
| 2021 |
> |
color rendering of Klems and tensor tree data. |
| 2022 |
> |
|
| 2023 |

on opposite side of hemisphere even where sensitivity was zero. |
| 2025 |

transmittance and reflectance. |
| 2029 |
> |
|
| 2030 |

Added ability to read input from commands in dctimestep |
| 2031 |
> |
and rmtxop. |
| 2032 |
> |
|
| 2033 |
> |
Added photon map support to rad. Fixed some double-counting |

| 2041 |
> |
Fixed issue with missing character type identifier at head |
| 2042 |
> |
of genBSDF XML output. |
| 2043 |

|
| 2044 |
> |
Prompted by Roland S., added option to have pcompos -a order |
| 2045 |
> |
rows from top rather than bottom of image. |
| 2046 |
> |
|
| 2047 |
> |
Changed dctimestep to accept matrix as well as BTDF input |
| 2048 |
> |
in the VTDs invocation mode. This permits the output of |
| 2049 |
> |
rmtxop to be used in a pinch when combining multiple BTDF |
| 2050 |
> |
layers, although interreflection between layers is not |
| 2051 |
> |
accounted for properly as it is in the WINDOW program. |
| 2052 |
> |
|
| 2053 |
> |
Added Jan Wienold et al.'s evalglare to distribution. |
| 2054 |

****** COMPATIBILITY CHANGE ******** |
| 2069 |
> |
Added ability to digest color (CIE-XYZ) input in pabopto2bsdf. |
| 2070 |
> |
This change alters the .sir (interpolant) format, so these files |
| 2071 |
> |
will need to be regenerated. Use the new "#colorimetry: CIE-XYZ" tag |
| 2072 |
> |
to enable on input. |
| 2073 |
> |
|
| 2074 |
> |
Rewrote bsdf2klems to support tristimulus color and call wrapBSDF. |
| 2075 |
> |
Did the same for bsdf2ttree. Function specifications still gray only. |
| 2076 |
> |
|
| 2077 |
> |
Reduced a problem where rvu or rholo would be slow to quit when |
| 2078 |
> |
run with many processes on a large model or one with a large |
| 2079 |
> |
ambient file (taking lots of memory). We were waiting for |
| 2080 |
> |
processes to quit one-by-one, which takes some time for each |
| 2081 |
> |
process as it disentangles its shared memory. We now |
| 2082 |
> |
wait for all the processes together, so they can disentangle |
| 2083 |
> |
in parallel. It can still take up to a minute in some cases, |
| 2084 |
> |
but not 10 minutes like it was taking before the fix. |
| 2085 |
> |
|
| 2086 |
> |
Enabled ambient cache value corral for all levels, not just final two. |
| 2087 |
> |
This may reduce errors in certain pathological scenes. |
| 2088 |
> |
|
| 2089 |
> |
Added -in option to rcalc, rlam, and total to limit the number of |
| 2090 |
> |
input records in hopes of circumventing Windows EOF issues on binary data. |
| 2091 |
> |
Also added -on option to rcalc and total for logical symmetry. |
| 2092 |
> |
|
| 2093 |
> |
Increased modifier limit to 10,000 in rcontrib. |
| 2094 |

|
| 2095 |
> |
Fixed issues with glrad and added zoom response to mouse wheel input. |
| 2096 |
> |
|
| 2097 |
> |
Added missing definition of "ashik2" material type to reference manual. |
| 2098 |
> |
|
| 2099 |
> |
Changed genBSDF to calculate device thickness assuming Zmax==0 so |
| 2100 |
> |
pkgBSDF will generate correct proxy geometry. |
| 2101 |
> |
|
| 2102 |
> |
Created pabopto2xyz tool to combine different sensor measurements |
| 2103 |
> |
into a single CIE-XYZ measurement file for color BSDF interpolation. |
| 2104 |
> |
|
| 2105 |
> |
Jan Wienold updated evalglare to version 1.30 |
| 2106 |
> |
|
| 2107 |
> |
Roland Schregle added out-of-core photon mapping routines, which |
| 2108 |
> |
may be compiled using the PMAP_OOC macro. |
| 2109 |
> |
|
| 2110 |
> |
Added -a option to getinfo for easy addition of header lines. |
| 2111 |

|
| 2115 |
> |
Made mkillum more tolerant of non-planar polygons in its sampling routines. |
| 2116 |
> |
|
| 2117 |
> |
Added "-recover" option to genBSDF to pick up where it left off. |
| 2118 |
> |
|
| 2119 |
> |
Fixed genBSDF issue that was created incorrect normalization of |
| 2120 |
> |
Klems output. Thanks to David G-M and Christian Knoflach for |
| 2121 |
> |
discovering the error. Also improved sampling of indirect irradiance |
| 2122 |
> |
that showed some slight bias due to poor sample collision avoidance. |
| 2123 |
> |
|
| 2124 |
> |
Fixed long-standing issue with -aa 0 neglecting textures in calculating |
| 2125 |
> |
surface shading. |
| 2126 |

|
| 2127 |
> |
Fixed bug in ranimove introduced during photon map integration. |
| 2128 |
> |
|
| 2129 |
> |
Added check for steep sections of BSDF in pabopto2bsdf, creating narrower |
| 2130 |
> |
peakes in those places and mitigating some normalization issues. |
| 2131 |
> |
|
| 2132 |
> |
Added view360stereo.cal by Mark Stock to handle 360-degree over/under |
| 2133 |
> |
stereo views. |
| 2134 |
> |
|
| 2135 |
> |
Added MAX2SHADE macro to place limit on number of light sources |
| 2136 |
> |
to precheck for obstructions. (Currently set to 200.) This |
| 2137 |
> |
avoids excessive start-up times for scenes with many light sources. |
| 2138 |
> |
Thanks to Axel Jacobs for pointing out the problem. |
| 2139 |

Rewrote bsdf2rad from ground up and made it a standard part of build. |
| 2143 |

Fixed bug in orientation of Reinhart/Tregenza sample generator in rfluxmtx. |
| 2145 |
> |
|
| 2146 |

Added ability to perform shadow-testing through unproxied BSDFs with strong |
| 2147 |
> |
through (direct-direct) component. |
| 2148 |
> |
|
| 2149 |
> |
Added {+|-}a options to genBSDF and bsdf2ttree for switching off reciprocity |
| 2150 |
> |
averaging. |
| 2151 |
> |
|
| 2152 |
> |
Added bias to see through BTDFs with a strong "through" component |
| 2153 |
> |
rather than scattering view rays. This is in lieu of peak extraction, |
| 2154 |
> |
which looked to be too difficult from an implementation standpoint. |
| 2155 |
> |
|
| 2156 |
> |
Added bsdfview tool analogous to objview but for BSDF files (XML and SIR), |
| 2157 |
> |
which calls bsdf2rad then rad with a few useful default views. |
| 2158 |

division of same-sized matrices. |
| 2167 |
> |
|
| 2168 |

limit of 2048 rather than the default 512 under Windows. |
| 2181 |
> |
|
| 2182 |

Added top-level resources directory with files from Rob Guglielmetti. |
| 2183 |

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

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

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

representatons with strong peaks. |
| 2190 |

|
| 2191 |
> |
Tweaked peak-extraction code to work more reliably. |
| 2192 |

|
| 2195 |

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 |

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

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 |

IESNA63 standards. |
| 2217 |

|
| 2218 |

optional build in src/cv/. |
| 2220 |

|
| 2221 |

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 |

|
| 2245 |
> |
Fixed issue reading very large files (> 2 GBytes) in rcollate. |

|
| 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. |

Improved efficiency of rmtxop in cases where matrix multiplication is |

| 2360 |
> |
|
| 2361 |
> |
Eliminated unnecessary start-up procedures for rtrace when only ray-casting |

Improved isotropic sampling method in bsdf2ttree using "zipper" approach |
| 2365 |

|
| 2367 |

|
| 2401 |

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 |

well-constructed geometry. |
| 2415 |

Added "-s up" option to pabopto2bsdf to allow for 180 degree symmetry, |
| 2417 |

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. |
