|
Fixed bug in source occluder cache which caused consistency error |
1349 |
|
for distant sources and mist materials. (Thanks to Mark Stock for |
1489 |

Fixed Russian roulette ray termination, which was doing the opposite of |
1495 |
|
what it should have been doing, resulting in overestimated values below |

Also added "-s auto" option to automatically set the maximum value. |
1621 |
|
Re-fixed bug in octree code that caused it to allocate 8 times as |
1622 |
|
much memory as it actually used(!) -- this was pointed out way back |
1623 |
|
in 1999 by Erik Reinhard and Erik Jansen, but the fix they gave me |

Introduced new Hessian-based error control in irradiance caching (ambient) |
1946 |

calculation. Since the format of the stored ambient values is different, |
1947 |

the old files will be rejected with an error message and must be removed. |
1948 |

The programs may be compiled with the -DOLDAMB option if this is a problem. |
1949 |

|
1950 |

Added -p option to rcontrib to set function file parameters on a per-modifier |
1951 |

basis to simplify bin evaluation. |
1952 |

|
1953 |
> |
Created rfluxmtx program to compute flux transfer matrices from a sender |

Version 5.0 (Released 9/18/2015) |
1961 |

Changed rmtxop so it writes out same type as lesser of inputs unless |
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 and bug fixes. |
1970 |
> |
|
1971 |
> |
Fixed bug in indirect hemisphere sampling for some corner cases. |
1972 |
> |
|
1973 |
> |
Added default specular lobe to BSDF interpolation. |
1974 |

****** 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 |
> |
few columns (azimuth) in sensitivity file. |
1995 |
> |
|
1996 |
> |
Fixed floating point round-off error in new Hessian calculation |
1997 |

|
2020 |

|
2023 |

Fixed another bug in rsensor that caused rays to be generated |
2024 |

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 |

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 |
> |
|
2055 |

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 |

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. |

Added missing definition of "ashik2" material type to reference manual. |
2098 |

Changed genBSDF to calculate device thickness assuming Zmax==0 so |
2100 |

pkgBSDF will generate correct proxy geometry. |
2101 |

|
2102 |

2118 |
> |
|
2119 |
> |
Fixed genBSDF issue that was created incorrect normalization of |
2120 |

discovering the error. Also improved sampling of indirect irradiance |
2122 |

Fixed bug in ranimove introduced during photon map integration. |
2128 |

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 |

averaging. |
2151 |
> |
|
2152 |
> |
Added bias to see through BTDFs with a strong "through" component |

|
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 |

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 |

|
2361 |

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

If the materials are both transparent or both opaque, then whichever |

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 |

2432 |

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 |

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 |

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 |

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 |

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 |

|
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 |

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 |

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 |

Fixed issue with divide-by-zero errors in the ambient super-sampling |
2549 |

routine discovered by Jon Sargent of Solemma. This affected regions |
2550 |

Updated Klems Half- and Quarter-bases to match angles currently used |
2555 |

in WINDOW. |
2556 |

|
2557 |

Increased maximum set size to 8191 to avoid set overflow errors. |

Added source obstruction test to statistics being kept on which |

|
2567 |

==================== |
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 |

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 |

spectral sampling is enabled, but we will fix this as soon as possible. |

tools were broken in the initial release. (Hopefully, they are |

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.) |

New symbolic rmtxop -c options, such as RGB, XYZ, S (for scotopic) |
2637 |

and M (for melanopic) make color conversions simpler. |

Also added spectral picture support to rcrop and radcompare. |
