Version 5.1 (Released 8/17/2017) |
| 2062 |
|
|
| 2063 |
|
Fixed issue with vchars.mta and symbols.mta not being installed in |
| 2064 |
|
the appropriate metafile library location, with help from Rob G. |
| 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 averaging. |

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. |

Version 5.2 (Release October 8, 2018) |
| 2161 |
> |
|
| 2162 |
> |
Created psketch program to apply non-photorealistic rendering to selected |
| 2163 |
> |
objects, identified by modifier name(s). |
| 2164 |
> |
|
| 2165 |

Added '*' and '/' operations to rmtxop for element-wise multiplication and |
| 2166 |
> |
division of same-sized matrices. |
| 2167 |
> |
|
| 2168 |

Changed falsecolor so "-s" option is adjusted to match legend if one. |
| 2169 |

Falsecolor legend changes and improvements by David G-M and Stephen W. |
| 2171 |

|
| 2172 |

Fixed bug in peak extraction code that generated |
| 2173 |
> |
"Bad call to SDqueryTreProjSA" error, reported by Lars Grobe. |
| 2174 |
> |
|
| 2175 |
> |
Increased maximum luminance to 10^7 in pcond to fix issue noticed |
| 2176 |
> |
by Axel Jacobs where veiling glare not added for the sun under |
| 2177 |
> |
some conditions. |
| 2178 |
> |
|
| 2179 |
> |
Increased maximum number of open files in rcontrib to the system upper |
| 2180 |
> |
limit of 2048 rather than the default 512 under Windows. |
| 2181 |
> |
|
| 2182 |
> |
Added top-level resources directory with files from Rob Guglielmetti. |
| 2183 |
> |
|
| 2184 |
> |
Improved accuracy for peaky BSDFs and small light sources. |
| 2185 |
> |
|
| 2186 |
> |
Fixed issue with pmapdump noted by Axel Jacobs. |
| 2187 |
> |
|
| 2188 |
> |
Improved accuracy of bsdf2ttree when converting scattering interpolation |
| 2189 |
> |
representatons with strong peaks. |
| 2190 |
> |
|
| 2191 |
> |
Tweaked peak-extraction code to work more reliably. |
| 2192 |
> |
|
| 2193 |
> |
Georg Mischler updated SCons build system. |
| 2194 |
> |
|
| 2195 |
> |
Rob Guglielmetti and Alex Swindler updated CMake build system. |
| 2196 |
> |
|
| 2197 |
> |
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 |
> |
Added ability to move forwards/backwards specified distance in rvu "origin" |
| 2203 |
> |
command. Feature requested by John Mardaljevic, who essentially owns this |
| 2204 |
> |
command, now. |
| 2205 |
> |
|
| 2206 |
> |
Reduced bias in ambient super-sampling method. |
| 2207 |
> |
|
| 2208 |

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 |
> |
with rcalc, calc, and rendering tools. |
| 2214 |
> |
|
| 2215 |
> |
Worked with Randolph Fritz to fix some issues with ies2rad and newer |
| 2216 |
> |
IESNA63 standards. |
| 2217 |
> |
|
| 2218 |
> |
Resurrected original bsdf2rad test program, renaming it bsdf2rado. Still an |
| 2219 |
> |
optional build in src/cv/. |
| 2220 |
> |
|
| 2221 |
> |
Fixed bug in rcontrib with virtual sources, where pretest was adding |
| 2222 |
> |
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 |
> |
for comparing BSDFs. |
| 2232 |
> |
|
| 2233 |
> |
Fixed issue with pfilt -m option and uneven image size changes pointed |
| 2234 |
> |
out by Rob Shakespeare. |
| 2235 |
> |
|
| 2236 |
> |
Updates to evalglare and gendaylit from Jan Wienold, including new |
| 2237 |

colored sky option. |

Version 5.3 (Released September 1, 2020) |
| 2241 |
> |
|
| 2242 |
> |
Created radcompare program to compare Radiance tool output to reference outputs |
| 2243 |
> |
during unit-testing. |
| 2244 |
> |
|
| 2245 |
> |
Fixed issue reading very large files (> 2 GBytes) in rcollate. |
| 2246 |
> |
|
| 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. |

|
| 2253 |

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. |
| 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. |

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. |

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 |

========================= |
| 2386 |

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. |
| 2462 |

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 |

common "luminous opening" shapes in the 1995, 2002, and 2019 versions |

Added support for depth-of-field blurring in vwrays using -pd option. |
| 2494 |

Also, made -c count work with vwrays -i, producing multiple samples |

option was added to rtpict, which calls on vwrays for its samples. |

Added -O option to pvalue and pextrem to report watts/sr/m^2 even if |

picture is XYZE. |
| 2507 |

|
| 2508 |

binary file formats to enable memory-mapping. Implemented memory-mapped |

Removed ambient value sorting, which was written when ambient caches |
| 2513 |

Added iso2klems script to compute a Klems BSDF based on specular |

and diffuse measurements as a function of incident angle. |
| 2520 |

Created rcrop utility for cropping matrices and pictures more |

Changed pcomb so -o option elides original exposure values |

from indented source headers. |
| 2535 |

|
| 2536 |

Added getinfo -r option, which is similar to -a except it will |

replace indicated lines with new ones. |

Slight change to vwrays -d option to not spit out "-ld-", and to |

Added automatic overture calculation to rtpict with -n > 1 if |

ambient cache is on and file is named. If straight image output |

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

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

in WINDOW. |
| 2556 |

|
| 2557 |

Eliminated most aiming failures for triangular light sources, at the |

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

Added source obstruction test to statistics being kept on which |

Added diffuse components into maximum directional hemispherical |

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

==================== |
| 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. |
| 2633 |
> |
|
| 2634 |
> |
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 |
> |
|
| 2644 |
> |
Added spectral picture support to rcrop and radcompare. |
| 2645 |
> |
|
| 2646 |
> |
Added new utility, rcomb, which is hard to type and hard to |
| 2647 |
> |
pronounce, and probably equally difficult to use. Sort of a |
| 2648 |
> |
combination of rmtxop and pcomb, it works with all the inputs and |
| 2649 |
> |
outputs that rmtxop handles, but allows for general expressions |
| 2650 |
> |
like those in pcomb for putting matrices together, working on |
| 2651 |
> |
an element at a time. (No resizing of matrices or accessing |
| 2652 |
> |
neighboring elements, as permitted in pcomb.) It saves memory |
| 2653 |
> |
over rmtxop by operating on a row at a time, so can handle |
| 2654 |
> |
input and output matrices with any number of rows. It does |
| 2655 |
> |
provide for a single matrix-multiplication operation at the end, |
| 2656 |
> |
which only requires memory for that final matrix. |
| 2657 |
> |
|
| 2658 |
> |
Added support for filtering hyperspectral images to pfilt. |
| 2659 |
> |
|
| 2660 |
> |
Added support for 1- and 3-component float matrix i/o to |
| 2661 |
> |
pcomb to allow for better interoperability. |
| 2662 |
> |
|
| 2663 |
> |
Added support for -co+ option to rtpict, so it can directly |
| 2664 |
> |
produce hyperspectral images. |
