Version 3.6 (Released 10/21/04) |
| 1144 |
|
|
| 1145 |
|
Modified 4-byte RGBE encoding routine to avoid problems |
| 1146 |
|
when one or two primary values is negative and the other(s) |
| 1172 |
|
parallel. |
| 1173 |
|
|
| 1174 |
|
Fixed bug where mesh instances were not being freed, so subsequent calls |
| 1175 |
< |
in programs like ranimate would refer to bogus data. |
| 1175 |
> |
in programs like ranimove would refer to bogus data. |
| 1176 |
|
|
| 1177 |
|
Added support in normtiff for floating-point and 16-bit/sample TIFF input |
| 1178 |
|
files. |
| 1180 |
|
Changed marksources() routine (src/rt/source.c) to check all |
| 1181 |
|
primitives in the modifier chain for emitting types, not only |
| 1182 |
|
the first. This permits sources to be described with intervening |
| 1183 |
< |
modifiers before the light/illum/glow primitive. |
| 1183 |
> |
modifiers before the light/illum/glow primitive and allows aliases |
| 1184 |
> |
as well. |
| 1185 |
|
|
| 1186 |
|
Fixed bug in xform where it was neglecting to add transform arguments |
| 1187 |
|
to new mesh primitive. |
| 1191 |
|
|
| 1192 |
|
Changed meta2tga to output correct colors. |

****** COMPATIBILITY CHANGE ******** |
| 1194 |
|
Changed local coordinate index from 32-bits to 16-bits, which requires |
| 1195 |
< |
that Radiance mesh files be recompiled. |
| 1195 |
> |
that Radiance mesh files be recompiled. (Later decided against this |
| 1196 |
> |
change, as it caused problems with some models.) |
| 1197 |
> |
|
| 1198 |
> |
Changed integer tone-mapping routines to better deal with images |
| 1199 |
> |
containing large, constant regions. |
| 1200 |
> |
|
| 1201 |
> |
Improved interaction with rholo -o ogl driver under OS X, which was |
| 1202 |
> |
returning bad values from the depth buffer. |
| 1203 |
> |
|
| 1204 |
> |
Minor bug fix in ranimove where it was restarting processes when it |
| 1205 |
> |
didn't need to. |
| 1206 |
> |
|
| 1207 |
> |
Increased accuracy of default ambient parameters in rpict, rview, and |
| 1208 |
> |
rtrace. In rad program, doubled -ar value, -ad value, and -as value, |
| 1209 |
> |
and decreased -aa value a bit. Also adjusted -lr upwards and -lw |
| 1210 |
> |
downwards. I should have done these things long ago, as processors |
| 1211 |
> |
have been getting faster and faster over the years. |
| 1212 |

|
| 1213 |
> |
Fixed bug discovered by Marcus Jacobs where oconv was dumping core |
| 1214 |
> |
when it was given too many modifiers. |
| 1215 |
> |
|
| 1216 |
> |
Fixed problem with rpict where it was drawing illum sources badly |
| 1217 |
> |
even when they weren't all that small in the view. |
| 1218 |
> |
|
| 1219 |
> |
Added in(i) function to rcalc for more flexible channel evaluation. |
| 1220 |
> |
|
| 1221 |
> |
Replaced all calls to vfork() with regular fork() calls. |
| 1222 |
> |
|
| 1223 |
> |
Fixed bug in glarendx for dgr calculation with sources behind view. |
| 1224 |
> |
|
| 1225 |
> |
Added -p option to histo to print percentages/percentiles r.t. counts. |
| 1226 |
> |
|
| 1227 |
> |
Added a source occluder cache to accelerate shadow testing. This |
| 1228 |
> |
can save up to 50% of the calculation time in scenes with many |
| 1229 |
> |
light sources, especially ones containing large occluders. This |
| 1230 |
> |
optimization may be tuned or switched off with the -DSHADCACHE=N |
| 1231 |
> |
compile switch, where N is the resolution of the shadow cache, or |
| 1232 |
> |
0 to disable it. Since this is purely a time vs. memory trade-off, |
| 1233 |
> |
I decided not to make it a new command-line option. (We already |
| 1234 |
> |
have plenty.) |
| 1235 |
> |
|
| 1236 |
> |
****** COMPATIBILITY CHANGE ******** |
| 1237 |
> |
Changed the following command names to avoid conflicts: |
| 1238 |
> |
rview -> rvu (with symbolic link back to rview) |
| 1239 |
> |
calc -> icalc |
| 1240 |
> |
lam -> rlam |
| 1241 |
> |
gencat -> gencatenary |
| 1242 |
> |
|
| 1243 |
> |
Improved -f option of normpat, which caused odd color changes before. |
| 1244 |
> |
|
| 1245 |
> |
Created pgblur script which does fast Gaussian blur of image without changing |
| 1246 |
> |
its dimensions. This is very useful in certain types of image processing |
| 1247 |
> |
calculations, such as finding or removing low frequencies. |
| 1248 |
> |
|
| 1249 |
> |
****** COMPATIBILITY CHANGE ******** |
| 1250 |
> |
Changed little-used objpict script so that it takes scene files rather than |
| 1251 |
> |
rpict options on the command line, and puts everything into the right |
| 1252 |
> |
coordinate position automatically rather than requiring the user to do it. |
| 1253 |
> |
|
| 1254 |
> |
Added -I option to replmarks for mesh instancing. |
| 1255 |
> |
|
| 1256 |
> |
Made similar change for virtual sources to allow modifiers and aliases |
| 1257 |
> |
on the mirror and prism types to work properly. |
| 1258 |
> |
|
| 1259 |
> |
Rob Guglielmetti added -lw and -lh options to falsecolor to control the |
| 1260 |
> |
legend dimensions. Made it so -lw 0 and/or -lh 0 turns legend off. |
| 1261 |
> |
|
| 1262 |
> |
Made it so pcompos will read everything from a stream even if it doesn't |
| 1263 |
> |
need it, so input commands will not receive a hangup signal. |
| 1264 |
> |
|
| 1265 |
> |
Wrote ra_bmp program to convert to and from Windows BMP files (finally). |
| 1266 |
> |
It's the most horrible image format I've ever seen, and I've seen a lot. |
| 1267 |
> |
|
| 1268 |
> |
Increased -aa default value for all renderers (and also -ad and -as in |
| 1269 |
> |
rview) at Schorsch's suggestion. I think this undid my earlier decrease |
| 1270 |
> |
of -aa last time, which I guess was ill-considered. |
| 1271 |
> |
|
| 1272 |
> |
Modified oconv to keep subdividing the octree if there are too many |
| 1273 |
> |
objects in a voxel even when the -r resolution limit has been |
| 1274 |
> |
reached. This was not done before due to problems with recursion, |
| 1275 |
> |
and still, it will only continue to 256 times the original -r limit. |
| 1276 |
> |
If that isn't enough, then there's probably no hope, anyway. |
| 1277 |
> |
|
| 1278 |
> |
Added -l option to obj2mesh to search for material files in library |
| 1279 |
> |
locations. |
| 1280 |
> |
|
| 1281 |
> |
Increased polygon vertex limit to 512 in obj2mesh and obj2rad and added |
| 1282 |
> |
warning if this limit is exceeded. |
| 1283 |
> |
|
| 1284 |
> |
Added tone-mapping and monitor primary options to ra_bmp. This gives |
| 1285 |
> |
new functionality similar to normtiff and ximage. It would be nice to |
| 1286 |
> |
add this feature to the other ra_* programs as well... someday. |
| 1287 |
> |
|
| 1288 |
> |
Fixed long-standing bug in reported pixel ordering out of certain |
| 1289 |
> |
protate commands. |
| 1290 |
> |
|
| 1291 |
> |
Added -p option to rcalc for "passive mode" that transmits |
| 1292 |
> |
unrecognized input -- useful for substituting data in the |
| 1293 |
> |
middle of a stream. |
| 1294 |
> |
|
| 1295 |
> |
Fixed a very obscure bug in rpict that caused a dark horizontal |
| 1296 |
> |
line in certain cylindrical projections due to improper drawing |
| 1297 |
> |
of the sky dome source in rt/srcdraw.c. |
| 1298 |
> |
|
| 1299 |
> |
Fixed problems with effective ray lengths computed for dielectric |
| 1300 |
> |
and BRTDfunc materials. This was most evident in breakup of holodeck |
| 1301 |
> |
views when VDISTANCE=True. |
| 1302 |
> |
|
| 1303 |
> |
Fixed rad so that 'scene' variable may consist only of inline commands. |
| 1304 |
> |
|
| 1305 |
> |
Fixed bug introduced in shadow caching routines where sources in the |
| 1306 |
> |
middle of spheres were not illuminating properly. Thanks to Guilio |
| 1307 |
> |
Antonutto for spotting this problem. |
| 1308 |
> |
|
| 1309 |
> |
Modified gensky behavior so if time is given with standard time zone |
| 1310 |
> |
designation, any -m option is ignored. |
| 1311 |
> |
|
| 1312 |
> |
Added -n option to mkillum for (shared memory) parallel processing. |
| 1313 |
> |
|
| 1314 |
> |
Fixed a long-standing bug in parallel processing code that only |
| 1315 |
> |
seemed to manifest with the new mkillum -n option, where rtrace |
| 1316 |
> |
would deadlock upon termination. The reason it never showed up |
| 1317 |
> |
before is because I always closed processes in the reverse order |
| 1318 |
> |
of opening them in other programs. I went through and found similar |
| 1319 |
> |
(potential) bugs in the rview device subprocess code and util/netproc.c. |
| 1320 |
> |
|
| 1321 |
> |
Corrected the normalization of the Gaussian reflectance model. This will |
| 1322 |
> |
cause an increase in specularity for low-lying light sources. |
| 1323 |
> |
Thanks to Don Walters of Boeing and Arne Duer of the Univ. of Innsbruck |
| 1324 |
> |
for pointing out this error. The square root used for the two cosines |
| 1325 |
> |
in the denominator of the normalization factor should not be present. |
| 1326 |
> |
This was a serious mistake I made in the original model, which went |
| 1327 |
> |
undiscovered (at least to my knowledge) for over a decade. I think |
| 1328 |
> |
Bruce Walter of Cornell may have known about it, but I never heard |
| 1329 |
> |
the details of his discovery. |
| 1330 |
> |
|
| 1331 |
> |
Enabled the -p option for primary conversion without tone-mapping |
| 1332 |
> |
in ra_bmp. Also provides for XYZE input conversion to RGB. |
| 1333 |
> |
|
| 1334 |
> |
Fixed what I consider a bug in pvalue -o when taking XYZE files on input, |
| 1335 |
> |
where it was inappropriately undoing the exposure value so that it always |
| 1336 |
> |
reported radiance rather than XYZ values with Y in cd/m^2. |
| 1337 |
> |
|
| 1338 |
> |
Made it so ra_bmp only produces run-length encoded 8-bit output for |
| 1339 |
> |
grayscale images that are tone-mapped. This minimizes circumstances |
| 1340 |
> |
under which output scanline order is reversed. |
| 1341 |
> |
|
| 1342 |
> |
Fixed bug in rcalc where it sometimes wasn't parsing the input format |
| 1343 |
> |
correctly. |

Changed default temporary directory from /usr/tmp, which doesn't exist |

on a lot of systems these days, to /tmp. |
| 1360 |

|
| 1361 |

Eliminated many unused files and programs from the distribution, including |
| 1362 |

the following programs that were being built but no longer used: |
| 1363 |
> |
oki20 - printer driver for OkiMate 20 printer (B&W) |
| 1364 |
> |
oki20c - printer driver for OkiMate 20 color printer |
| 1365 |
> |
pcwarp - intended as more general substitute for macbetcal, |
| 1366 |
> |
but never quite worked |
| 1367 |
> |
ra_avs - convert to & from AVS image format |
| 1368 |
> |
ra_bn - convert to & from Barneyscann format |
| 1369 |
> |
ra_pr - convert to & from 8-bit Sun rasterfile format |
| 1370 |

ra_pr24 - convert to & from 24-bit Sun rasterfile format |
| 1371 |
> |
thf2rad - convert GDS "things file" to Radiance scene format |
| 1372 |
> |
If anyone is still wanting any of the above programs, let us know and we'll |
| 1373 |
> |
reinstate it. |
| 1374 |

|
| 1375 |

Fixed bug in pcond's acuity simulation for small view angles (less than |
| 1376 |
> |
4 degrees horizontally or vertically). Thanks to James Lee for figuring |
| 1377 |
> |
this out. |
| 1378 |
> |
|
| 1379 |
> |
Added script to convert to/from ICT's Poskanzer Float Map, which I don't |
| 1380 |
> |
care to support officially due to its machine-dependent byte order. |
| 1381 |
> |
|
| 1382 |
> |
Fixed bug that caused incorrect reporting of non-surface in set when |
| 1383 |
> |
mixing meshes and instances. (Thanks to Jack de Valpine for discovery.) |
| 1384 |
> |
|
| 1385 |
> |
Fixed inaccuracy in calculation of diffuse transmission in the presence |
| 1386 |
> |
of pure specular (Fresnel reflection) using "trans" material. Thanks |
| 1387 |
> |
to Christoph Reinhart for pointing out the error. |
| 1388 |
> |
|
| 1389 |
> |
Made internal change to tone-mapping library to use structure pointer |
| 1390 |
> |
rather than stack, making code re-entrant and more up to modern standards. |
| 1391 |
> |
|
| 1392 |
> |
Added -pd option to handle depth-of-field blur in rpict. This requires |
| 1393 |
> |
that the view directon (-vd option) include focal distance information, |
| 1394 |
> |
which is now preserved by the various view file routines, and reported |
| 1395 |
> |
by the vwright command. |
| 1396 |
> |
|
| 1397 |
> |
Added DBLUR variable to ranimate and pmdblur script to handle simultaneous |
| 1398 |
> |
motion and depth-of-field blurring. Thanks to Visarc for funding this work. |
| 1399 |
> |
|
| 1400 |
> |
Added setting of focus distance in rvu ("focus" command) and rholo |
| 1401 |
> |
('f'/"frame" command). |
| 1402 |
> |
|
| 1403 |
> |
Changed default remote shell in ranimate to "ssh" rather than "rsh", |
| 1404 |
> |
which has been abandoned on most Unix systems due to security issues. |
| 1405 |
> |
|
| 1406 |
> |
Fixed behavior of source primitive using illum with no alternate |
| 1407 |
> |
material. These now become transparent so one can see the sky or |
| 1408 |
> |
light-probe background for use in image-based lighting. Previously, |
| 1409 |
> |
the user needed to specify the background glow as the alternate |
| 1410 |
> |
material for a distant illum source to behave properly. (This still |
| 1411 |
> |
works.) |
| 1412 |
> |
|
| 1413 |

Fixed some minor problems and inconsistencies with 16-bit/channel |
| 1414 |
> |
TIFF i/o in ra_tiff. |
| 1415 |
> |
|
| 1416 |

Created mksource program to generate distant sources for improved |
| 1417 |
> |
image-based lighting with light probes. |
| 1418 |
> |
|
| 1419 |
> |
Changed ambient calculation so that -ad will not limit recursion |
| 1420 |
> |
depth, and a minimum of 27 samples will be sent out for each stored |
| 1421 |
> |
ambient value, or 3 samples if -aa is 0 (caching off). |
| 1422 |
> |
|
| 1423 |
> |
Added -oM option to rtrace to report material (rather than modifier) |
| 1424 |
> |
for cases where actual material is aliased or further up modifier chain. |
| 1425 |
> |
|
| 1426 |
> |
Rearranged the way ray contributions are computed so that it might be |
| 1427 |
> |
possible to use rtrace to derive daylight coefficients and optical |
| 1428 |
> |
transfer functions. The new -oTW option of rtrace produces color |
| 1429 |
> |
contribution weights for each ray, which combined with the -ti (or -tI) |
| 1430 |
> |
option permits the contribution of selected surfaces or sources to |
| 1431 |
> |
be determined. Using the -oTW option, one should also specify |
| 1432 |
> |
options "-dt 0 -aa 0 -as 0" for optimal results. In particular, |
| 1433 |
> |
one cannot expect reasonable tallies with -ab >= 1 and irradiance |
| 1434 |
> |
caching on (-aa > 0). |
| 1435 |
> |
|
| 1436 |
> |
The same code modifications included a change to the indirect computation |
| 1437 |
> |
with caching switched off (-aa 0). Whereas before, the number of secondary |
| 1438 |
> |
rays after the first bounce were half of the previous generation, they are |
| 1439 |
> |
now determined by the surface reflectance, making for a better and faster |
| 1440 |
> |
calculation. It should now be possible to compute many bounces with -aa 0, |
| 1441 |
> |
which used to be prohibitively expensive. |
| 1442 |
> |
|
| 1443 |
> |
Added -T option to xshowtrace to trace rays to light sources. |
| 1444 |
> |
|
| 1445 |
> |
Added meta2bmp program to produce BMP files from metafile graphics. |
| 1446 |
> |
|
| 1447 |
> |
Added cct_x(t) and cct_y(t) to src/cal/cal/blackbody.cal to interpolate |
| 1448 |
> |
CIE chromaticities for particular black-body temperatures. |
| 1449 |
> |
|
| 1450 |
> |
Increased maximum number of input pictures in pcomb and pcompos to 512. |
| 1451 |
> |
|
| 1452 |
> |
Created rtcontrib program for computing ray contribution coefficients. |
| 1453 |
> |
This tool may be used to do standard optical ray tracing or daylight |
| 1454 |
> |
coefficient calculations for annual simulations, among other uses. |
| 1455 |
> |
|
| 1456 |
> |
Added tilde ('~') output option as part of the -o* specification of |
| 1457 |
> |
rtrace. This permits ray trees to be parsed more easily in binary |
| 1458 |
> |
output mode, as needed by rtcontrib. |

|
| 1460 |

Implemented Russian roulette ray termination with -lr <= 0. |
| 1461 |
> |
Made -lr -10 the default in rtcontrib. |
| 1462 |
> |
|
| 1463 |
> |
Made rtcontrib -f option search RAYPATH directories. |
| 1464 |
> |
|
| 1465 |
> |
Made it so -o option of rtcontrib can pipe -o output to a command. |
| 1466 |
> |
|
| 1467 |
> |
Added -if and -of options to total for binary i/o (following rcalc mold). |
| 1468 |
> |
|
| 1469 |
> |
Switched default options in rtrace to use Russian roulette. (Rpict and rvu |
| 1470 |
> |
still use biased ray termination.) |
| 1471 |
> |
|
| 1472 |
> |
Added rtcontrib -r option to recover partial output. |
| 1473 |
> |
|
| 1474 |
> |
Added -u rendering option for pure Monte Carlo sampling. |
| 1475 |
> |
(Got rid of -DMC compile option, which this makes superfluous.) |
| 1476 |
> |
|
| 1477 |
> |
Changed -t option of rlam to accept strings as well as single characters. |
| 1478 |
> |
|
| 1479 |
> |
Fixed bug in rcalc with -l option where it would sometimes go into an |
| 1480 |

infinite loop. |
| 1481 |
> |
|
| 1482 |
> |
Fixed truly ancient bug in bounding box computation for cones, which |
| 1483 |

could (and did) cause missing segments. |
| 1484 |

|
| 1485 |

Added -z option to normtiff to output LZW-compressed files. |

Last change to total causes it to produce results when it sees an empty |

Version 3.8 (Released 10/17/06) |
| 1493 |
> |
|
| 1494 |
> |
Fixed Russian roulette ray termination, which was doing the opposite of |
| 1495 |
> |
what it should have been doing, resulting in overestimated values below |
| 1496 |
> |
minimum ray sampling weight (serious). |
| 1497 |
> |
|
| 1498 |
> |
Changed mksource to use 98th percentile (rather than 99th) for threshold. |
| 1499 |

|
| 1500 |
> |
(Above changes included in 3.7.1 patch release.) |
| 1501 |
> |
|
| 1502 |
> |
Eliminated writing of EXPOSURE= line in ra_tiff -r when source TIFF |
| 1503 |
> |
does not have STONITS set. |
| 1504 |
> |
|
| 1505 |
> |
Fixed bug in ambient calculation that caused black values for multiple |
| 1506 |
> |
bounces in some scenes. Thanks to Mark Stock for creating and sharing |
| 1507 |
> |
the sophisticated test scene that demonstrated this problem. |
| 1508 |
> |
|
| 1509 |
> |
Fixed bug in antimatter using Russian Roulette sampling. |
| 1510 |

(Above changes included in 3.7.2 patch release 22 Aug 2005.) |
| 1512 |
> |
|
| 1513 |
> |
Created fieldcomb script to combine alternate fields in a rendering |
| 1514 |
> |
sequence. (Development generously sponsored by Iebele Abel.) |
| 1515 |
> |
|
| 1516 |
> |
Added missing preload of mesh objects for more efficient memory use |
| 1517 |
> |
during parallel rendering -- this was a serious oversight. |
| 1518 |
> |
|
| 1519 |
> |
Created ran2tiff program to automate exposure setting of animation |
| 1520 |
> |
sequences using a moving histogram in combination with pcond, and |
| 1521 |
> |
converting frames to TIFF. |
| 1522 |
> |
|
| 1523 |
> |
Eliminated SPEED macro from makeall and source tree. |
| 1524 |
> |
|
| 1525 |
> |
Added -pj option to vwrays to allow jittering of sample locations. |
| 1526 |
> |
|
| 1527 |
> |
Fixed bug in rtcontrib where it occasionally missed writing the |
| 1528 |
> |
final bin file. (Pretty serious, actually.) |
| 1529 |
> |
|
| 1530 |
> |
Added -Dfseeko=fseek to MACH= line for linux, as fseeko(3) seems to be |
| 1531 |
> |
broken in current versions of Linux. (Need to remove this later.) |
| 1532 |
> |
|
| 1533 |
> |
Rearranged struct's for better efficiency on 64-bit architectures. |
| 1534 |
> |
|
| 1535 |
> |
Added -i option to rlam so it works with binary input formats. |
| 1536 |
> |
|
| 1537 |
> |
Added rtcontrib -bn option to specify number of bins and fixed bug |
| 1538 |
> |
in recovery of files containing multiple values per record. |
| 1539 |
> |
|
| 1540 |
> |
Added rtcontrib -fo option to write over existing files, which it now |
| 1541 |
> |
refuses to do without this option. |
| 1542 |
> |
|
| 1543 |
> |
Made rtcontrib flush output when handed a zero-length ray vector, |
| 1544 |
> |
to match behavior of rtrace. |
| 1545 |
> |
|
| 1546 |
> |
Improved color scale for falsecolor output. |
| 1547 |
> |
|
| 1548 |
> |
Added threshold test for Fresnel approximation to prevent its use |
| 1549 |
> |
on smooth surfaces with unrealistically low specularities (less than 1.8%). |
| 1550 |
> |
Water has a specular reflectance of 2.1% at room temperture. |
| 1551 |
> |
|
| 1552 |
> |
Removed NICE macro settings in rpict and rtrace, which was slowing down |
| 1553 |
> |
the processes under Mac OS X (10.4) by about 60% due to processor napping. |
| 1554 |
> |
|
| 1555 |
> |
Made xform, replmarks and rad2mgf handle quoted modifiers and names properly. |
| 1556 |
> |
|
| 1557 |
> |
Fixed problem in genblinds, where it was generating slats that were too |
| 1558 |
> |
wide with the +/-r option. (Thanks to Helena Buelow-Huebe for discovering |
| 1559 |
> |
this bug.) |
| 1560 |

|
| 1561 |
> |
Fixed bug in ra_ppm for 16-bit/sample i/o, where it was getting the byte |
| 1562 |
> |
order wrong (apparently). |
| 1563 |
> |
|
| 1564 |
> |
Added -V option to rtcontrib to report actual contributions, rather than |
| 1565 |
> |
just ray coefficients. |
| 1566 |
> |
|
| 1567 |
> |
Fixed bug in ranimate that caused it to fail in continuation of renderings. |
| 1568 |
> |
|
| 1569 |
> |
Renamed librt.a to librtrad.a, to avoid conflict on Solaris. Almost |
| 1570 |
> |
everything now gets linked to -lrtrad instead of -lrt. |
| 1571 |
> |
|
| 1572 |
> |
Fixed problem with large sample sets, so -u+ option now is truly random. |
| 1573 |
> |
Thanks to Rick Mistrick and Younju Yoon for identifying this problem, |
| 1574 |
> |
which was related to a poorly designed hash function. |
| 1575 |
> |
|
| 1576 |
> |
Changed -u+ to be the default setting in rtrace (only). |
| 1577 |
> |
|
| 1578 |
> |
Fixed binary i/o for rlam and vwrays under Windows. |
| 1579 |
> |
|
| 1580 |
> |
Added tmCvLums() to tone-mapping routines using a 16-bit lookup table |
| 1581 |
> |
on IEEE floats, which is also used to improve speed of COLOR conversions, |
| 1582 |
> |
especially on machines with slow log() calls. The first call to |
| 1583 |
> |
tmCvLums(), tmCvGrays(), or tmCvColors() initializes the table. |
| 1584 |
> |
|
| 1585 |
> |
Created optics2rad.csh script to convert from Optics 5 material output |
| 1586 |
> |
to something correct for Radiance. Built on old glazing.cal function, |
| 1587 |
> |
which is actually incorrect so removed from the distribution. |
| 1588 |
> |
|
| 1589 |
> |
Fixed nuisance bug in ximage under some SGI machines that caused it to |
| 1590 |
> |
choose an inappropriate visual and display incorrect colors. (Thanks |
| 1591 |
> |
to Oskar Itzinger for debugging the problem.) |
| 1592 |
> |
|
| 1593 |
> |
Fixed long-standing inaccuracy of pcompos -t and +t thresholding options. |
| 1594 |
> |
|
| 1595 |
> |
Fixed bug in handling of views with tabs rather than spaces. |
| 1596 |

Changed default sky turbidity in gensky from the original default of |
| 1601 |

Added -o option to ra_xyze to produce original pixel values. |
| 1605 |

Re-fixed bug in octree code that caused it to allocate 8 times as |

Fixed pixel alignment in pcomb for size reduction and enlargement. |
| 1641 |

|
| 1642 |

Allow rtcontrib user to set -P and -PP options for persistent rendering. |
| 1643 |

|
| 1965 |

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 |

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 |
