# Line 1172 | Line 1172 | Added -N option to rad to start multiple rendering pro

1174   Fixed bug where mesh instances were not being freed, so subsequent calls

1177   Added support in normtiff for floating-point and 16-bit/sample TIFF input
1178   files.
# Line 1256 | Line 1256 | Added -I option to replmarks for mesh instancing.
1256   Made similar change for virtual sources to allow modifiers and aliases
1257   on the mirror and prism types to work properly.

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.

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.
1344 +
1345 + =====================
1346 + Version 3.7
1347 +
1348 + Fixed bug in source occluder cache which caused consistency error
1349 + for distant sources and mist materials.  (Thanks to Mark Stock for
1350 + finding the problem.)
1351 +
1352 + Fixed serious bug in source drawing routines for rpict, where the edges
1353 + of light sources were appearing through obstructions.  (Thanks to Veronica
1354 + Sundstedt for pointing this out.)
1355 +
1356 + (The above were included in the 3.6.1 patch release.)
1357 +
1358 + Changed default temporary directory from /usr/tmp, which doesn't exist
1359 + 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.
