# 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.
1258  
1259 < Rob Guglielmetti dded -lw and -lh options to falsecolor to control the
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
# Line 1296 | Line 1296 | Fixed a very obscure bug in rpict that caused a dark h
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 lenths computed for dielectric
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  
# Line 1311 | Line 1311 | designation, any -m option is ignored.
1311  
1312   Added -n option to mkillum for (shared memory) parallel processing.
1313  
1314 < Fixed long-standing bug in parallel processing code that only seemed
1315 < to manifest with the new mkillum -n option, where rtrace would
1316 < deadlock upon termination.

1317 > before is because I always closed processes in the reverse order

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.
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 innacuracy 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.
