# Line 1341 | Line 1341 | 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.
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.
