Fixed bug that caused incorrect reporting of non-surface in set when |
| 1383 |
|
mixing meshes and instances. (Thanks to Jack de Valpine for discovery.) |

Fixed inaccuracy in calculation of diffuse transmission in the presence |
| 1386 |
|
of pure specular (Fresnel reflection) using "trans" material. Thanks |

|
to Christoph Reinhart for pointing out the error. |

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. |
| 1486 |
+ |
|
| 1487 |

Last change to total causes it to produce results when it sees an empty |
| 1488 |
+ |
line on the input. This was not intentional, but I decided I like this |
| 1489 |
+ |
behavior so I documented it rather than changing it. |

===================== |
| 1492 |
+ |
Version 3.8 |
| 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 |
+ |
|
| 1511 |
+ |
(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 |
+ |
