bounces in some scenes. Thanks to Mark Stock for creating and sharing |
| 1507 |
|
the sophisticated test scene that demonstrated this problem. |

|

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 |
+ |
|
| 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. |
