Modified 4-byte RGBE encoding routine to avoid problems |
| 1146 |

when one or two primary values is negative and the other(s) |

correctly. |

Fixed bug in source occluder cache which caused consistency error |
| 1349 |
|
for distant sources and mist materials. (Thanks to Mark Stock for |
| 1489 |

|
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). |

Created fieldcomb script to combine alternate fields in a rendering |
| 1514 |

sequence. (Development generously sponsored by Iebele Abel.) |
| 1515 |

Added missing preload of mesh objects for more efficient memory use |

during parallel rendering -- this was a serious oversight. |
| 1518 |
> |
|
| 1519 |

Created ran2tiff program to automate exposure setting of animation |

sequences using a moving histogram in combination with pcond, and |
| 1521 |

converting frames to TIFF. |
| 1522 |

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 |

Rearranged struct's for better efficiency on 64-bit architectures. |

refuses to do without this option. |
| 1542 |

|
| 1543 |

Made rtcontrib flush output when handed a zero-length ray vector, |

to match behavior of rtrace. |

|
| 1546 |

Improved color scale for falsecolor output. |

|

Added threshold test for Fresnel approximation to prevent its use |

> |
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 |

Fixed problem in genblinds, where it was generating slats that were too |

wide with the +/-r option. (Thanks to Helena Buelow-Huebe for discovering |

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 |

Changed -u+ to be the default setting in rtrace (only). |

Fixed binary i/o for rlam and vwrays under Windows. |

|
| 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. |
| 1594 |

Fixed bug in handling of views with tabs rather than spaces. |
| 1596 |

Re-fixed bug in octree code that caused it to allocate 8 times as |

in 1999 by Erik Reinhard and Erik Jansen, but the fix they gave me |

Adding ability in mkillum to incorporate BSDF data in calculation. |

Internal interface (raypcalls) now used in place of rtrace process(es). |

Fixed pixel alignment in pcomb for size reduction and enlargement. |

Allow rtcontrib user to set -P and -PP options for persistent rendering. |
