Fixed Russian roulette ray termination, which was doing the opposite of |
| 1495 |
|
what it should have been doing, resulting in overestimated values below |

|
(Above changes included in 3.7.2 patch release 22 Aug 2005.) |

Fixed bug in rtcontrib where it occasionally missed writing the |

final bin file. (Pretty serious, actually.) |
| 1529 |

|
| 1530 |

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. |
| 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 |

the processes under Mac OS X (10.4) by about 60% due to processor napping. |
| 1554 |

Made xform, replmarks and rad2mgf handle quoted modifiers and names properly. |

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

|
| 1564 |

Added -V option to rtcontrib to report actual contributions, rather than |

just ray coefficients. |

|
| 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 |

|
| 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 |

Fixed long-standing inaccuracy of pcompos -t and +t thresholding options. |

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

| 1623 |

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

Corrected ray weights for material mixtures. |

Reduced the default -n setting for obj2mesh to take better advantage |

Fixed bug in shadow cache where it was adding surfaces with antimatter |

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. |

|
| 1642 |

Allow rtcontrib user to set -P and -PP options for persistent rendering. |
| 1643 |

The only caveat is that -n setting > 1 requires -PP rather than -P. |

Fixed long-standing bug in source.cal, which caused it to produce |

Made backface visibility apply to all material types, including |

The programs may be compiled with the -DOLDAMB option if this is a problem. |

BSDF input file gets back the original behavior, where it |
| 1989 |

assumes that the up direction is 90-degrees from the X-axis. |
| 1990 |

The default value of 0 corresponds to PAB's definition of |

rmtxop to be used in a pinch when combining multiple BTDF |
