Version 3.6 (Released 10/21/04) |
| 1144 |
|
|
| 1145 |
|
Modified 4-byte RGBE encoding routine to avoid problems |
| 1146 |
|
when one or two primary values is negative and the other(s) |
| 1343 |
|
correctly. |

|
|
| 1348 |
|
Fixed bug in source occluder cache which caused consistency error |
| 1349 |
|
for distant sources and mist materials. (Thanks to Mark Stock for |
| 1489 |
|
behavior so I documented it rather than changing it. |

|
Fixed Russian roulette ray termination, which was doing the opposite of |
| 1495 |
|
what it should have been doing, resulting in overestimated values below |
| 1609 |
|
Added -h option to pcompos and pcomb to eliminate verbose headers. |

|
Added -spec option to falsecolor to restore original spectral color scale. |
| 1615 |
|
Also added "-s auto" option to automatically set the maximum value. |
| 1621 |
|
Re-fixed bug in octree code that caused it to allocate 8 times as |
| 1622 |
|
much memory as it actually used(!) -- this was pointed out way back |
| 1623 |
|
in 1999 by Erik Reinhard and Erik Jansen, but the fix they gave me |

got lost in the slightly borken release process at the time. This |

new mesh primitive. (I measured 30% less memory usage.) |

Corrected ray weights for material mixtures. |
| 1629 |

|

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

of the smaller octree structure size. |

|
| 1633 |

Fixed bug in shadow cache where it was adding surfaces with antimatter |
| 1634 |

holes cut in them to the obstructor list. Thanks to John Mardaljevic |
| 1635 |

for discovering and reporting the problem. |
| 1636 |

|
| 1637 |

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

Internal interface (raypcalls) now used in place of rtrace process(es). |
| 1639 |

|
| 1640 |

Fixed pixel alignment in pcomb for size reduction and enlargement. |
| 1641 |
> |
|
| 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. |
| 1644 |

|
| 1645 |

Fixed long-standing bug in source.cal, which caused it to produce |
| 1649 |

reversed anisotropic photometric distributions due to the |
| 1650 |

misorientation of the y-axis. Thanks to Zack Rogers for discovering |
| 1651 |

and helping debug this problem. |
| 1652 |

|
| 1653 |

Fixed long-standing bug in replmarks, where triangles with X-side |
| 1654 |

aligned with Z-axis would cause incorrect rotations. Thanks to |
| 1655 |

Zack Rogers for finding this error. |
| 1656 |

Added rsensor program to compute sensor signal for daylighting controls. |

daylighting analysis. Feature requested & explained by Axel Jacobs. |
| 1663 |

|
| 1664 |

Modified -c option to rtcontrib so it can take a number of input |
| 1665 |

rays to average over, rather than only produce a single accumulated |
| 1666 |

Changed ".pic" extension to ".hdr" in all sources and documentation |
| 1675 |

to improve interoperability with other software, since this has become |
| 1676 |
> |
the de facto extension for Radiance RGBE and XYZE pictures. Since file |

extensions were never more than a convention in Radiance, this does not |

by others that assume the ".pic" suffix for Radiance output. |

Added -N option to objview to support multiprocessing. |

quite a bit of help from David Geisler-Moroder. |
| 1685 |

|
| 1686 |

Added "rpict" and "rvu" variables to rad, and made these as well as |
| 1687 |

the "oconv", "mkillum" and "pfilt" variables accept an alternate |

Created genklemsamp(1) utility to generate samples suitable for |

a combined image for a particular time using the daylight |
