| 1140 |  | the stack limit. |

| 1142 |  | ============================== | 
| 1143 | < | Version 3.6 | 
| 1143 | > | 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. | 
| 1344 |  |  | 
| 1345 |  | ===================== | 
| 1346 | < | Version 3.7 | 
| 1346 | > | Version 3.7 (Released 7/25/05) | 
| 1347 |  |  | 
| 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. | 
| 1490 |  |  | 
| 1491 |  | ===================== | 
| 1492 | < | Version 3.8 | 
| 1492 | > | Version 3.8 (Released 10/17/06) | 
| 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 | 
| 1609 |  | Added -h option to pcompos and pcomb to eliminate verbose headers. | 
| 1610 |  |  | 
| 1611 |  | ===================== | 
| 1612 | < | Version 3.9 | 
| 1612 | > | Version 3.9 (Released 3/30/08) | 
| 1613 |  |  | 
| 1614 |  | 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 | 
| 1624 | < | got lost in the slightly borken release process at the time.  This | 
| 1624 | > | got lost in the slightly broken release process at the time.  This | 
| 1625 |  | should make a big difference in memory usage, especially for the | 
| 1626 | < | new mesh primitive. | 
| 1626 | > | new mesh primitive.  (I measured 30% less memory usage.) | 
| 1627 | > |  | 
| 1628 | > | Corrected ray weights for material mixtures. | 
| 1629 | > |  | 
| 1630 | > | Reduced the default -n setting for obj2mesh to take better advantage | 
| 1631 | > | of the smaller octree structure size. | 
| 1632 | > |  | 
| 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. | 
| 1638 | > | 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 | > | Added -c option to rtcontrib to facilitate cumulative calculations. | 
| 1646 | > |  | 
| 1647 | > | ****** COMPATIBILITY CHANGE ******** | 
| 1648 | > | 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 | > |  | 
| 1657 | > | Added rsensor program to compute sensor signal for daylighting controls. | 
| 1658 | > | Funding for this component was provided by the Architectural Energy | 
| 1659 | > | Corporation in Boulder, CO, and directed by Zack Rogers. | 
| 1660 | > |  | 
| 1661 | > | Added "planisphere" (stereographic) fisheye view type for traditional | 
| 1662 | > | 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 | > | record (which can now be done with -c 0). |

| 1668 | > | ===================== | 
| 1669 | > | Version 4.0 (Released 3/12/10) | 
| 1670 | > |  | 
| 1671 | > | Added -n option to rvu to provide parallel rendering. | 
| 1672 | > |  | 
| 1673 | > | ****** COMPATIBILITY CHANGE ******** | 
| 1674 | > | 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 | 
| 1677 | > | extensions were never more than a convention in Radiance, this does not | 
| 1678 | > | affect operation, but may require the update of scripts, etc. written | 
| 1679 | > | by others that assume the ".pic" suffix for Radiance output. | 
| 1680 | > |  | 
| 1681 | > | Added -N option to objview to support multiprocessing. | 
| 1682 | > |  | 
| 1683 | > | Improved sampling of circular sources (source, sphere, ring types) with | 
| 1684 | > | 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 | 
| 1688 | > | command path in each case.  Change suggested by Lars Grobe based | 
| 1689 | > | on similar Radzilla (radz) facility by Carsten Bauer. | 
| 1690 | > |  | 
| 1691 | > | Fixed rad -v N specification to use actual view name if one. | 
| 1692 | > |  | 
| 1693 | > | Fixed error in mkillum calculation where it neglected indirect | 
| 1694 | > | source contributions from BTDF illum's. | 
| 1695 | > |  | 
| 1696 | > | Added GMT and LATLONG header lines for Greenwich Mean Time and | 
| 1697 | > | degrees North Latitude / East Longitude. | 
| 1698 | > |  | 
| 1699 | > | Added gendaylit to distribution (finally). | 
| 1700 | > |  | 
| 1701 | > | Added ability in vwright(1) to get view from command line arguments. | 
| 1702 | > |  | 
| 1703 | > | Created genklemsamp(1) utility to generate samples suitable for | 
| 1704 | > | BSDF-based annual calculations.  This is the first Perl script to | 
| 1705 | > | be added to Radiance.  Hopefully, others will follow. | 
| 1706 | > |  | 
| 1707 | > | Added klems_int.cal file to compute Klems bins for windows. | 
| 1708 | > |  | 
| 1709 | > | Created genskyvec  utility to sample a particular sky and | 
| 1710 | > | evaluate average radiance over the standard Tregenza sky patches. | 
| 1711 | > |  | 
| 1712 | > | Created dctimestep program to compute a set of sensor values or | 
| 1713 | > | a combined image for a particular time using the daylight | 
| 1714 | > | coefficient method. | 
| 1715 | > |  | 
| 1716 | > | Created src/rt/rayfifo.c for first-in/first-out handling of | 
| 1717 | > | multiprocessing by raypcalls.c. | 
| 1718 | > |  | 
| 1719 | > | Added -n option to rtrace for executing on multiple cores |

| 1725 | > | Changed ranimate behavior so remote login under a different user |

| 1728 | > |  |

| 1733 | > | Changed rad behavior with -N >1 on single view to call rpiece. |
