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.  (I measured 30% less memory usage.) | 
| 1627 | 
  | 
 | 
| 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). | 
| 1667 | 
+ |

===================== | 
| 1669 | 
+ | 
Version 4.0 | 
| 1670 | 
+ | 
 | 
| 1671 | 
+ | 
Added -n option to rvu to provide parallel rendering. | 
| 1672 |

****** 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. |
