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 | 
  | 
 | 
| 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 | 
+ | 
Added ability to incorporate LBNL Window 6 bidirectional scattering | 
| 1648 | 
+ | 
distribution function (BSDF) data in mkillum. |

****** COMPATIBILITY CHANGE ******** | 
| 1651 | 
+ | 
Fixed long-standing bug in source.cal, which caused it to produce | 
| 1652 | 
+ | 
reversed anisotropic photometric distributions due to the | 
| 1653 | 
+ | 
misorientation of the y-axis.  Thanks to Zack Rogers for discovering | 
| 1654 | 
+ | 
and helping debug this problem. | 
| 1655 | 
+ | 
 | 
| 1656 | 
+ | 
Fixed long-standing bug in replmarks, where triangles with X-side | 
| 1657 | 
+ | 
aligned with Z-axis would cause incorrect rotations.  Thanks to | 
| 1658 | 
+ | 
Zack Rogers for finding this error. | 
| 1659 | 
+ | 
 | 
| 1660 | 
+ | 
Added rsensor program to compute sensor signal for daylighting controls. | 
| 1661 | 
+ | 
Funding for this component was provided by the Architectural Energy | 
| 1662 | 
+ | 
Corporation in Boulder, CO, and directed by Zack Rogers. |
