| 1607 |  | not being accounted for properly. | 
| 1608 |  |  | 
| 1609 |  | Added -h option to pcompos and pcomb to eliminate verbose headers. | 
| 1610 | + |  | 
| 1611 | + | ===================== | 
| 1612 | + | Version 3.9 | 
| 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. | 
| 1616 | + |  | 
| 1617 | + | Added byte-swapping input and output to rcalc. | 
| 1618 | + |  | 
| 1619 | + | Additional error-checking for source surfaces. | 
| 1620 | + |  | 
| 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 | 
| 1625 | + | should make a big difference in memory usage, especially for the | 
| 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 | + | Added ability to incorporate LBNL Window 6 bidirectional scattering | 
| 1648 | + | distribution function (BSDF) data in mkillum. |
