# Line 1607 | Line 1607 | Fixed bug in tracing of virtual sources, where interve
1607   not being accounted for properly.
1608  
1609   Added -h option to pcompos and pcomb to eliminate verbose headers.

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.
