Increased -aa default value for all renderers (and also -ad and -as in |

Renamed librt.a to librtrad.a, to avoid conflict on Solaris. Almost |
| 1570 |

everything now gets linked to -lrtrad instead of -lrt. |

Fixed problem with large sample sets, so -u+ option now is truly random. |
| 1573 |

Thanks to Rick Mistrick and Younju Yoon for identifying this problem, |
| 1574 |

which was related to a poorly designed hash function. |

Changed -u+ to be the default setting in rtrace (only). |

Fixed binary i/o for rlam and vwrays under Windows. |

Added tmCvLums() to tone-mapping routines using a 16-bit lookup table |
| 1581 |

on IEEE floats, which is also used to improve speed of COLOR conversions, |
| 1582 |

especially on machines with slow log() calls. The first call to |
| 1583 |

tmCvLums(), tmCvGrays(), or tmCvColors() initializes the table. |

Created optics2rad.csh script to convert from Optics 5 material output |
| 1586 |

to something correct for Radiance. Built on old glazing.cal function, |
| 1587 |

which is actually incorrect so removed from the distribution. |

Fixed nuisance bug in ximage under some SGI machines that caused it to |
| 1590 |

choose an inappropriate visual and display incorrect colors. (Thanks |
| 1591 |

to Oskar Itzinger for debugging the problem.) |

Fixed long-standing inaccuracy of pcompos -t and +t thresholding options. |

Fixed bug in handling of views with tabs rather than spaces. |

Changed default sky turbidity in gensky from the original default of |

2.75 to the CIE 110-1994 standard value of 2.45. Thanks to Marilyne |
| 1602 |

Anderson of MIT for pointing out this discrepancy. |

Added -o option to ra_xyze to produce original pixel values. |

Fixed bug in tracing of virtual sources, where intervening glazing was |
| 1607 |

not being accounted for properly. |
| 1608 |

| 1609 |

Added -h option to pcompos and pcomb to eliminate verbose headers. |

Version 3.9 |

Added -spec option to falsecolor to restore original spectral color scale. |
| 1615 |

Also added "-s auto" option to automatically set the maximum value. |

Added byte-swapping input and output to rcalc. |

Additional error-checking for source surfaces. |

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 |

should make a big difference in memory usage, especially for the |
| 1626 |

new mesh primitive. (I measured 30% less memory usage.) |

Corrected ray weights for material mixtures. |

Reduced the default -n setting for obj2mesh to take better advantage |

of the smaller octree structure size. |

Fixed bug in shadow cache where it was adding surfaces with antimatter |

holes cut in them to the obstructor list. Thanks to John Mardaljevic |

Adding ability in mkillum to incorporate BSDF data in calculation. |

Internal interface (raypcalls) now used in place of rtrace process(es). |

Fixed pixel alignment in pcomb for size reduction and enlargement. |

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. |

Added -c option to rtcontrib to facilitate cumulative calculations. |

Added ability to incorporate LBNL Window 6 bidirectional scattering |
