  | 
just ray coefficients. | 
| 1566 | 
  | 
 | 
| 1567 | 
  | 
Fixed bug in ranimate that caused it to fail in continuation of renderings. | 
| 1568 | 
+ | 
 | 
| 1569 | 
+ | 
Renamed librt.a to librtrad.a, to avoid conflict on Solaris. Almost | 
| 1570 | 
+ | 
everything now gets linked to -lrtrad instead of -lrt. | 
| 1571 | 
+ | 
 | 
| 1572 | 
+ | 
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. | 
| 1575 | 
+ | 
 | 
| 1576 | 
+ | 
Changed -u+ to be the default setting in rtrace (only). | 
| 1577 | 
+ | 
 | 
| 1578 | 
+ | 
Fixed binary i/o for rlam and vwrays under Windows. | 
| 1579 | 
+ | 
 | 
| 1580 | 
+ | 
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. | 
| 1584 | 
+ | 
 | 
| 1585 | 
+ | 
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. | 
| 1588 | 
+ | 
 | 
| 1589 | 
+ | 
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.) | 
| 1592 | 
+ | 
 | 
| 1593 | 
+ | 
Fixed long-standing inaccuracy of pcompos -t and +t thresholding options. | 
| 1594 | 
+ | 
 | 
| 1595 | 
+ | 
Fixed bug in handling of views with tabs rather than spaces. | 
| 1596 | 
+ | 
 | 
| 1597 | 
+ | 
Fixed bug related to alias of alias. | 
| 1598 |

****** COMPATIBILITY CHANGE ******** | 
| 1600 | 
+ | 
Changed default sky turbidity in gensky from the original default of | 
| 1601 | 
+ | 
2.75 to the CIE 110-1994 standard value of 2.45.  Thanks to Marilyne | 
| 1602 | 
+ | 
Anderson of MIT for pointing out this discrepancy. | 
| 1603 | 
+ | 
 | 
| 1604 | 
+ | 
Added -o option to ra_xyze to produce original pixel values. | 
| 1605 | 
+ | 
 | 
| 1606 | 
+ | 
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. | 
| 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 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 | 
+ | 
 | 
| 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 | 
+ | 
****** 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 | 
+ | 
 | 
| 1668 |

===================== | 
| 1669 | 
+ | 
Version 4.0 | 
| 1670 | 
+ | 
 | 
| 1671 | 
+ | 
Added -n option to rvu to provide parallel rendering. | 
| 1672 | 
+ | 
 | 
| 1673 | 
+ | 
****** 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. |
