|
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 |
+ |
|
| 1599 |
+ |
****** 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 |
+ |
Added ability to incorporate LBNL Window 6 bidirectional scattering |
| 1648 |
+ |
distribution function (BSDF) data in mkillum. |
| 1649 |
+ |
|
| 1650 |
+ |
****** 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. |
