|
Added threshold test for Fresnel approximation to prevent its use |
| 1549 |
|
on smooth surfaces with unrealistically low specularities (less than 1.8%). |
| 1550 |
|
Water has a specular reflectance of 2.1% at room temperture. |
| 1551 |
+ |
|
| 1552 |
+ |
Removed NICE macro settings in rpict and rtrace, which was slowing down |
| 1553 |
+ |
the processes under Mac OS X (10.4) by about 60% due to processor napping. |
| 1554 |
+ |
|
| 1555 |
+ |
Made xform, replmarks and rad2mgf handle quoted modifiers and names properly. |
| 1556 |
+ |
|
| 1557 |
+ |
Fixed problem in genblinds, where it was generating slats that were too |
| 1558 |
+ |
wide with the +/-r option. (Thanks to Helena Buelow-Huebe for discovering |
| 1559 |
+ |
this bug.) |
| 1560 |
+ |
|
| 1561 |
+ |
Fixed bug in ra_ppm for 16-bit/sample i/o, where it was getting the byte |
| 1562 |
+ |
order wrong (apparently). |
| 1563 |
+ |
|
| 1564 |
+ |
Added -V option to rtcontrib to report actual contributions, rather than |
| 1565 |
+ |
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 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. |
