to match behavior of rtrace. |
1545 |
|
|
1546 |
|
Improved color scale for falsecolor output. |
1547 |
+ |
|
1548 |
+ |
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. |
