| 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. | 
| 1608 | + |  | 
| 1609 | + | Added -h option to pcompos and pcomb to eliminate verbose headers. |
