# Line 1521 | Line 1521 | sequences using a moving histogram in combination with
1521   converting frames to TIFF.
1522  
1523   Eliminated SPEED macro from makeall and source tree.
1524 +
1525 + Added -pj option to vwrays to allow jittering of sample locations.
1526 +
1527 + Fixed bug in rtcontrib where it occasionally missed writing the
1528 + final bin file.  (Pretty serious, actually.)
1529 +
1530 + Added -Dfseeko=fseek to MACH= line for linux, as fseeko(3) seems to be
1531 + broken in current versions of Linux.  (Need to remove this later.)
1532 +
1533 + Rearranged struct's for better efficiency on 64-bit architectures.
1534 +
1535 + Added -i option to rlam so it works with binary input formats.
1536 +
1537 + Added rtcontrib -bn option to specify number of bins and fixed bug
1538 + in recovery of files containing multiple values per record.
1539 +
1540 + Added rtcontrib -fo option to write over existing files, which it now
1541 + refuses to do without this option.
1542 +
1543 + Made rtcontrib flush output when handed a zero-length ray vector,
1544 + 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.
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.
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.
