| 1143 | < | Version 3.6 | 
| 1143 | > | Version 3.6 (Released 10/21/04) | 
| 1144 |  |  | 
| 1145 |  | Modified 4-byte RGBE encoding routine to avoid problems | 
| 1146 |  | when one or two primary values is negative and the other(s) | 
| 1343 |  | correctly. | 
| 1344 |  |  |

| 1346 | < | Version 3.7 | 
| 1346 | > | Version 3.7 (Released 7/25/05) | 
| 1347 |  |  | 
| 1348 |  | Fixed bug in source occluder cache which caused consistency error | 
| 1349 |  | for distant sources and mist materials.  (Thanks to Mark Stock for | 
| 1489 |  | behavior so I documented it rather than changing it. | 
| 1490 |  |  | 
| 1491 |  | ===================== | 
| 1492 | < | Version 3.8 | 
| 1492 | > | Version 3.8 (Released 10/17/06) | 
| 1493 |  |  | 
| 1494 |  | Fixed Russian roulette ray termination, which was doing the opposite of | 
| 1495 |  | what it should have been doing, resulting in overestimated values below | 
| 1609 |  | Added -h option to pcompos and pcomb to eliminate verbose headers. | 
| 1610 |  |  | 
| 1611 |  | ===================== | 
| 1612 | < | Version 3.9 | 
| 1612 | > | Version 3.9 (Released 3/30/08) | 
| 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. | 
| 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 | – |  | 
| 1647 |  | ****** COMPATIBILITY CHANGE ******** | 
| 1648 |  | Fixed long-standing bug in source.cal, which caused it to produce | 
| 1649 |  | reversed anisotropic photometric distributions due to the | 
| 1660 |  |  | 
| 1661 |  | Added "planisphere" (stereographic) fisheye view type for traditional | 
| 1662 |  | daylighting analysis.  Feature requested & explained by Axel Jacobs. | 
| 1663 | + |  | 
| 1664 | + | Modified -c option to rtcontrib so it can take a number of input | 
| 1665 | + | rays to average over, rather than only produce a single accumulated | 
| 1666 | + | record (which can now be done with -c 0). | 
| 1667 | + |  | 
| 1668 | + | ===================== | 
| 1669 | + | Version 4.0 (Released 3/12/10) | 
| 1670 | + |  | 
| 1671 | + | Added -n option to rvu to provide parallel rendering. | 
| 1672 | + |  | 
| 1673 | + | ****** COMPATIBILITY CHANGE ******** | 
| 1674 | + | Changed ".pic" extension to ".hdr" in all sources and documentation | 
| 1675 | + | to improve interoperability with other software, since this has become | 
| 1676 | + | the de facto extension for Radiance RGBE and XYZE pictures.  Since file | 
| 1677 | + | extensions were never more than a convention in Radiance, this does not | 
| 1678 | + | affect operation, but may require the update of scripts, etc. written | 
| 1679 | + | by others that assume the ".pic" suffix for Radiance output. | 
| 1680 | + |  | 
| 1681 | + | Added -N option to objview to support multiprocessing. | 
| 1682 | + |  | 
| 1683 | + | Improved sampling of circular sources (source, sphere, ring types) with | 
| 1684 | + | quite a bit of help from David Geisler-Moroder. | 
| 1685 | + |  | 
| 1686 | + | Added "rpict" and "rvu" variables to rad, and made these as well as | 
| 1687 | + | the "oconv", "mkillum" and "pfilt" variables accept an alternate | 
| 1688 | + | command path in each case.  Change suggested by Lars Grobe based | 
| 1689 | + | on similar Radzilla (radz) facility by Carsten Bauer. | 
| 1690 | + |  | 
| 1691 | + | Fixed rad -v N specification to use actual view name if one. | 
| 1692 | + |  | 
| 1693 | + | Fixed error in mkillum calculation where it neglected indirect | 
| 1694 | + | source contributions from BTDF illum's. | 
| 1695 | + |  | 
| 1696 | + | Added GMT and LATLONG header lines for Greenwich Mean Time and | 
| 1697 | + | degrees North Latitude / East Longitude. | 
| 1698 | + |  | 
| 1699 | + | Added gendaylit to distribution (finally). | 
| 1700 | + |  | 
| 1701 | + | Added ability in vwright(1) to get view from command line arguments. | 
| 1702 | + |  | 
| 1703 | + | Created genklemsamp(1) utility to generate samples suitable for | 
| 1704 | + | BSDF-based annual calculations.  This is the first Perl script to | 
| 1705 | + | be added to Radiance.  Hopefully, others will follow. | 
| 1706 | + |  | 
| 1707 | + | Added klems_int.cal file to compute Klems bins for windows. | 
| 1708 | + |  | 
| 1709 | + | Created genskyvec  utility to sample a particular sky and | 
| 1710 | + | evaluate average radiance over the standard Tregenza sky patches. | 
| 1711 | + |  | 
| 1712 | + | Created dctimestep program to compute a set of sensor values or | 
| 1713 | + | a combined image for a particular time using the daylight | 
| 1714 | + | coefficient method. | 
| 1715 | + |  | 
| 1716 | + | Created src/rt/rayfifo.c for first-in/first-out handling of | 
| 1717 | + | multiprocessing by raypcalls.c. | 
| 1718 | + |  | 
| 1719 | + | Added -n option to rtrace for executing on multiple cores | 
| 1720 | + | using new rayfifo calls. | 
| 1721 | + |  | 
| 1722 | + | ===================== | 
| 1723 | + | Version 4.1 (Released 11/04/2011) | 
| 1724 | + |  | 
| 1725 | + | Changed ranimate behavior so remote login under a different user | 
| 1726 | + | doesn't necessarily require the presence of the originating user's | 
| 1727 | + | home directory. | 
| 1728 | + |  | 
| 1729 | + | Changed standard transmission function normalization back to what | 
| 1730 | + | it was in version 3.5, following recommendation of David Geisler-Moroder, | 
| 1731 | + | who pointed out that the revised BTDF increased too much at grazing. | 
| 1732 | + |  | 
| 1733 | + | Changed rad behavior with -N >1 on single view to call rpiece. | 
| 1734 | + |  | 
| 1735 | + | Updated SCons build system for MINGW compilation, thanks to Christian | 
| 1736 | + | Kohler. | 
| 1737 | + |  | 
| 1738 | + | Added -u option to rlam for unbuffered output. | 
| 1739 | + |  | 
| 1740 | + | Modified dctimestep to accept sky vector and daylight coefficient matrix | 
| 1741 | + | or list of images to sum together, as suggested by Andy McNeil. | 
| 1742 | + |  | 
| 1743 | + | Created genBSDF script to generate BSDF in Windows XML format. | 
| 1744 | + |  | 
| 1745 | + | Modified mkillum to accept detailed geometry from BSDF XML files. | 
| 1746 | + |  | 
| 1747 | + | Altered obj2rad to ignore zero normals (thanks to Jack de Valpine for | 
| 1748 | + | suggestions and help). | 
| 1749 | + |  | 
| 1750 | + | Fixed bug in genklemsamp that caused non-uniform sampling over surfaces. | 
| 1751 | + |  | 
| 1752 | + | Fixed bugs in rhoptimize and rhcopy for 64-bit compilation. | 
| 1753 | + |  | 
| 1754 | + | Made a change to avoid problem using gcc --fast-math compile option. | 
| 1755 | + |  | 
| 1756 | + | ****** COMPATIBILITY CHANGE ******** | 
| 1757 | + | Changed behavior of rtrace and rtcontrib so that every scanline is | 
| 1758 | + | not flushed when both -x and -y are set.  This avoids flush delays | 
| 1759 | + | in rtcontrib for large numbers of output files and delays while | 
| 1760 | + | rendering images using rtrace with the -n option. | 
| 1761 | + |  | 
| 1762 | + | Added ability for rsensor to output ray origins and directions | 
| 1763 | + | rather than actually loading octree and computing sensor value. | 
| 1764 | + |  | 
| 1765 | + | Fixed old bug in obj2rad where it would stop processing and | 
| 1766 | + | report a syntax error if the "void" type is used in the map file. | 
| 1767 | + |  | 
| 1768 | + | Updated reflection model according to EGSR 2010 paper by David | 
| 1769 | + | Geisler-Moroder and Arne Duer. | 
| 1770 | + |  | 
| 1771 | + | Replaced C-shell version of falsecolor with Perl script written | 
| 1772 | + | by Axel Jacobs. | 
| 1773 | + |  | 
| 1774 | + | ****** COMPATIBILITY CHANGE ******** | 
| 1775 | + | Changed -sj (specular jitter) option to something called specular | 
| 1776 | + | sampling (-ss), which if set less than 1 has the same behavior as | 
| 1777 | + | the old -sj, but when set greater than 1, spawns multiple ray | 
| 1778 | + | samples from semi-specular surfaces. | 
| 1779 | + |  | 
| 1780 | + | Fixed bug noticed by Randolph Fritz that caused ambient sync errors. | 
| 1781 | + |  | 
| 1782 | + | Fixed bug in findglare for reading picture files under Windows. | 
| 1783 | + |  | 
| 1784 | + | Added options to pvalue to note other color spaces on reverse conversion. | 
| 1785 | + | Thanks to Erich Philips for the feature request. | 
| 1786 | + |  | 
| 1787 | + | Added BSDF data-driven material type with full sampling support. | 
| 1788 | + |  | 
| 1789 | + | Added BRDF calculations to genBSDF. | 
| 1790 | + |  | 
| 1791 | + | Bug fixes in rsensor thanks to help from David Geisler-Moroder. | 
| 1792 | + |  | 
| 1793 | + | Added variable-resolution BSDF support in renderers and genBSDF. | 
| 1794 | + |  | 
| 1795 | + | Created pkgBSDF program to extract BSDF geometry and put it | 
| 1796 | + | together with surface description suitable for inclusion in | 
| 1797 | + | a Radiance scene. | 
| 1798 | + |  | 
| 1799 | + | Muted warning for "no light sources found" when there is at least | 
| 1800 | + | one glow object and interreflections are on (-ab > 0). | 
| 1801 | + |  | 
| 1802 | + | Fixed long-standing bug that caused underestimation of reflection | 
| 1803 | + | when specular component was below -st threshold in non-metals. | 
| 1804 | + |  | 
| 1805 | + | Checked in cross-platform cmake build system created by Bill Hoffman | 
| 1806 | + | of KitWare and sponsored by NREL.  This includes a qt-based | 
| 1807 | + | driver for rvu, which is built in the new subdirectory src/qtrvu. | 
| 1808 | + |  | 
| 1809 | + | ===================== | 
| 1810 | + | Version 4.2 (Release date 7/31/2014) | 
| 1811 | + |  | 
| 1812 | + | Axel Jacobs added -cp and -palettes options to falsecolor. | 
| 1813 | + |  | 
| 1814 | + | Fixed bug in matrix output of genBSDF introduced shortly before 4.1 release. | 
| 1815 | + |  | 
| 1816 | + | Made rvu more responsive in multi-processing mode when changing parameters. | 
| 1817 | + | Explicit "new" command not needed to show changes, because it goes back | 
| 1818 | + | to "immediate mode" once something is changed.  Processing will be slow | 
| 1819 | + | but response time quick until next "new" command. | 
| 1820 | + |  | 
| 1821 | + | Fixed major bug in transmitting proxy material sampling. | 
| 1822 | + |  | 
| 1823 | + | Patched cmake build tools (changes by Zack Galbreath). | 
| 1824 | + |  | 
| 1825 | + | Removed requirement for pflip -h to be given input file (can pipe from stdin). | 
| 1826 | + |  | 
| 1827 | + | Added "Number of processes" slider to trad "Action" pane to control rad -N | 
| 1828 | + | option for rvu and batch rendering. | 
| 1829 | + |  | 
| 1830 | + | Added -c option to vwrays to repeat pixels for rtcontrib. | 
| 1831 | + |  | 
| 1832 | + | Reworked rtcontrib program and renamed to rcontrib.  New version runs much | 
| 1833 | + | faster, especially on multiprocessor systems, and doesn't require as much | 
| 1834 | + | memory.  No longer calls rtrace; instead does all the work itself. | 
| 1835 | + |  | 
| 1836 | + | Added -d option to genskyvec to produce direct-only (sun no sky) vector. | 
| 1837 | + |  | 
| 1838 | + | Added Ashikhmin-Shirley anisotropic BRDF model (ashik2) with help | 
| 1839 | + | from Nicolas Boneel. | 
| 1840 | + |  | 
| 1841 | + | Added Ruby rewrite of objview.csh by Rob Guglielmetti. | 
| 1842 | + |  | 
| 1843 | + | Fixed bug in reciprocity for tensor tree BTDF representations.  Thanks | 
| 1844 | + | to Andy McNeil for identifying the problem. | 
| 1845 | + |  | 
| 1846 | + | Added MNAME and ZNAME variables to ranimove for debugging & testing. | 
| 1847 | + |  | 
| 1848 | + | Created pmblur2 command to take motion and depth buffers from ranimove | 
| 1849 | + | to compute a better motion blur. | 
| 1850 | + |  | 
| 1851 | + | ****** COMPATIBILITY CHANGE ******** | 
| 1852 | + | Changed BSDF routines to use updated/corrected XML specification and | 
| 1853 | + | removed depracated BSDF support from mkillum. | 
| 1854 | + |  | 
| 1855 | + | Fixed behavior of i/o flushing in rcontrib with -c > 1 (averaging).  Thanks | 
| 1856 | + | to Lars Grobe for help identifying this problem. | 
| 1857 | + |  | 
| 1858 | + | Fixed bug in depth-of-field blur where view distance was measured from | 
| 1859 | + | fore clipping plane rather than viewpoint.  Thanks to Peter A-B for | 
| 1860 | + | pointing this out. | 
| 1861 | + |  | 
| 1862 | + | Added options to dctimestep to allow multiple time steps (-n) | 
| 1863 | + | and multiple output pictures or sensor files (-o).  Also added -i | 
| 1864 | + | option to specify float (-if) or double (-id) input for sky matrix. | 
| 1865 | + |  | 
| 1866 | + | Created gendaymtx program to compute annual sky patch matrix based | 
| 1867 | + | on Ian Ashdown's implementation of Perez all-weather sky model. | 
| 1868 | + | Output can be sent directly to dctimestep in ASCII or binary stream. | 
| 1869 | + |  | 
| 1870 | + | Replaced existing gendaylit.c with improved version from Wendelin Sprenger | 
| 1871 | + | and Jan Wienold of ISE. | 
| 1872 | + |  | 
| 1873 | + | Improved accuracy of ambient calculation for large -ad settings.  Thanks | 
| 1874 | + | to Lars Grobe for noticing the problem. | 
| 1875 | + |  | 
| 1876 | + | Added -r option to gendaymtx to rotate the sky the specified number of | 
| 1877 | + | degrees about the zenith as suggested by A. McNeil. | 
| 1878 | + |  | 
| 1879 | + | Axel Jacobs added -pal eco color map that does a blue-red-yellow scale. | 
| 1880 | + |  | 
| 1881 | + | Created bsdf2klems tool to convert from various BSDF representations to | 
| 1882 | + | Klems basis matrix in XML file. | 
| 1883 | + |  | 
| 1884 | + | Fixed problem with inappropriate reciprocity enforcement on tensor | 
| 1885 | + | tree reduction in genBSDF.  (Thanks to A.McNeil for discovering issue.) | 
| 1886 | + |  | 
| 1887 | + | Fixed bug in isotropic tensor tree sampling for impinging rays | 
| 1888 | + | exactly normal to surface.  Thanks to Peter Apian-Bennewitz for | 
| 1889 | + | discovering and pointing out the error. | 
| 1890 | + |  | 
| 1891 | + | Fixed double-counting bug in mirror material with alternate type. | 
| 1892 | + | Thanks to David Geisler-Moroder for spotting the problem and helping | 
| 1893 | + | to fix it. | 
| 1894 | + |  | 
| 1895 | + | Created rcollate program to resize and transpose matrix data for Andy | 
| 1896 | + | McNeil's 5-phase annual simulation method. | 
| 1897 | + |  | 
| 1898 | + | Added epw2wea conversion program by Christoph Reinhart. | 
| 1899 | + |  | 
| 1900 | + | Implemented Perlin's improved noise function with help from Rahul Narain. | 
| 1901 | + | This will change the appearance of renderings using this function. | 
| 1902 | + |  | 
| 1903 | + | Added "origin" command to rvu as requested by John Mardaljevic | 
| 1904 | + | to place view origin at selected point in scene. | 
| 1905 | + |  | 
| 1906 | + | Switch to Perl versions of objview and objpict written by Axel Jacobs. | 
| 1907 | + |  | 
| 1908 | + | Improved rendering speed of scenes with aliases by not entering new | 
| 1909 | + | modifiers into table if they are the same as the previously defined | 
| 1910 | + | modifier for that name. | 
| 1911 | + |  | 
| 1912 | + | Made it so icalc and rcalc search RAYPATH directories for *.cal files | 
| 1913 | + | given on command line.  This simplifies script writing and makes these | 
| 1914 | + | utilities consistent with other tools in Radiance. | 
| 1915 | + |  | 
| 1916 | + | Added triangulation routine to handle convex polygons in obj2mesh. | 
| 1917 | + |  | 
| 1918 | + | ****** COMPATIBILITY CHANGE ******** | 
| 1919 | + | Made backface visibility apply to all material types, including | 
| 1920 | + | transparent and translucent materials (except dielectric and interface). | 
| 1921 | + | This makes the option useful in cases where adjacent trans surfaces | 
| 1922 | + | are placed next to each other by a modeler that only understands | 
| 1923 | + | volumetric objects. | 
| 1924 | + |  | 
| 1925 | + | Changed dctimestep so that output matrices (-n > 1) are preceded by a | 
| 1926 | + | header, and added support for float and double output formats with -o[fd]. | 
| 1927 | + |  | 
| 1928 | + | Introduced eplus_adduvf program to compute user view factors for EnergyPlus. | 
| 1929 | + |  | 
| 1930 | + | Changed image-plane sampling in rpict to use Hilbert curve, which gives | 
| 1931 | + | less of a brushed/striped appearance to output pixels with -u- (default). | 
| 1932 | + |  | 
| 1933 | + | Added ltview and ltpict Perl scripts contributed by Axel Jacobs, inspired | 
| 1934 | + | by Rob Guglielmetti. | 
| 1935 | + |  | 
| 1936 | + | Added header variables for NROWS, NCOLS and NCOMP to help standardize | 
| 1937 | + | matrix files.  This functionality has been incorporated into | 
| 1938 | + | rcollate, gendaymtx, and dctimestep. | 
| 1939 | + |  | 
| 1940 | + | Created rmtxop utility to operate on multi-component matrices.  This | 
| 1941 | + | facilitates some daylight matrix calculations, and provides a general | 
| 1942 | + | tool for manipulating matrix data. | 
| 1943 | + |  | 
| 1944 | + | ****** COMPATIBILITY CHANGE ******** | 
| 1945 | + | Introduced new Hessian-based error control in irradiance caching (ambient) | 
| 1946 | + | calculation.  Since the format of the stored ambient values is different, | 
| 1947 | + | the old files will be rejected with an error message and must be removed. | 
| 1948 | + | The programs may be compiled with the -DOLDAMB option if this is a problem. | 
| 1949 | + |  | 
| 1950 | + | Added -p option to rcontrib to set function file parameters on a per-modifier | 
| 1951 | + | basis to simplify bin evaluation. | 
| 1952 | + |  | 
| 1953 | + | Created rfluxmtx program to compute flux transfer matrices from a sender | 
| 1954 | + | surface to one or more receiver surfaces.  (Renamed the file klems_int.cal | 
| 1955 | + | to klems_full.cal in the process.) | 
| 1956 | + |  | 
| 1957 | + | Added "-c" option to getinfo to execute command on data segment. | 
| 1958 | + |  | 
| 1959 | + | ================================ | 
| 1960 | + | Version 5.0 (Released 9/18/2015) | 
| 1961 | + |  | 
| 1962 | + | Changed rmtxop so it writes out same type as lesser of inputs unless | 
| 1963 | + | directed otherwise using -f? option. | 
| 1964 | + |  | 
| 1965 | + | Changed order of oconv arguments in rfluxmtx so user can specify input | 
| 1966 | + | octree using -i option at the end instead of (or in addition to) a | 
| 1967 | + | list of scene files. | 
| 1968 | + |  | 
| 1969 | + | Added support for argument expansion to rfluxmtx and bug fixes. | 
| 1970 | + |  | 
| 1971 | + | Fixed bug in indirect hemisphere sampling for some corner cases. | 
| 1972 | + |  | 
| 1973 | + | Added default specular lobe to BSDF interpolation. | 
| 1974 | + |  | 
| 1975 | + | Set minimum number of shadow checks before direct optimization (4). | 
| 1976 | + |  | 
| 1977 | + | (Above changes included in 4.2.1 patch release.) | 
| 1978 | + |  | 
| 1979 | + | ****** COMPATIBILITY CHANGE ******** | 
| 1980 | + | Made header input and output the default behavior for dctimestep and | 
| 1981 | + | genskyvec. | 
| 1982 | + |  | 
| 1983 | + | ****** COMPATIBILITY CHANGE ******** | 
| 1984 | + | Changed pabopto2bsdf default behavior to add 90-degree rotation | 
| 1985 | + | to bring pgII's definition of "up" in line with Klems axis | 
| 1986 | + | conventions.  Introduced a new header variable "upphi" to | 
| 1987 | + | control this added rotation.  Using "#upphi 90" in each | 
| 1988 | + | BSDF input file gets back the original behavior, where it | 
| 1989 | + | assumes that the up direction is 90-degrees from the X-axis. | 
| 1990 | + | The default value of 0 corresponds to PAB's definition of | 
| 1991 | + | the X-axis as being "up". | 
| 1992 | + |  | 
| 1993 | + | Fixed bug in rsensor related to having many rows (altitude) and | 
| 1994 | + | few columns (azimuth) in sensitivity file. | 
| 1995 | + |  | 
| 1996 | + | Fixed floating point round-off error in new Hessian calculation | 
| 1997 | + | for some sytems (Windows, primarily). | 
| 1998 | + |  | 
| 1999 | + | Fixed bug in tensor tree BSDF code that caused bus error on | 
| 2000 | + | some systems, and may have been source of other errors as well. | 
| 2001 | + |  | 
| 2002 | + | (Above changes included in 4.2.2 patch release.) | 
| 2003 | + |  | 
| 2004 | + | Improved ambient extrapolation to avoid zero values.  Actual | 
| 2005 | + | threshold set to 5% of recorded value. | 
| 2006 | + |  | 
| 2007 | + | Changed anisotropic Gaussian and Ashikhmin models so that | 
| 2008 | + | illegal orientation vectors are dealt with more gracefully. | 
| 2009 | + |  | 
| 2010 | + | Created wrapBSDF tool and incorporated into genBSDF along | 
| 2011 | + | with new rfluxmtx computation. | 
| 2012 | + |  | 
| 2013 | + | Initial check-in of Roland Schregle's photon map integration. | 
| 2014 | + | New 5.0a version designation as suggested by Andy McNeil. | 
| 2015 | + |  | 
| 2016 | + | Added left-hand coordinate sytems to rfluxmtx to correct | 
| 2017 | + | problems with coordinate axis orientations pointed out by | 
| 2018 | + | David Geisler-Moroder. | 
| 2019 | + |  | 
| 2020 | + | Added color output to genBSDF (+C option) and support for | 
| 2021 | + | color rendering of Klems and tensor tree data. | 
| 2022 | + |  | 
| 2023 | + | Fixed another bug in rsensor that caused rays to be generated | 
| 2024 | + | on opposite side of hemisphere even where sensitivity was zero. | 
| 2025 | + |  | 
| 2026 | + | Fixed bug discovered by Jacob Jonsson in Klems BSDF | 
| 2027 | + | interpolator that caused it to over-predict normal | 
| 2028 | + | transmittance and reflectance. | 
| 2029 | + |  | 
| 2030 | + | Added ability to read input from commands in dctimestep | 
| 2031 | + | and rmtxop. | 
| 2032 | + |  | 
| 2033 | + | Added photon map support to rad.  Fixed some double-counting | 
| 2034 | + | issues in photon-mapping spotted by David Geisler-Moroder. | 
| 2035 | + |  | 
| 2036 | + | Added photon map support to trad. | 
| 2037 | + |  | 
| 2038 | + | Fixed bug in antimatter source testing when antimatter | 
| 2039 | + | definition follows potential obstructor in input. | 
| 2040 | + |  | 
| 2041 | + | Fixed issue with missing character type identifier at head | 
| 2042 | + | of genBSDF XML output. | 
| 2043 | + |  | 
| 2044 | + | Prompted by Roland S., added option to have pcompos -a order | 
| 2045 | + | rows from top rather than bottom of image. | 
| 2046 | + |  | 
| 2047 | + | Changed dctimestep to accept matrix as well as BTDF input | 
| 2048 | + | in the VTDs invocation mode.  This permits the output of | 
| 2049 | + | rmtxop to be used in a pinch when combining multiple BTDF | 
| 2050 | + | layers, although interreflection between layers is not | 
| 2051 | + | accounted for properly as it is in the WINDOW program. | 
| 2052 | + |  | 
| 2053 | + | Added Jan Wienold et al.'s evalglare to distribution. | 
| 2054 | + |  | 
| 2055 | + | Hopeful fix to deadlock issue under Mac OS X 10.10.x (Yosemite). | 
| 2056 | + |  | 
| 2057 | + | Fixed early exit of rcontrib with internal error (sample behind sender) | 
| 2058 | + | discovered by Rob G. | 
| 2059 | + |  | 
| 2060 | + | ================================= | 
| 2061 | + | Version 5.1 (Released 8/17/2017) | 
| 2062 | + |  | 
| 2063 | + | Fixed issue with vchars.mta and symbols.mta not being installed in | 
| 2064 | + | the appropriate metafile library location, with help from Rob G. | 
| 2065 | + |  | 
| 2066 | + | Added ability to give quoted strings to output= directive in rfluxmtx. | 
| 2067 | + |  | 
| 2068 | + | ****** COMPATIBILITY CHANGE ******** | 
| 2069 | + | Added ability to digest color (CIE-XYZ) input in pabopto2bsdf. | 
| 2070 | + | This change alters the .sir (interpolant) format, so these files | 
| 2071 | + | will need to be regenerated.  Use the new "#colorimetry: CIE-XYZ" tag | 
| 2072 | + | to enable on input. | 
| 2073 | + |  | 
| 2074 | + | Rewrote bsdf2klems to support tristimulus color and call wrapBSDF. | 
| 2075 | + | Did the same for bsdf2ttree.  Function specifications still gray only. | 
| 2076 | + |  | 
| 2077 | + | Reduced a problem where rvu or rholo would be slow to quit when | 
| 2078 | + | run with many processes on a large model or one with a large | 
| 2079 | + | ambient file (taking lots of memory).  We were waiting for | 
| 2080 | + | processes to quit one-by-one, which takes some time for each | 
| 2081 | + | process as it disentangles its shared memory.  We now | 
| 2082 | + | wait for all the processes together, so they can disentangle | 
| 2083 | + | in parallel.  It can still take up to a minute in some cases, | 
| 2084 | + | but not 10 minutes like it was taking before the fix. | 
| 2085 | + |  | 
| 2086 | + | Enabled ambient cache value corral for all levels, not just final two. | 
| 2087 | + | This may reduce errors in certain pathological scenes. | 
| 2088 | + |  | 
| 2089 | + | Added -in option to rcalc, rlam, and total to limit the number of | 
| 2090 | + | input records in hopes of circumventing Windows EOF issues on binary data. | 
| 2091 | + | Also added -on option to rcalc and total for logical symmetry. | 
| 2092 | + |  | 
| 2093 | + | Increased modifier limit to 10,000 in rcontrib. | 
| 2094 | + |  | 
| 2095 | + | Fixed issues with glrad and added zoom response to mouse wheel input. | 
| 2096 | + |  | 
| 2097 | + | Added missing definition of "ashik2" material type to reference manual. | 
| 2098 | + |  | 
| 2099 | + | Changed genBSDF to calculate device thickness assuming Zmax==0 so | 
| 2100 | + | pkgBSDF will generate correct proxy geometry. | 
| 2101 | + |  | 
| 2102 | + | Created pabopto2xyz tool to combine different sensor measurements | 
| 2103 | + | into a single CIE-XYZ measurement file for color BSDF interpolation. | 
| 2104 | + |  | 
| 2105 | + | Jan Wienold updated evalglare to version 1.30 | 
| 2106 | + |  | 
| 2107 | + | Roland Schregle added out-of-core photon mapping routines, which | 
| 2108 | + | may be compiled using the PMAP_OOC macro. | 
| 2109 | + |  | 
| 2110 | + | Added -a option to getinfo for easy addition of header lines. | 
| 2111 | + |  | 
| 2112 | + | Fixed issue with multiple records on picture output in rcontrib (and rfluxmtx). | 
| 2113 | + | Credit to Sarith Subramaniam for pointing out the problem. | 
| 2114 | + |  | 
| 2115 | + | Made mkillum more tolerant of non-planar polygons in its sampling routines. | 
| 2116 | + |  | 
| 2117 | + | Added "-recover" option to genBSDF to pick up where it left off. | 
| 2118 | + |  | 
| 2119 | + | Fixed genBSDF issue that was created incorrect normalization of | 
| 2120 | + | Klems output.  Thanks to David G-M and Christian Knoflach for | 
| 2121 | + | discovering the error.  Also improved sampling of indirect irradiance | 
| 2122 | + | that showed some slight bias due to poor sample collision avoidance. | 
| 2123 | + |  | 
| 2124 | + | Fixed long-standing issue with -aa 0 neglecting textures in calculating | 
| 2125 | + | surface shading. | 
| 2126 | + |  | 
| 2127 | + | Fixed bug in ranimove introduced during photon map integration. | 
| 2128 | + |  | 
| 2129 | + | Added check for steep sections of BSDF in pabopto2bsdf, creating narrower | 
| 2130 | + | peakes in those places and mitigating some normalization issues. | 
| 2131 | + |  | 
| 2132 | + | Added view360stereo.cal by Mark Stock to handle 360-degree over/under | 
| 2133 | + | stereo views. | 
| 2134 | + |  | 
| 2135 | + | Added MAX2SHADE macro to place limit on number of light sources | 
| 2136 | + | to precheck for obstructions.  (Currently set to 200.)  This | 
| 2137 | + | avoids excessive start-up times for scenes with many light sources. | 
| 2138 | + | Thanks to Axel Jacobs for pointing out the problem. | 
| 2139 | + |  | 
| 2140 | + | Added -v option to obj2mesh to print out mesh statistics. | 
| 2141 | + |  | 
| 2142 | + | Rewrote bsdf2rad from ground up and made it a standard part of build. | 
| 2143 | + |  | 
| 2144 | + | Fixed bug in orientation of Reinhart/Tregenza sample generator in rfluxmtx. | 
| 2145 | + |  | 
| 2146 | + | Added ability to perform shadow-testing through unproxied BSDFs with strong | 
| 2147 | + | through (direct-direct) component. | 
| 2148 | + |  | 
| 2149 | + | Added {+|-}a options to genBSDF and bsdf2ttree for switching off reciprocity | 
| 2150 | + | averaging. | 
| 2151 | + |  | 
| 2152 | + | Added bias to see through BTDFs with a strong "through" component | 
| 2153 | + | rather than scattering view rays.  This is in lieu of peak extraction, | 
| 2154 | + | which looked to be too difficult from an implementation standpoint. | 
| 2155 | + |  | 
| 2156 | + | Added bsdfview tool analogous to objview but for BSDF files (XML and SIR), | 
| 2157 | + | which calls bsdf2rad then rad with a few useful default views. | 
| 2158 | + |  | 
| 2159 | + | ========================= | 
| 2160 | + | Version 5.2 | 
| 2161 | + |  | 
| 2162 | + | Created psketch program to apply non-photorealistic rendering to selected | 
| 2163 | + | objects, identified by modifier name(s). | 
| 2164 | + |  | 
| 2165 | + | Added '*' and '/' operations to rmtxop for element-wise multiplication and | 
| 2166 | + | division of same-sized matrices. | 
| 2167 | + |  | 
| 2168 | + | Changed falsecolor so "-s" option is adjusted to match legend if one. | 
| 2169 | + |  | 
| 2170 | + | Falsecolor legend changes and improvements by David G-M and Stephen W. | 
| 2171 | + |  | 
| 2172 | + | Fixed bug in peak extraction code that generated | 
| 2173 | + | "Bad call to SDqueryTreProjSA" error, reported by Lars Grobe. | 
| 2174 | + |  | 
| 2175 | + | Increased maximum luminance to 10^7 in pcond to fix issue noticed | 
| 2176 | + | by Axel Jacobs where veiling glare not added for the sun under | 
| 2177 | + | some conditions. | 
| 2178 | + |  | 
| 2179 | + | Increased maximum number of open files in rcontrib to the system upper | 
| 2180 | + | limit of 2048 rather than the default 512 under Windows. | 
| 2181 | + |  | 
| 2182 | + | Added top-level resources directory with files from Rob Guglielmetti. | 
| 2183 | + |  | 
| 2184 | + | Improved accuracy for peaky BSDFs and small light sources. | 
| 2185 | + |  | 
| 2186 | + | Fixed issue with pmapdump noted by Axel Jacobs. | 
| 2187 | + |  | 
| 2188 | + | Improved accuracy of bsdf2ttree when converting scattering interpolation | 
| 2189 | + | representatons with strong peaks. | 
| 2190 | + |  | 
| 2191 | + | Tweaked peak-extraction code to work more reliably. | 
| 2192 | + |  | 
| 2193 | + | Georg Mischler updated SCons build system. | 
| 2194 | + |  | 
| 2195 | + | Rob Guglielmetti and Alex Swindler updated CMake build system. | 
| 2196 | + |  | 
| 2197 | + | Modified pcomb so the first view seen in the inputs is written into header. | 
| 2198 | + |  | 
| 2199 | + | Wrote rtpict script to run rtrace in parallel mode and simulate rpict with | 
| 2200 | + | -n option. | 
| 2201 | + |  | 
| 2202 | + | Added ability to move forwards/backwards specified distance in rvu "origin" | 
| 2203 | + | command.  Feature requested by John Mardaljevic, who essentially owns this | 
| 2204 | + | command, now. | 
| 2205 | + |  | 
| 2206 | + | Reduced bias in ambient super-sampling method. | 
| 2207 | + |  | 
| 2208 | + | Fixed bugs associated with zero transmission in chromatic tensor trees. | 
| 2209 | + | Thanks to Lars Grobe for pointing out issues. | 
| 2210 | + |  | 
| 2211 | + | Added RAYPATH searching for -f options to genrev, gensurf, genworm, | 
| 2212 | + | bsdf2klems, bsdf2ttree, and pcomb.  This makes behavior consistent | 
| 2213 | + | with rcalc, calc, and rendering tools. |
