everything now gets linked to -lrtrad instead of -lrt. |

Fixed problem with large sample sets, so -u+ option now is truly random. |

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, |

especially on machines with slow log() calls. The first call to |

tmCvLums(), tmCvGrays(), or tmCvColors() initializes the table. |

1585 |

Created optics2rad.csh script to convert from Optics 5 material output |

a Radiance scene. |
1798 |

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 |

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. |

===================== |
1810 |

Version 4.2 |
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 |

****** 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-to-yellow range. |
