Fixed bug that caused incorrect reporting of non-surface in set when |

mixing meshes and instances. (Thanks to Jack de Valpine for discovery.) |

Implemented Russian roulette ray termination with -lr set to 0. Made |

Made it so -o option of rtcontrib can pipe -o output to a command. |

Added -if and -of options to total for binary i/o (following rcalc mold). |

Switched default options in rtrace to use Russian roulette. (Rpict and rvu |

Version 3.8 |

|
| 1494 |

Fixed Russian roulette ray termination, which was doing the opposite of |
| 1495 |

what it should have been doing, resulting in overestimated values below |
| 1496 |

minimum ray sampling weight (serious). |
| 1497 |

|
| 1498 |

Changed mksource to use 98th percentile (rather than 99th) for threshold. |

(Above changes included in 3.7.1 patch release.) |

Eliminated writing of EXPOSURE= line in ra_tiff -r when source TIFF |

does not have STONITS set. |

Fixed bug in ambient calculation that caused black values for multiple |

bounces in some scenes. Thanks to Mark Stock for creating and sharing |
| 1507 |

the sophisticated test scene that demonstrated this problem. |

Created fieldcomb script to combine alternate fields in a rendering |
| 1514 |

sequence. (Development generously sponsored by Iebele Abel.) |
| 1515 |

|
| 1516 |

Added missing preload of mesh objects for more efficient memory use |
| 1517 |

during parallel rendering -- this was a serious oversight. |

Created ran2tiff program to automate exposure setting of animation |
| 1520 |

sequences using a moving histogram in combination with pcond, and |
| 1521 |

converting frames to TIFF. |

Eliminated SPEED macro from makeall and source tree. |

Added -pj option to vwrays to allow jittering of sample locations. |
| 1526 |

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.) |

Rearranged struct's for better efficiency on 64-bit architectures. |

Added -i option to rlam so it works with binary input formats. |

Added rtcontrib -bn option to specify number of bins and fixed bug |

in recovery of files containing multiple values per record. |

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. |
