Fixed bug that caused incorrect reporting of non-surface in set when |
| 1383 |
|
mixing meshes and instances. (Thanks to Jack de Valpine for discovery.) |

Fixed inaccuracy in calculation of diffuse transmission in the presence |

of pure specular (Fresnel reflection) using "trans" material. Thanks |

Added rtcontrib -r option to recover partial output. |
| 1473 |

|
| 1474 |

Added -u rendering option for pure Monte Carlo sampling. |
| 1475 |
+ |
(Got rid of -DMC compile option, which this makes superfluous.) |
| 1476 |
+ |
|
| 1477 |

Changed -t option of rlam to accept strings as well as single characters. |
| 1478 |
+ |
|
| 1479 |

Fixed bug in rcalc with -l option where it would sometimes go into an |
| 1480 |
+ |
infinite loop. |
| 1481 |

Fixed truly ancient bug in bounding box computation for cones, which |
| 1483 |
+ |
could (and did) cause missing segments. |

Added -z option to normtiff to output LZW-compressed files. |

Last change to total causes it to produce results when it sees an empty |
| 1488 |
+ |
line on the input. This was not intentional, but I decided I like this |
| 1489 |
+ |
behavior so I documented it rather than changing it. |

===================== |

Version 3.8 |
| 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 |
| 1496 |
+ |
minimum ray sampling weight (serious). |
| 1497 |
+ |
|
| 1498 |
+ |
Changed mksource to use 98th percentile (rather than 99th) for threshold. |
| 1499 |
+ |
|
| 1500 |
+ |
(Above changes included in 3.7.1 patch release.) |
| 1501 |
+ |
|
| 1502 |
+ |
Eliminated writing of EXPOSURE= line in ra_tiff -r when source TIFF |
| 1503 |
+ |
does not have STONITS set. |
| 1504 |
+ |
|
| 1505 |
+ |
Fixed bug in ambient calculation that caused black values for multiple |
| 1506 |
+ |
bounces in some scenes. Thanks to Mark Stock for creating and sharing |
| 1507 |
+ |
the sophisticated test scene that demonstrated this problem. |
| 1508 |
+ |
|
| 1509 |
+ |
Fixed bug in antimatter using Russian Roulette sampling. |
