Improved -f option of normpat, which caused odd color changes before. |
| 1244 |

Created pgblur script which does fast Gaussian blur of image without changing |

****** COMPATIBILITY CHANGE ******** |

Changed little-used objpict script so that it takes scene files rather than |

rpict options on the command line, and puts everything into the right |

coordinate position automatically rather than requiring the user to do it. |

Rob Guglielmetti added -lw and -lh options to falsecolor to control the |

It's the most horrible image format I've ever seen, and I've seen a lot. |

Increased -aa default value for all renderers (and also -ad and -as in |

|
| 1272 |

Modified oconv to keep subdividing the octree if there are too many |
| 1273 |
> |
objects in a voxel even when the -r resolution limit has been |

If that isn't enough, then there's probably no hope, anyway. |

Increased polygon vertex limit to 512 in obj2mesh and obj2rad and added |

warning if this limit is exceeded. |

|
| 1284 |

Added tone-mapping and monitor primary options to ra_bmp. This gives |

Fixed a very obscure bug in rpict that caused a dark horizontal |

Fixed problems with effective ray lengths computed for dielectric |

Changed ambient calculation so that -ad will not limit recursion |

Rearranged the way ray contributions are computed so that it might be |

possible to use rtrace to derive daylight coefficients and optical |

contribution weights for each ray, which combined with the -ti (or -tI) |
| 1430 |
> |
option permits the contribution of selected surfaces or sources to |
| 1431 |

be determined. Using the -oTW option, one should also specify |

options "-dt 0 -aa 0 -as 0" for optimal results. In particular, |

caching on (-aa > 0). |

|
| 1436 |

The same code modifications included a change to the indirect computation |
