Output flushing at fixed intervals may be enabled with the |
| 125 |
+ |
.I \-x |
| 126 |
+ |
option, which specifies the number of records |
| 127 |

(-c accumulations) before each flush. |
| 128 |

If the |
| 129 |
+ |
.I \-y |
| 130 |

option is also set, then periodic flushing is disabled and the |
| 131 |

output size for an RGB image is the taken from the x and y dimensions. |
| 132 |

In lieu of periodic flushing, a flush may be forced as mentioned above |
| 133 |
+ |
by sending a sample with a zero direction vector, although you |
| 134 |
+ |
must still send a full record of rays before output occurs. |

If progress reports are desired, the |

.I \-t |

option specifies a time interval in seconds for reports sent to |

standard error. |
| 140 |

This requires that the number of input samples is known, meaning a |
