.BI focus " [distance]" |
151 |

Set focus distance for depth-of-field sampling. |

If a distance in world coordinates is absent, then the cursor |
153 |

is used to choose a point in the scene on which to focus. |

(The focus distance setting does not affect rendering in |

but can be used in |

.I rpict |

Once a variable has been changed, the "new" command can be used |
