.BI focus " [distance]" |
| 151 |
+ |
Set focus distance for depth-of-field sampling. |
| 152 |

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 |

to recompute the image with the new parameters. |
