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

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

|
(The focus distance setting does not affect rendering in |

< |
.I rview, |

but can be used in |

|
.I rpict |
| 165 |
|
with the |
| 166 |
|
.I \-pd |
| 167 |
|
option to simulate depth-of-field on views saved from |
| 168 |
< |
.I rview.) |
