.BI focus " [distance]" |
| 158 |
+ |
Set focus distance for depth-of-field sampling. |
| 159 |
+ |
If a distance in world coordinates is absent, then the cursor |
| 160 |
+ |
is used to choose a point in the scene on which to focus. |
| 161 |

(The focus distance setting does not affect rendering in |

.I "xo yo zo" |

looking in the direction |
| 237 |
+ |
.I "xd yd zd." |
| 238 |

If the direction is missing, the current view direction is used. |
| 239 |
+ |
If the origin is missing, the cursor is used to select the |
| 240 |
+ |
view origin, and the direction will be determined by the |
| 241 |
+ |
(reoriented) surface normal. |
| 242 |
+ |
The view type and size will not be altered, but the up vector |
| 243 |

may be changed if the new direction coincides. |
