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. |

.BI frame " [ xmin ymin xmax ymax ]" |

Set frame for refinement. |

The default factor is one. |

Care must be taken to avoid moving behind or inside other objects. |

Restart the image, using the specified number of rendering processes. |

Usually used after the "set" command. |

.BI origin " [ xo yo zo [ xd yd zd ] ]" |

.I "xo yo zo" |
| 236 |

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. |

.TP |
