.BI move " [ mag [ x y z ] ]" |
| 215 |
|
Move camera |
| 232 |
|
Restart the image, using the specified number of rendering processes. |
| 233 |
|
Usually used after the "set" command. |
| 234 |
|
.TP |

Change view origin to the indicated world position |
| 235 |

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

Move the view forward or backwards the distance specified by a single |

argument along the view direction vector. |

.I "xo yo zo" |

looking in the direction |

.I "xd yd zd." |

If the direction is missing, the current view direction is used. |

If the origin is missing, the cursor is used to select the |

If the direction is unspecified, the current view direction is used. |
| 245 |

Without arguments, the cursor is used to select the |
| 246 |
|
view origin, and the direction will be determined by the |
| 247 |
|
(reoriented) surface normal. |
| 248 |
|
The view type and size will not be altered, but the up vector |
| 252 |
|
Similar to the "move" command, but pivots the view about a selected point. |
| 253 |
|
The |
| 254 |
|
.I angle |
| 255 |
< |
is measured in degrees around the view up vector using the right hand rule. |
| 255 |
> |
is measured in degrees around the view up vector using the right hand rule, |
| 256 |

so a positive value pivots the viewer to the right of the selected point. |
| 257 |
|
The optional |
| 258 |
|
.I elev |
| 259 |
|
is the elevation in degrees from the pivot point; positive raises the view point |
| 272 |
|
.BI rotate " angle [ elev [ mag ] ]" |
| 273 |
|
Rotate the camera horizontally by |
| 274 |
|
.I angle |
| 275 |
< |
degrees. |
| 275 |
> |
degrees using the right-hand rule. |
| 276 |
> |
A positive value rotates the view towards the left, and a negative value |
| 277 |

looks to the right. |
| 278 |
|
If an elevation is specified, the camera looks upward |
| 279 |
|
.I elev |
