.TP |

.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 |

< |
.BI origin " [ xo yo zo [ xd yd zd ] ]" |
| 236 |
< |
Change view origin to the indicated world position |
| 237 |
< |
.I "xo yo zo" |
| 238 |
< |
looking in the direction |
| 239 |
< |
.I "xd yd zd." |
| 240 |

If the direction is missing, the current view direction is used. |
| 241 |
< |
If the origin is missing, the cursor is used to select the |
| 235 |

.BI origin " [ forward [ right [up] ] ]" |
| 236 |

Move the view origin forward or backwards the distance specified by the |
| 237 |

.I forward |
| 238 |

argument, along the view direction vector. |
| 239 |
> |
If at least two arguments are given, the second distance will be a |
| 240 |
> |
.I right |
| 241 |

shift, or left if negative relative to the current view direction. |
| 242 |
> |
If three arguments are given, the third distance will be a distance of |
| 243 |
> |
.I up |
| 244 |

along the view up vector, or down if negative. |
| 245 |

The view direction and size are unchanged in any of the above cases. |
| 246 |

With no arguments, the cursor is used to select the |
| 247 |
|
view origin, and the direction will be determined by the |
| 248 |
|
(reoriented) surface normal. |
| 249 |
|
The view type and size will not be altered, but the up vector |
| 253 |
|
Similar to the "move" command, but pivots the view about a selected point. |
| 254 |
|
The |
| 255 |
|
.I angle |
| 256 |
< |
is measured in degrees around the view up vector using the right hand rule. |
| 256 |
> |
is measured in degrees around the view up vector using the right hand rule, |
| 257 |
> |
so a positive value pivots the viewer to the right of the selected point. |
| 258 |
|
The optional |
| 259 |
|
.I elev |
| 260 |
|
is the elevation in degrees from the pivot point; positive raises the view point |
| 273 |
|
.BI rotate " angle [ elev [ mag ] ]" |
| 274 |
|
Rotate the camera horizontally by |
| 275 |
|
.I angle |
| 276 |
< |
degrees. |
| 276 |
> |
degrees using the right-hand rule. |
| 277 |
> |
A positive value rotates the view towards the left, and a negative value |
| 278 |
> |
looks to the right. |
| 279 |
|
If an elevation is specified, the camera looks upward |
| 280 |
|
.I elev |
| 281 |
|
degrees. |
