options are not supported, and |
| 62 |
|
.I \-pe |

|
.PP |
| 65 |

The |
| 66 |

.I \-n |
| 67 |

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 |

.TP |
| 170 |
|
.BI frame " [ xmin ymin xmax ymax ]" |
| 171 |
|
Set frame for refinement. |
| 226 |
|
The default factor is one. |
| 227 |
|
Care must be taken to avoid moving behind or inside other objects. |
| 228 |
|
.TP |

.BR new |

.BI new " [ nproc ]" |

Restart the image, using the specified number of rendering processes. |
| 231 |
|
Usually used after the "set" command. |
| 232 |
|
.TP |
| 233 |
+ |
.BI origin " [ xo yo zo [ xd yd zd ] ]" |
| 234 |
+ |
Change view origin to the indicated world position |
| 235 |
+ |
.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. |
| 244 |
+ |
.TP |
| 245 |
|
.BI pivot " angle [ elev [ mag [ x y z ] ] ]" |
| 246 |
|
Similar to the "move" command, but pivots the view about a selected point. |
| 247 |
|
The |
| 248 |
|
.I angle |
| 249 |
< |
is measured in degrees around the view up vector using the right hand rule. |
| 249 |
> |
is measured in degrees around the view up vector using the right hand rule, |
| 250 |
> |
so a positive value pivots the viewer to the right of the selected point. |
| 251 |
|
The optional |
| 252 |
|
.I elev |
| 253 |
|
is the elevation in degrees from the pivot point; positive raises the view point |
| 266 |
|
.BI rotate " angle [ elev [ mag ] ]" |
| 267 |
|
Rotate the camera horizontally by |
| 268 |
|
.I angle |
| 269 |
< |
degrees. |
| 269 |
> |
degrees using the right-hand rule. |
| 270 |
> |
A positive value rotates the view towards the left, and a negative value |
| 271 |
> |
looks to the right. |
| 272 |
|
If an elevation is specified, the camera looks upward |
| 273 |
|
.I elev |
| 274 |
|
degrees. |

The screen will be redrawn when the program resumes. |
