Normally, the transfer command does something such as convert the |
| 272 |
|
frames to another format and/or copy them to tape or some other |
| 273 |
|
destination device before removing them. |
| 274 |
+ |
The |
| 275 |
+ |
.I fieldcomb(1) |
| 276 |
+ |
script may be used to conveniently combine fields into frames for |
| 277 |
+ |
field-based animations. |
| 278 |
|
If this variable is not given, the final frames are left where they |
| 279 |
|
are. |

The command to use instead of |
| 286 |
< |
.I rsh(1) |
| 286 |
> |
.I ssh(1) |
| 287 |
|
to execute commands remotely on another machine. |
| 288 |

The arguments and behavior of this program must be identical to the UNIX |
| 289 |
< |
.I rsh |
| 289 |
> |
.I ssh |
| 290 |
|
command, except that the |
| 291 |
|
.I -l |
| 292 |
|
option will always be used to specify an alternate user name rather than the |
| 298 |
|
.I -n |
| 299 |
|
option will always be used, and the expected starting directory will |
| 300 |
|
be that of the remote user, just as with |
| 301 |
< |
.I rsh. |

.I ssh. |

.BR NEXTANIM |

|
This variable specifies the next |

|
.I pinterp |
| 379 |
|
used otherwise. |

(The default value for number of samples is 5.)\0 |
| 381 |

To simulate a particular camera's aperture, divide the focal length of |
| 382 |
+ |
the lens by the f-number, then convert to the corresponding |
| 383 |
+ |
world coordinate units. |
| 384 |
+ |
For example, if you wish to simulate a 50mm lens at f/2.0 in |
| 385 |
+ |
a scene modeled in meters, then you divide 50mm by 2.0 to get 25mm, |
| 386 |
+ |
which corresponds to an effective aperture of 0.025 meters. |
| 387 |
|
The default aperture is 0, meaning no depth-of-field blurring. |
| 388 |
|
This option does not currently work with the |
| 389 |
|
.I ANIMATE |
| 585 |
|
This requirement may be circumvented by substituting the |
| 586 |
|
.I on(1) |
| 587 |
|
command for |
| 588 |
< |
.I rsh(1) |
| 588 |
> |
.I ssh(1) |
| 589 |
|
using the |
| 590 |
|
.I RSH |
| 591 |
|
control variable, or by writing a custom remote execution script. |
| 609 |
|
Since most modern machines use IEEE floating point, this is not |
| 610 |
|
usually a problem, but it is something to keep in mind. |
