.SH NAME |

|
ranimate - compute a RADIANCE animation |
| 271 |
|
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. |

command, except that the |
| 291 |

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 |

This variable specifies the aperture diameter for depth-of-field blurring, |

A number of samples may be given as a second argument, which controls the |

number of additional frames computed and averaged together by |

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. |

This option does not currently work with the |
| 389 |
|
.I ANIMATE |
| 390 |
|
variable, since pinterp only works for static environments. |
| 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. |

|
Since most modern machines use IEEE floating point, this is not |
| 610 |
|
usually a problem, but it is something to keep in mind. |
