As in |
| 158 |
|
.I pfilt, |
| 159 |
|
the exposure setting may be given either as a multiplier or as a |
| 160 |
< |
number of f-stop adjustments (eg. +2 or -1.5). |
| 160 |
> |
number of f\-stop adjustments (eg. +2 or \-1.5). |
| 161 |
|
Alternatively, a file name may be given, which |
| 162 |
|
.I ranimate |
| 163 |
|
will interpret as having one exposure value per line per frame, |
| 180 |
|
and thus should contain a |
| 181 |
|
.I printf(3) |
| 182 |
|
style integer field to distinguish one frame number from another. |
| 183 |
< |
The final frames will use this name with a ".pic" suffix. |
| 183 |
> |
The final frames will use this name with a ".hdr" suffix. |
| 184 |
|
The default value is the assigned |
| 185 |
|
.I DIRECTORY |
| 186 |
|
followed by "/frame%03d". |
| 362 |
|
The default fraction is 0, meaning no motion blurring. |
| 363 |
|
This option does not currently work with the |
| 364 |
|
.I ANIMATE |
| 365 |
< |
variable, since pinterp only works for static environments. |
| 365 |

variable. |
| 366 |
|
.TP |
| 367 |
|
.BR DBLUR |
| 368 |
|
This variable specifies the aperture diameter for depth-of-field blurring, |
| 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 focus distance is determined by the length of the view directon vector. |
| 388 |
|
The default aperture is 0, meaning no depth-of-field blurring. |
| 388 |
– |
This option does not currently work with the |

variable, since pinterp only works for static environments. |

.BR RTRACE |
| 391 |
|
This boolean variable tells |

|
would use without actually executing anything, we can invoke it |
| 488 |
|
thus: |
| 489 |
|
.IP "" .2i |

ranimate -n -e sample.ran |
| 490 |
> |
ranimate \-n \-e sample.ran |
