The Zone entry windows may be manipulated in the following ways. |
401 |
– |
Control-U clears the current window. |
401 |
|
Control-V pastes the contents of the current selection at the |
402 |
|
insertion point. |

The "Auto" button may be used to set these values based on the bounding |
406 |
+ |
box of one or more Radiance scene files. |
407 |
+ |
|
408 |
+ |
.Zone.Auto |
409 |
+ |
|
410 |
+ |
Use this button to automatically determine the bounding box for this |
411 |
+ |
zone, based on the output of the "getbbox" command run on one or |
412 |
+ |
more Radiance scene files. |
413 |
+ |
The appropriate scene files are entered via a file |
414 |
+ |
selection dialogue box, which comes up after the button is pressed. |
415 |
+ |
|
416 |
+ |
The reason for selecting specific files rather than running getbbox |
417 |
+ |

external objects, which may be present in the complete scene |

The "Detail" setting indicates the relative level |
505 |
|
(Divide total lumens by 179 lumens/watt to get watts.) |
506 |
|
|
507 |
|
The exposure value may either be given as a positive real value, or |
508 |
< |
as a real value preceeded by a '+' or '-' indicating a positive or |
508 |
> |
as a real value preceded by a '+' or '-' indicating a positive or |
509 |
|
negative number of f-stops (powers of two) from the original value. |

If no exposure is given, pfilt will automatically compute the |

|
728 |

The eye separation is used for generating stereo views of |
729 |

the scene. |
730 |
+ |
It is the measured distance between a viewer's pupils in world |
731 |
+ |
coordinate units. |
732 |
+ |
It is not used directly by rad, but should be set for other programs |
733 |
+ |
that need it, such as rholo and glrad. |
