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. |
| 403 |
|
Return moves the focus to the next window in the chain. |
| 404 |
|
|
| 405 |
+ |
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 |
+ |
on the entire scene is that a zone usually does not include large |
| 418 |
+ |
external objects, which may be present in the complete scene |

.Zone.Detail |
| 422 |
|
|
| 423 |
|
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. |
| 510 |
|
|
| 511 |
|
If no exposure is given, pfilt will automatically compute the |
| 697 |
|
for the convenience of entering a new view. |
| 698 |
|
It has no effect on the rad input variables. |

Note that Control-U will always clear an entry box whose cursor is |
| 686 |

active. |

.Views.Default |
| 701 |
|
|
| 702 |
|
The "Set Default" button may be used to make the selected view the |
| 719 |
|
the positive Y axis (+Y), the positive Z axis (+Z), the negative |
| 720 |
|
X axis (-X), the negative Y axis (-Y), or the negative Z axis (-Z). |

This setting may always be overriden by the "-vu xd yd zd" option, |
| 722 |
> |
This setting may always be overridden by the "-vu xd yd zd" option, |
| 723 |
|
and will be altered for a particular view if it happens to be |
| 724 |
|
parallel to the view direction. |
| 725 |
+ |
|
| 726 |

.Views.Eyesep |
| 727 |
+ |
|
| 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. |
