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. |
699 |
|
|
685 |
– |
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). |
721 |
|
|
722 |
< |
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 |
|
|
758 |
|
|
759 |
|
The default value for this variable is "512". |
760 |

|
761 |
< |
.Views.Rawsave |
761 |
> |
.Views.Rawfile |
762 |
|
|
763 |
< |
The "Rawsave" check box determines whether or not the raw output picture |
763 |
> |
The "Rawfile" entry window determines if and where the raw output picture |
764 |
|
from rpict will be saved. |
765 |
< |
The default action (box unchecked) is to remove this file, since it |
765 |
> |
If the entry is empty, the file will be removed after rendering and |
766 |
> |
filtering. |
767 |
> |
This is the normal action, since the raw file |
768 |
|
takes up disk space and is not generally useful. |
769 |
< |
However, if you wish to perform some special filtering function on |
770 |
< |
the file, this file can be renamed instead of removed by checking this box. |
771 |
< |
The final name in this case will be the same as the finished |
772 |
< |
picture, except with a ".rwp" suffix. |
769 |
> |
However, if you wish to perform some special filtering function, |
770 |
> |
this file can be renamed instead of removed by giving a |
771 |
> |
root file name in this entry window. |
772 |
> |
The final name in this case will be the given root plus and |
773 |
> |
underscore plus the view name followed by a ".pic" suffix. |
774 |
|
|
775 |
+ |
In the special case when the raw file name and picture file name are |
776 |
+ |
the same, the raw file is saved and no filtering takes place. |
777 |
+ |
|
778 |
+ |
.Views.Zfile |
779 |
+ |
|
780 |
+ |
The "Zfile" entry window gives the root name of the file in which to |
781 |
+ |
store the raw (binary floating point) distances to pixels in the |
782 |
+ |
original generated image. |
783 |
+ |
If this entry is empty, then no z-file will be saved. |
784 |
+ |
|
785 |
+ |
The final z-file name will be the given root plus an underscore plus |
786 |
+ |
the view name plus a ".zbf" suffix. |
787 |
+ |
|
788 |
+ |
To convert this image to human-readable form, the program "od" will |
789 |
+ |
work on some systems, or the Radiance "pvalue" program may be used |
790 |
+ |
to first convert it to a greyscale Radiance picture using the |
791 |
+ |
options "-r -h -b -df `getinfo -d < pictname`" where "pictname" is |
792 |
+ |
replaced by the raw picture file name. |
793 |
+ |
(Getinfo simply gets the original image dimensions, which are not |
794 |
+ |
stored in the z-file.) |
795 |
+ |
|
796 |
|
.Views.Copy |
797 |
|
|
798 |
|
The "Copy" button in the Views screen permits those variables |
1282 |
|
|
1283 |
|
The "Delete" button on the Results screen is used to remove the |
1284 |
|
selected picture files from the filesystem. |
1285 |
+ |
Associated raw picture and z-buffer files |
1286 |
+ |
will also be deleted if they exist. |
1287 |
|
Verification is required before any action is taken. |
1288 |
|
|
1289 |
|
.Results.Display |
1371 |
|
The print command window on the Results screen contains the system |
1372 |
|
command to use in printing out finished Radiance pictures. |
1373 |
|
The "%s" format field, which must appear somewhere in the command, |
1374 |
< |
is replaced by the selected Radiance picture file name(s). |
1374 |
> |
is replaced by the selected Radiance picture file name. |
1375 |
> |
This command is executed multiple times if multiple files are |
1376 |
> |
selected. |
1377 |
|
|
1378 |
|
The default command is "ra_ps %s | lpr", which converts the Radiance |
1379 |
|
picture to a black and white PostScript file and sends it to the lpr |
1380 |
|
print spooler. |
1381 |
+ |
Add a "-c" option to "ra_ps" if the printer supports color. |
1382 |
|
If your printer does not understand PostScript, or your system does |
1383 |
|
not support lpr, this command must obviously be changed. |
