– |
lower or iconify it rather than dismissing it if further help is |
| 60 |
– |
needed. |

.Trad.Messages |
| 61 |
|
|
| 62 |
|
Informative messages, commands executed by rad, and errors |
| 569 |
|
added to the picture file name along with the standard ".pic" suffix. |
| 570 |
|
|
| 571 |
|
The standard views are specified by strings of the form |
| 572 |
< |
"[Xx]?[Yy]?[Zz]?[vlah]?". |
| 572 |
> |
"[Xx]?[Yy]?[Zz]?[vlahc]?". |
| 573 |
|
(That is, an optional upper or lower case X followed by an optional |
| 574 |
|
upper or lower case Y followed by an optional upper or lower case Z |
| 575 |
< |
followed by an optional lower case V, L, A or H.) |
| 575 |
> |
followed by an optional lower case V, L, A, H or C.) |
| 576 |
|
The letters indicate the desired view position, where upper case "X" |
| 577 |
|
means maximum X, lower case "y" means minimum Y and so on. |
| 578 |
|
The final letter is the view type, where 'v' is perspective (the |
| 579 |
< |
default), 'l' is parallel, 'a' is angular fisheye, and 'h' is |
| 580 |
< |
hemispherical fisheye. |
| 579 |
> |
default), 'l' is parallel, 'a' is angular fisheye, 'h' is |
| 580 |
> |
hemispherical fisheye and 'c' is for cylindrical panorama. |
| 581 |
|
A perspective view from maximum X, minimum Y would be "Xy" or |
| 582 |
|
"Xyv". |
| 583 |
|
A parallel view from maximum Z would be "Zl". |
| 618 |
|
Consult the rpict(1) manual page for a full description of the various |
| 619 |
|
view options, all of which begin with "-v". |
| 620 |
|
Just briefly, the "-vt?" option sets the view type, where "?" is |
| 621 |
< |
replaced by one of the letters "v, l, a or h", corresponding to |
| 622 |
< |
perspective, parallel, angular and hemispherical fisheye, respectively. |
| 621 |
> |
replaced by one of the letters "v, l, a, h or c", corresponding to |
| 622 |
> |
perspective, parallel, angular fisheye, hemispherical fisheye |
| 623 |
> |
and cylindrical panorama, respectively. |
| 624 |
|
The "-vp x y z" option sets the view position (eyepoint), where "x y z" |
| 625 |
|
is replaced by the position in 3-space. |
| 626 |
|
The "-vd xd yd zd" option sets the view direction, where "xd yd zd" |
| 645 |
|
space between it and whatever follows. |
| 646 |
|
|
| 647 |
|
Hitting return in the "Options" window is equivalent to pressing the |
| 648 |
< |
"Add" button. |
| 648 |
> |
"Add" button followed by the "Clear" button. |
| 649 |
|
|
| 650 |
|
.Views.Add |
| 651 |
|
|
| 746 |
|
|
| 747 |
|
The default value for this variable is "512". |
| 748 |
|
|
| 749 |
+ |
.Views.Rawfile |
| 750 |
+ |
|
| 751 |
+ |
The "Rawfile" entry window determines if and where the raw output picture |
| 752 |
+ |
from rpict will be saved. |
| 753 |
+ |
If the entry is empty, the file will be removed after rendering and |
| 754 |
+ |
filtering. |
| 755 |
+ |
This is the normal action, since the raw file |
| 756 |
+ |
takes up disk space and is not generally useful. |
| 757 |
+ |
However, if you wish to perform some special filtering function, |
| 758 |
+ |
this file can be renamed instead of removed by giving a |
| 759 |
+ |
root file name in this entry window. |
| 760 |
+ |
The final name in this case will be the given root plus and |
| 761 |
+ |
underscore plus the view name followed by a ".pic" suffix. |
| 762 |
+ |
|
| 763 |
+ |
In the special case when the raw file name and picture file name are |
| 764 |
+ |
the same, the raw file is saved and no filtering takes place. |
| 765 |
+ |
|
| 766 |
+ |
.Views.Zfile |
| 767 |
+ |
|
| 768 |
+ |
The "Zfile" entry window gives the root name of the file in which to |
| 769 |
+ |
store the raw (binary floating point) distances to pixels in the |
| 770 |
+ |
original generated image. |
| 771 |
+ |
If this entry is empty, then no z-file will be saved. |
| 772 |
+ |
|
| 773 |
+ |
The final z-file name will be the given root plus an underscore plus |
| 774 |
+ |
the view name plus a ".zbf" suffix. |
| 775 |
+ |
|
| 776 |
+ |
To convert this image to human-readable form, the program "od" will |
| 777 |
+ |
work on some systems, or the Radiance "pvalue" program may be used |
| 778 |
+ |
to first convert it to a greyscale Radiance picture using the |
| 779 |
+ |
options "-r -h -b -df `getinfo -d < pictname`" where "pictname" is |
| 780 |
+ |
replaced by the raw picture file name. |
| 781 |
+ |
(Getinfo simply gets the original image dimensions, which are not |
| 782 |
+ |
stored in the z-file.) |
| 783 |
+ |
|
| 784 |
|
.Views.Copy |
| 785 |
|
|
| 786 |
|
The "Copy" button in the Views screen permits those variables |
| 911 |
|
Normally, progress reports and errors during batch renderings |
| 912 |
|
are sent to the error file given by the root of the rad input |
| 913 |
|
file name followed by the ".err" suffix. |
| 914 |
< |
(See the "Errors" topic under the "Action" screen category.) |
| 914 |
> |
(See the "CheckErr" topic under the "Action" screen category.) |
| 915 |
|
If you wish these reports and errors to be directed to a different |
| 916 |
|
file, follow the time interval by a space and a file name. |
| 917 |
|
|
| 1091 |
|
Other views may be accessed within rview using the "L name" |
| 1092 |
|
command, and new views can be added with the "V name" |
| 1093 |
|
command. |
| 1062 |
– |
(See the rview(1) man page and the "View" topic in the current |
| 1063 |
– |
help category for more information.) |
| 1094 |
|
|
| 1095 |
+ |
When using the "V" command to change an existing view, do not |
| 1096 |
+ |
give it an existing name because the previous view will not be overridden. |
| 1097 |
+ |
Instead, give it a new name (or no name, which will show up as |
| 1098 |
+ |
a number later), then use the Views screen to override the previous |
| 1099 |
+ |
view definition with the new one. |
| 1100 |
+ |
(See the "View" topic in the current |
| 1101 |
+ |
help category, the "Change" topic under "Views" and the rview(1) |
| 1102 |
+ |
manual page for more information.) |
| 1103 |
+ |
|
| 1104 |
|
If the octree is out-of-date, it will be rebuilt before rendering |
| 1105 |
|
begins. |
| 1106 |
|
|
| 1114 |
|
If the special entry "ALL" is selected, then every view in the |
| 1115 |
|
current list will be rendered if it hasn't been already. |
| 1116 |
|
|
| 1117 |
+ |
The view menu next to the "rview" button will be disabled if there |
| 1118 |
+ |
is only one view to choose from. |
| 1119 |
+ |
The view menu next to the "Start" button will be disabled if there |
| 1120 |
+ |
is a batch job in progress, and thus the view cannot be changed. |
| 1121 |
+ |
|
| 1122 |
|
The batch rendering view menu also selects the view or views |
| 1123 |
|
to use in producing a script during a dry run. |
| 1124 |
|
|
| 1139 |
|
the error file periodically. |
| 1140 |
|
(This file is named by the root of the rad input file followed by |
| 1141 |
|
".err".) |
| 1142 |
< |
When a batch process is started or already running, this button |
| 1143 |
< |
will be disabled. |
| 1142 |
> |
When a batch process is started or already running, or when a |
| 1143 |
> |
process is on another host and its status is unknown, |
| 1144 |
> |
this button will be disabled. |
| 1145 |
|
|
| 1146 |
|
The background process can be killed during this or later |
| 1147 |
|
invocations of trad using the "Kill" button. |
| 1148 |
+ |
If the process was started on another machine and the status is unknown, |
| 1149 |
+ |
it will be necessary to run trad from the other host or remove the error |
| 1150 |
+ |
file manually before starting a background process on this machine. |
| 1151 |
+ |
This is to protect you from the great confusion that results when two |
| 1152 |
+ |
machines are working from the same project file. |
| 1153 |
|
|
| 1154 |
|
.Action.Kill |
| 1155 |
|
|
| 1164 |
|
rendering, though some new startup costs will be incurred. |
| 1165 |
|
|
| 1166 |
|
The "Kill" button is disabled if no running batch process is |
| 1167 |
< |
detected. |
| 1167 |
> |
detected on the current host machine. |
| 1168 |
|
|
| 1169 |
|
.Action.CheckErr |
| 1170 |
|
|
| 1270 |
|
|
| 1271 |
|
The "Delete" button on the Results screen is used to remove the |
| 1272 |
|
selected picture files from the filesystem. |
| 1273 |
+ |
Associated raw picture and z-buffer files |
| 1274 |
+ |
will also be deleted if they exist. |
| 1275 |
|
Verification is required before any action is taken. |
| 1276 |
|
|
| 1277 |
|
.Results.Display |
| 1359 |
|
The print command window on the Results screen contains the system |
| 1360 |
|
command to use in printing out finished Radiance pictures. |
| 1361 |
|
The "%s" format field, which must appear somewhere in the command, |
| 1362 |
< |
is replaced by the selected Radiance picture file name(s). |
| 1362 |
> |
is replaced by the selected Radiance picture file name. |
| 1363 |
> |
This command is executed multiple times if multiple files are |
| 1364 |
> |
selected. |
| 1365 |
|
|
| 1366 |
|
The default command is "ra_ps %s | lpr", which converts the Radiance |
| 1367 |
|
picture to a black and white PostScript file and sends it to the lpr |
| 1368 |
|
print spooler. |
| 1369 |
+ |
Add a "-c" option to "ra_ps" if the printer supports color. |
| 1370 |
|
If your printer does not understand PostScript, or your system does |
| 1371 |
|
not support lpr, this command must obviously be changed. |
