|
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". |

|
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" |
| 745 |
|
to maintain a specific pixel aspect ratio (1 by default). |
| 746 |
|
|
| 747 |
|
The default value for this variable is "512". |

.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.) |
