|
Also, there are several standard view identifiers defined by |
| 296 |
|
.I rad. |
| 297 |
|
These standard views are specified by strings of the form |
| 298 |
< |
"[Xx]?[Yy]?[Zz]?[vlcah]?". |
| 298 |
> |
"[Xx]?[Yy]?[Zz]?[vlcahs]?". |

|
(That is, an optional upper or lower case X followed by an optional |
| 300 |
|
upper or lower case Y followed by an optional upper or lower case Z |
| 301 |
|
followed by an optional lower case V, L, C, A or H.)\0 |
| 303 |
|
means maximum X, lower case means minimum and so on. |
| 304 |
|
The final letter is the view type, where 'v' is perspective (the |
| 305 |
|
default), 'l' is parallel, 'c' is a cylindrical panorama, |
| 306 |
< |
'a' is angular fisheye, and 'h' is hemispherical fisheye. |
| 306 |
> |
'a' is angular fisheye, 'h' is hemispherical fisheye, and 's' |
| 307 |
> |
is a planisphere (stereographic) fisheye. |
| 308 |
|
A perspective view from maximum X, minimum Y would be "Xy" or "Xyv". |
| 309 |
|
A parallel view from maximum Z would be "Zl". |
| 310 |
|
If "ZONE" is an interior zone, the standard views will |

|
.BR PICTURE |
| 372 |
|
This is the root name of the output picture file(s). |
| 373 |

This name will have appended the view identifier (or a number if no |
| 374 |
< |
id was used) and a ".pic" suffix. |
| 374 |

id was used) and a ".hdr" suffix. |
| 375 |
|
If a picture corresponding to a specific view exists and is not out |
| 376 |
|

| 377 |
|
re-rendered. |
