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". |
