followed by an optional lower case view type.) |
591 |
|
The letters indicate the desired view position, where upper case "X" |
592 |
|
means maximum X, lower case "y" means minimum Y and so on. |
593 |
|
The final letter is the view type, where 'v' is perspective (the |
594 |
|
default), 'l' is parallel, 'a' is angular fisheye, 'h' is |
595 |
< |
hemispherical fisheye and 'c' is for cylindrical panorama. |
596 |
< |
A perspective view from maximum X, minimum Y would be "Xy" or |
597 |
< |
"Xyv". |
595 |
> |
hemispherical fisheye, 's' is for planisphere (stereographic) fisheye, |
596 |

and 'c' is for cylindrical panorama. |
597 |

A perspective view from maximum X, minimum Y would be "Xy" or "Xyv". |
