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. |

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". |

| 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 |
