(That is, an optional upper or lower case X followed by an optional |
| 589 |
|
upper or lower case Y followed by an optional upper or lower case Z |
| 590 |
< |
followed by an optional lower case V, L, A, H or C.) |
| 590 |
> |
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". |
| 598 |
|
A parallel view from maximum Z would be "Zl". |
| 599 |
|
If "ZONE" is an interior zone, the standard views will |

| 635 |
|
Just briefly, the "-vt?" option sets the view type, where "?" is |

< |
replaced by one of the letters "v, l, a, h or c", corresponding to |
| 636 |
> |
replaced by one of the letters "v, l, a, h, s or c", corresponding to |
| 637 |

perspective, parallel, angular fisheye, hemispherical fisheye |
| 638 |
|
and cylindrical panorama, respectively. |
| 639 |

The "-vp x y z" option sets the view position (eyepoint), where "x y z" |
