By default, |
| 74 |
+ |
.I gendaymtx |
| 75 |
+ |
assumes the positive Y-axis points north such that the first sky patch |
| 76 |
+ |
is in the Y-axis direction on the horizon, the second patch is just |
| 77 |
+ |
west of that, and so on spiraling around to the final patch near the zenith. |

.I \-r |
| 80 |

(or |
| 81 |

.I \-rz) |
| 82 |
+ |
option rotates the sky the specified number of degrees counter-clockwise |
| 83 |

about the zenith, i.e., west of north. |
| 84 |

This is in keeping with the effect of passing the output of |

.I gendaylit(1) |

The |

than visible radiance. |

Finally, the |
| 105 |
|
.I \-v |
| 106 |
|
option will enable verbose reporting, which is mostly useful for |
| 122 |
|
based on Jean-Jacques Delaunay's original gendaylit(1) implementation. |
