.SH DESCRIPTION |
| 20 |
|
|
.I Genclock |
| 21 |
|
|
produces a RADIANCE scene description of an analog clock showing the |
| 22 |
|
|
given hour. |
| 23 |
|
|
The hour may either be given as |
| 24 |
|
|
.I HH:MM |
| 25 |
|
|
or decimal |
| 26 |
|
|
.I hours. |
| 27 |
|
|
.PP |

|
|
The face of the clock will have a radius of 1.0 units, with the |
| 29 |
|
|
surrounding case 1.1 (2.2 diameter). |
| 30 |
|
|
The origin is at the center of the back, and the face looks in the |
| 31 |
|
|
positive X-direction. |
| 32 |
|
|
The 12 o'clock direction corresponds to the positive Z-axis. |
| 33 |
|
|
(The Y-axis direction is 3 o'clock.)\0 |
| 34 |
|
|
The |
| 35 |
|
|
.I xform(1) |
| 36 |
|
|
command may be used to resize and relocate the clock as desired. |
| 37 |
|
|
.PP |
| 38 |
|
|
Normally, |
| 39 |
|
|
.I genclock |
| 40 |
|
|
produces all of the materials necessary for its own description, but |
| 41 |
|
|
options are provided to specify alternate materials for the face and |
| 42 |
|
|
case. |
| 43 |
|
|
The numbers on the face are in dark lettering, so the face material |
| 44 |
|
|
must be relatively light for them to show up well. |
| 45 |
|
|
By default, the clock is given the name "clock," but this may be |
| 46 |
|
|
changed with the |
| 47 |
|
|
.I \-n |
| 48 |
|
|
option. |
| 49 |
|
|
.SH EXAMPLE |

| 51 |
|
|
and hang it at 60 on a wall facing the Y-direction at Y=10: |
