.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
|
| 28 |
|
|
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.
|

|
|
.SH EXAMPLE
|

|
|
To produce a 12 inch diameter clock showing 10:35
|
| 51 |
|
|
and hang it at 60 on a wall facing the Y-direction at Y=10:
