NAME
genclock - generate a RADIANCE description of a clock
SYNOPSIS
genclock [ -f face_mat ][ -c case_mat ][ -n name ] { HH:MM | hours }
DESCRIPTION
Genclock produces a RADIANCE scene description of an analog clock
showing the given hour. The hour may either be given as HH:MM or
decimal hours.
The face of the clock will have a radius of 1.0 units, with the
surrounding case 1.1 (2.2 diameter). The origin is at the center of
the back, and the face looks in the positive X-direction. The 12
o’clock direction corresponds to the positive Z-axis. (The Y-axis
direction is 3 o’clock.) The xform(1) command may be used to resize
and relocate the clock as desired.
Normally, genclock produces all of the materials necessary for its own
description, but options are provided to specify alternate materials
for the face and case. The numbers on the face are in dark lettering,
so the face material must be relatively light for them to show up well.
By default, the clock is given the name "clock," but this may be
changed with the -n option.
EXAMPLE
To produce a 12 inch diameter clock showing 10:35 and hang it at 60 on
a wall facing the Y-direction at Y=10:
genclock 10:35 | xform -s 6 -rz 90 -t 20 10 60
