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
