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
