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
