NAME

       genworm - generate a RADIANCE description of a functional worm

SYNOPSIS

       genworm mat name 'x(t)' 'y(t)' 'z(t)' 'r(t)' nseg [ -e expr ][ -f file ]

DESCRIPTION

       Genworm  produces  a RADIANCE scene description of a worm defined by the parametric equations x(t), y(t),
       z(t), and r(t) (the radius).  T will vary from 0 to 1 in steps of 1/nseg.  The surface will  be  composed
       of  nseg  cones  or  cylinders and nseg+1 spheres.  The expressions are of the same type used in RADIANCE
       function files.  Auxiliary expressions and/or files may be specified in any number of -e and -f options.

EXAMPLE

       To generate a banana:

         genworm yellow banana '0' '5*sin(t)' '5*cos(t)' '.4-(.5-t)*(.5-t)' 20

BUGS

       Since the worm is constructed of intersecting surfaces, only opaque materials should be  used  with  this
       object.  Also, a worm cannot double back inside itself without making a mess.
