genworm - generate a RADIANCE description of a functional
worm
genworm mat name `x(t)' `y(t)' `z(t)' `r(t)' nseg [ -e expr
][ -f file ]
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.
To generate a banana:
genworm yellow banana `0' `5*sin(t)' `5*cos(t)' `.4-(.5t)*(.5-t)'

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.
