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-(.5t)*(.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.
