A worm is a malware that is designed to propagate and spread across networks. Worms are known to propagate using one or several of different transmission vectors like email, IRC, network shares, instant messengers (IM), and peer-to-peer (P2P) networks.

Worms do not infect files, but may carry one or more payloads, such as computer security compromise and information theft.

Worms typically modify system settings to automatically start. Users may need to terminate worms before they can be deleted. Also, restoring affected systems may require procedures other than scanning with an antivirus program.

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 AUTHOR
Greg Ward 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. SEE ALSO
