circular tubes (snakes)

OK does any one know of a library or code source that gives tubes (aka hoses snakes).

need
-speeds sutable for real time dynamic modeling
-tubes conect points (ie dot to dot tube)
-rounded corners

basicly I dont have the development time to implement these techniques.

Any info apreciated

I think the GLE tubing & extrusion library is part of the GLUT distro these days.
