Three.js line vector to cylinder?

I have this to create a line between 2 points:

var geometry = new THREE.Geometry();
geometry.vertices.push(new THREE.Vector3(0, 0, 0));
geometry.vertices.push(new THREE.Vector3(20, 100, 55));
var line = new THREE.Line(geometry, material, parameters = { linewidth: 400 });
scene.add(line);

(The line width, does not have any effect.)

My question is how do I transform this to a cylinder? I want to create a cylinder between two points.
