THREE.TubeGeometry creates a tube that extrudes along a 3D spline. You specify the path using a number of vertices, and THREE.TubeGeometry will create the tube. An example that you can experiment with can be found in the sources for this chapter (04-extrude-tube.html). The following screenshot shows this example:

With the controls in the upper-right corner, we can define how the tube looks or generate a new tube by clicking on the newPoints button. The code needed to create a tube is very simple, as follows:
