In the definition of a torus as a surface of revolution, the pipe radius defines a circle that is rotated around an axis (the Y axis of the torus’ local coordinate space). Rotating the circle around this axis makes it follow a circular path (whose radius is defined by the
ring property) and creates the surface of the torus.
The default pipe radius is
0. A pipe radius of zero or less creates an empty geometry.
You can animate changes to this property’s value. See Animating SceneKit Content.
