Instance Property


The radius of the tube’s outer circular cross section. Animatable.


var outerRadius: CGFloat { get set }


The tube is centered in its local coordinate system. For example, a tube whose outer radius is 5.0 extends from -5.0 to 5.0 along the x- and z-axes. The default outer radius is 0.5.

An outer radius of zero or less, or equal to or smaller than the inner radius, creates an empty geometry.

You can animate changes to this property’s value. See Animating SceneKit Content.
