Instance Property


The radius of the circular hole through the tube. Animatable.


var innerRadius: CGFloat { get set }


The tube is centered in its local coordinate system. For example, if a tube has an inner radius of 1.0, the cylindrical hole through its center extends from -0.5 to 0.5 along the x- and z-axes. The default inner radius is 0.25.

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

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