Instance Property


The number of subdivisions around the circumference of the tube. Animatable.


var radialSegmentCount: Int { get set }


A larger number of segments adds more vertex data to the geometry, creating a smoother curve for the tube’s circular inner and outer surfaces at a cost to rendering performance.

The default segment count is 48. Setting this property’s value to a number less than 3 results in undefined behavior.

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