# ringSegmentCount

The number of subdivisions around the torus ring. Animatable.

## Declaration

```swift
var ringSegmentCount: Int { get set }
```

## Discussion

Discussion This segment count corresponds to the circle formed by the torus’ major radius or ringRadius property. A larger number of segments adds more vertex data to the geometry, creating a more smoothly curved surface 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.
