# radialSegmentCount

The number of subdivisions around the lateral circumference of the capsule. Animatable.

## Declaration

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

## Discussion

Discussion A larger number of segments adds more vertex data to the geometry, creating a smoother curve for the capsule’s circular horizontal cross sections 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.
