# capSegmentCount

The number of subdivisions in the height of each hemispherical end of the capsule. Animatable.

## Declaration

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

## Discussion

Discussion A larger number of segments adds more vertex data to the geometry, creating a smoother curved surface for the capsule’s ends at a cost to rendering performance. The default segment count is 24. Setting this property’s value to a number less than 1 results in undefined behavior. You can animate changes to this property’s value. See Animating SceneKit Content.
