# cornerSegmentCount

The number of line segments used to create each rounded corner of the plane. Animatable.

## Declaration

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

## Discussion

Discussion A larger number of segments adds more vertex data to the geometry, creating a smoother curve for each rounded corner at a cost to rendering performance. The default corner segment count is 10. 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.
