# screenSpaceRadius

The maximum radius (in pixels) of the geometry’s bounding sphere for this level of detail to appear.

## Declaration

```swift
var screenSpaceRadius: CGFloat { get }
```

## Discussion

Discussion When rendering a geometry with associated levels of detail, SceneKit calculates the radius in pixels of the circle covered by a geometry’s bounding sphere, then renders the geometry for the SCNLevelOfDetail object with the smallest radius parameter larger than that circle.
