# horizonElevation

The angle, in radians relative to center, below which to render the ground color.

## Declaration

```swift
var horizonElevation: Float { get set }
```

## Discussion

Discussion By default, Model I/O renders an infinite sky above and below. If you set the groundColor property, Model I/O renders a solid color for all areas of the cube texture below this elevation. An elevation of 0.0 renders a horizon at the center elevation of the sky cube; negative values lead to a lower horizon and positive values to a higher horizon.
