# aspect

The aspect ratio of the light’s shape.

## Declaration

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

## Discussion

Discussion If the light’s type is MDLLightType.discArea,  MDLLightType.rectangularArea, or MDLLightType.superElliptical, this property determines the lengths of the shape’s major and minor axes (longer and shorter dimensions) relative to the areaRadius property’s value.
