# simdWorldFront

The “forward” (-Z) direction vector relative to the node, expressed in world space.

## Declaration

```swift
var simdWorldFront: simd_float3 { get }
```

## Discussion

Discussion Reading this property is equivalent to reading the simdLocalFront class property and using the simdConvertVector(_:to:) or simdConvertVector(_:from:) method to convert that vector from the node’s local coordinate space to the scene’s world coordinate space.
