# worldTransform

The position and orientation of the result relative to the world coordinate system.

## Declaration

```swift
var worldTransform: simd_float4x4 { get }
```

## Discussion

Discussion This transform matrix indicates the intersection point between the detected surface and the ray that created the hit-test result. A hit-test projects a 2D point in the image or view coordinate system along a ray into the 3D world space and reports results where that line intersects detected surfaces. The session configuration’s worldAlignment property defines the world coordinate system.
