# worldTransform

A matrix, in scene coordinates, that determines the object’s pose in the scene.

## Declaration

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

## Discussion

Discussion The value of this property requires orthogonal basis vectors and uniform scale. The framework interprets the transform’s position values in a right-handed coordinate system, where the Y axis extends upward and and the negative Z axis extends forward.
