# worldToViewMatrix

The world-to-view transformation matrix this frame interpolator uses as part of its operation.

## Declaration

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

## Discussion

Discussion Set this and viewToClipMatrix to the matrices you use to render the scene into the color buffer. This frame interpolator derives camera-only motion from the pair, and treats two identity matrices as “not supplied”.
