# init(forward:up:)

Creates a 3D vector orientation instance using the forward and up vectors you specify.

## Declaration

```swift
init(forward: AVAudio3DVector, up: AVAudio3DVector)
```

## Parameters

- `forward`: The forward vector points in the direction that the listener faces.
- `up`: The up vector is orthogonal to the forward vector and points upward from the listener’s head.
