```

## Parameters

- `commandQueue`: The command queue of a metal device that creates the command buffer.
- `sessionAttributes`: Rendering session attributes loaded from a cinematic asset.
- `preferredTransform`: The preferred transform of the rendered image for display purposes. Always the identity transform or a multiple of a 90º rotation with no scaling.
