# init(ix:iy:iz:r:)

Creates a new quaternion from four scalar values that specify the imaginary and real parts.

## Declaration

```swift
init(ix: Double, iy: Double, iz: Double, r: Double)
```

## Parameters

- `ix`: The first component of the imaginary part.
- `iy`: The second component of the imaginary part.
- `iz`: The third component of the imaginary part.
- `r`: The real part.
