# init(constrainedToAxis:minimumAngleDelta:)

Creates a rotation gesture with a minimum delta for the gesture to
start and axis to constrain measurement of rotation.

```
nonisolated init(constrainedToAxis: RotationAxis3D? = nil, minimumAngleDelta: Angle = .degrees(1))
```

## Parameters

`constrainedToAxis`

The 3D axis about which rotation is measured.

`minimumAngleDelta`

The minimum delta required before the
gesture starts. The default value is a one-degree angle.

## Discussion

If the constrained axis
is `nil`, the gesture measures unconstrained 3D rotation.
