# ToRotationSlow3D(float, Quaternion, TransformPlane)

> Transform a 2D angle into a 3D rotation using the selected transform plane (Slow). The transformation is slower because the rotation is more complex due to the fact that changing a single axis of rotation requires it to not affect any other axis rotations. If PhysicsWorld.TransformPlane.Custom is used, PhysicsWorld.TransformPlane.XY will be used instead which may not provide the correct results.

## Definition

* **Type:** Method
* **Namespace:** [Unity.U2D.Physics](/engine/6000.6/script-reference/unity/u2d/physics.md)

```csharp
public static Quaternion ToRotationSlow3D(float angle, Quaternion reference, PhysicsWorld.TransformPlane transformPlane = TransformPlane.XY)
```

### Parameters
