## SlerpUnclamped(Quaternion, Quaternion, float)

Spherically linear interpolates between unit quaternions `a` and `b` by t.

```csharp
public static Quaternion SlerpUnclamped(Quaternion a, Quaternion b, float t)
```

### Parameters

**** (\[Quaternion]\(/engine/6000.7/script-reference/unityengine/quaternion)): Start unit quaternion value, returned when t = 0.**** (\[Quaternion]\(/engine/6000.7/script-reference/unityengine/quaternion)): End unit quaternion value, returned when t = 1.**** (\[float]\(https\://learn.microsoft.com/dotnet/api/system.single)): Interpolation ratio. Value is unclamped.

### Returns

| Type                                                                    | Description                                                                      |
