# Rotation3D.SlerpPath

Constants that define the arc that a slerp operation takes.

```
enum SlerpPath
```

## Topics

### Enumeration Cases

[`case automatic`](/documentation/Spatial/Rotation3D/SlerpPath/automatic)

Spherical linear interpolation along the automatically selected arc between two rotations.

[`case shortest`](/documentation/Spatial/Rotation3D/SlerpPath/shortest)

Spherical linear interpolation along the shortest arc between two rotations.

[`case longest`](/documentation/Spatial/Rotation3D/SlerpPath/longest)

Spherical linear interpolation along the longest arc between two rotations.

### Instance Methods

[`func hash(into: inout Hasher)`](/documentation/Spatial/Rotation3D/hash(into:))

Hashes the essential components of this value by feeding them into the given hasher.

### Operator Functions

[`static func == (Rotation3D, Rotation3D) -> Bool`](/documentation/Spatial/Rotation3D/==(_:_:))

Returns a Boolean value that indicates whether two values are equal.
