| angle | The rotation angle in degrees. The value is in the range [0, 360]. |
| axis | The axis of rotation as a normalized Vector3. If the quaternion represents no rotation, the axis defaults to Vector3.right. |
Converts a rotation to angle-axis representation.
This method decomposes the quaternion into an angle (in degrees) and a unit vector representing the axis of rotation. Normalize the quaternion before calling this method, otherwise Unity throws an exception.

public class Example : MonoBehaviour { void Start() { // Extracts the angle - axis from euler angle rotation Quaternion rotation = Quaternion.Euler(0, 90, 0); rotation.ToAngleAxis(out float angle, out Vector3 axis); // angle is 90 // axis is (0, 1, 0)
// Extracts the angle - axis rotation from the transform rotation float transformRotationAngle = 0.0f; Vector3 transformRotationAxis = Vector3.zero; transform.rotation.ToAngleAxis(out transformRotationAngle, out transformRotationAxis); } }
