The Inverse property of the Rotation struct returns the inverse of the current rotation. The inverse of a rotation is a rotation that, when applied after the original rotation, results in no net rotation. This is useful for undoing a rotation or for calculating relative rotations.
To use the Inverse property, simply access it on an instance of a Rotation object. This will return a new Rotation object that represents the inverse of the original rotation.
// Create a rotation from an axis and angle Rotation rotation = Rotation.FromAxis(new Vector3(0, 1, 0), 90); // Get the inverse of the rotation Rotation inverseRotation = rotation.Inverse; // Use the inverse rotation // For example, applying the inverse rotation after the original rotation // should result in no net rotation Rotation result = rotation * inverseRotation; // result should be equivalent to Rotation.Identity
