The `QuaternionSignal`

class monitors rotation in a quaternion representation. **Inherits From : **`ISignal`

Property | Description |
---|---|

`eulerAngles` | (get) eulerAngles: PointSignal Represents the Euler angle from the `QuaternionSignal` , representing pitch, yaw, roll respectively.Note: the order of rotations for the Euler angles is the same as in `Transform` class. |

`w` | (get) w: ScalarSignal Represents the W component of the quaternion. |

`x` | (get) x: ScalarSignal Represents the X component of the quaternion. |

`y` | (get) y: ScalarSignal Represents the Y component of the quaternion. |

`z` | (get) z: ScalarSignal Represents the Z component of the quaternion. |

Method | Description |
---|---|

` angleAxis ` | angleAxis(): Point4DSignal Returns the angle/axis representation of this quaternion. First element in the vector is angle in radians, with last 3 being X, Y, Z axis respectively. |

` angleTo ` | angleTo(signal: QuaternionSignal): ScalarSignal Returns a signal with the value that is the angular distance between this quaternion and the provided quaternion, in radians. |

` conjugate ` | conjugate(): QuaternionSignal Returns the rotational conjugate of this quaternion. The conjugate of a quaternion represents the same rotation in the opposite direction about the rotational axis. |

` dot ` | dot(signal: QuaternionSignal): ScalarSignal Returns a scalar signal with the value that is the dot product of the given signals. |

` history ` | history(framesCount: number): SignalHistory<Quaternion> Returns an object used to access signal values from past frames. The amount of frames tracked is customizable via `framesCount` parameter.Historical signal values are going to be initialized with signal value at call time or using `initialValues` if provided. |

` invert ` | invert(): QuaternionSignal Returns the rotational conjugate of this quaternion. The conjugate of a quaternion represents the same rotation in the opposite direction about the rotational axis. |

` mix ` | mix(signal: QuaternionSignal, factor: ScalarSignal): QuaternionSignal Returns a signal with the value that is the linear interpolation between this and another signal by a given factor. |

` mul ` | mul(signal: QuaternionSignal): QuaternionSignal Returns a signal with the value that is the product of the values of the given signals. |

` pinLastValue ` | pinLastValue(): QuaternionSignal Returns a new `QuaternionSignal` containing a constant value which is the last value of the specified signal before `pinLastValue` is called. |

` slerp ` | slerp(signal: QuaternionSignal, factor: ScalarSignal): QuaternionSignal Returns a signal with the value that is the spherical linear interpolation between this and another signal by a given factor. |
