QuaternionSignal

Contents

Contents

The QuaternionSignal class monitors rotation in a quaternion representation.

Inherits From : ISignal

Properties

Property	Description
`eulerAngles`	(get) eulerAngles: PointSignal (set) (Not Available) 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 (set) (Not Available) Represents the W component of the quaternion.
`x`	(get) x: ScalarSignal (set) (Not Available) Represents the X component of the quaternion.
`y`	(get) y: ScalarSignal (set) (Not Available) Represents the Y component of the quaternion.
`z`	(get) z: ScalarSignal (set) (Not Available) Represents the Z component of the quaternion.

Methods

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> history(framesCount: number, initialValues: Array<Rotation>): 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.
