HSVA
| HSVA(h: ScalarSignal, s: ScalarSignal, v: ScalarSignal, a: ScalarSignal): HsvaSignal
Combines four signals and returns the result as an HsvaSignal . Each value should be in the range between 0.0 and 1.0.
Note: Hue value is also specified in the range between 0.0 and 1.0. |
RGBA
| RGBA(r: ScalarSignal, g: ScalarSignal, b: ScalarSignal, a: ScalarSignal): RgbaSignal
Combines four signals and returns the result as an RgbaSignal . Each value should be in the range between 0.0 and 1.0.
Note: RGB components are interpreted in sRGB space. |
andList
| andList(x: Array<BoolSignal>): BoolSignal
Returns a signal with the value that is the logical and of the values in an array |
antiderivative
| antiderivative(signal: ScalarSignal, {min: number, max: number, initialValue: number, overflowBehaviour: ReactiveModule.AntiderivativeOverflowBehaviour}): ScalarSignal
Returns a signal that estimates the anti derivative of the given signal with respect to time (measured in milliseconds).
Note: Since the antiderivative is inherently unbound the min/max parameters must be provided to prevent overflow. when overflowBehaviour is CLAMP the output is clamped at the min/max. When overflowBehaviour is WRAP the output is wrapped. This is useful when the output represents something that is cyclic like an angle in this case min might be 0, max might be 2*PI. |
concat
| concat(lhs: StringSignal, rhs: StringSignal): StringSignal
Returns a StringSignal containing the concatenation of the values specified by the input signals.
See Also: StringSignal.concat |
derivative
| derivative(): ScalarSignal
Returns a signal that estimates the derivative of the given signal with respect to time (measured in milliseconds).
Note: the value of the derivative at the initial point of time is always set to zero.
Note: the returned signal might be noisy for certain types of input signals, especially those received from the face tracking. It is recommended to pass the input signal to expSmooth first with a damping constant in the range between 100 and 500. |
eq
| eq(lhs: ScalarSignal, rhs: ScalarSignal): BoolSignal
eq(lhs: StringSignal, rhs: StringSignal): BoolSignal
eq(lhs: BoolSignal, rhs: BoolSignal): BoolSignal
Returns a Boolean signal that takes the value of true every time when the value of the left-hand-side signal is equal to the value of the right-hand-side one, and the value of false all other time.
Note: the scalar values are tested for exact equality. For some applications it might be reasonable to perform a non-strict comparison allowing the values to be within a small distance one from another.

expSmooth
| expSmooth(signal: ScalarSignal, dampFactor: number): ScalarSignal
expSmooth(signal: PointSignal, dampFactor: number): PointSignal
expSmooth(signal: VectorSignal, dampFactor: number): VectorSignal
expSmooth(signal: TransformSignal, dampFactor: number): TransformSignal
Smoothes a variable signal using exponential averaging over time. The argument specifies the dampening time constant in milliseconds.
Note: See also ScalarSignal.expSmooth , PointSignal.expSmooth , VectorSignal.expSmooth , TransformSignal.expSmooth .
Note: The smoothed transformation for a signal that specifies a rigid body transformation is guaranteed to be a rigid body transformation. The rotation component is smoothed in spherical coordinates using Slerp (spherical linear interpolation). |
ge
| ge(lhs: ScalarSignal, rhs: ScalarSignal): BoolSignal
Returns a Boolean signal that takes the value of true every time when the value of the left-hand-side signal is greater than or equal to the value of the right-hand-side one, and the value of false all other time.
See Also: ScalarSignal.ge |
gt
| gt(lhs: ScalarSignal, rhs: ScalarSignal): BoolSignal
Returns a Boolean signal that takes the value of true every time when the value of the left-hand-side signal is strictly greater than the value of the right-hand-side one, and the value of false all other time.
See Also: ScalarSignal.gt |
le
| le(lhs: ScalarSignal, rhs: ScalarSignal): BoolSignal
Returns a Boolean signal that takes the value of true every time when the value of the left-hand-side signal is less than or equal to the value of the right-hand-side one, and the value of false all other time.
See Also: ScalarSignal.le |
lt
| lt(lhs: ScalarSignal, rhs: ScalarSignal): BoolSignal
Returns a Boolean signal that takes the value of true every time when the value of the left-hand-side signal is strictly less than the value of the right-hand-side one, and the value of false all other time.
See Also: ScalarSignal.lt |
monitorMany
| monitorMany(signals: { [string]: ScalarSignal}): EventSource
monitorMany(signals: { [string]: ScalarSignal}, config: {fireOnInitialValue: ?boolean}): EventSource
Returns an EventSource that emits an event every time when any value of the input signals change. The event contains a JSON object with the old and new values in the format:
{ "oldValues": oldValues, "newValues": newValues }
where oldValues and newValues are the JSON objects where keys are the names of the signals and values are old or new values of that signals correspondingly.
Note: By default, there is no event fired for the initial value of the signal. If config.fireOnInitialValue is set to true then an event for initial signal value is also emitted. oldValues is unset for this initial event.
See Also: ReactiveModule.monitor |
mulList
| mulList(x: Array<number>): ScalarSignal
Returns a signal with the value that is the product of the values in an array |
ne
| ne(lhs: ScalarSignal, rhs: ScalarSignal): BoolSignal
ne(lhs: StringSignal, rhs: StringSignal): BoolSignal
ne(lhs: BoolSignal, rhs: BoolSignal): BoolSignal
Returns a Boolean signal that takes the value of true every time when the value of the left-hand-side signal is not equal to the value of the right-hand-side one, and the value of false all other time.
Note: the scalar values are tested for exact equality. For some applications it might be reasonable to perform a non-strict comparison allowing the values to be within a small distance one from another.

not
| not(signal: BoolSignal): BoolSignal
Returns a signal with the logically negated value of the given signal.

schmittTrigger
| schmittTrigger(signal: ScalarSignal, config: { low: number, high: number, initialValue: ?boolean}): BoolSignal
Returns a Boolean signal that is true when the input is strictly greater than the upper threshold, and false when it is strictly less than the lower threshold.
For input values between and including the thresholds, the Shmitt trigger returns the same value as at the previous update, or initialValue if this is the first update.
Note: The initialValue is assumed to be false if it isn't specified. |
sumList
| sumList(x: Array<number>): ScalarSignal
Returns a signal with the value that is the sum of the values in an array |
val
| val(constant: number): ScalarSignal
val(constant: string): StringSignal
val(constant: boolean): BoolSignal
Returns a signal that has a constant value which is specified by the argument.
Note: Primitive types are implicitly converted to constant signals when passed as function or property-setter arguments, therefore using val in such scenarios is not required. |

Combines three signals and returns the result as a VectorSignal . |
xor
| xor(lhs: BoolSignal, rhs: BoolSignal): BoolSignal

xorList
| xorList(x: Array<BoolSignal>): BoolSignal
Returns a signal with the value that is the logical xor of the values in an array |
