# TransformSignal

### Properties

PropertyDescription

`position`

``````(get) scale: PointSignal
(set) (Not Available)
``````

Represents the offset in the local coordinate system.

`rotationX`

``````(get) rotationX: ScalarSignal
(set) (Not Available)
``````

Represents rotation about the X-axis of the local coordinate system, in radians. The signal value is in the range [-PI, PI].

Note: The order of operations (rotations in particular) is the same as in `Transform`. The rotations are applied to the object in Z-Y-X order. The X rotation is applied first to the object, therefore it is always performed in the object's local coordinate system.

`rotationY`

``````(get) rotationY: ScalarSignal
(set) (Not Available)
``````

Represents rotation about the Y-axis of the rotated local coordinate system, in radians. The signal value is in the range [-PI/2, PI/2].

Note: The order of operations (rotations in particular) is the same as in `Transform`. The rotations are applied to the object in Z-Y-X order. The Y rotation is applied second to the object, therefore if the `rotationX` is not zero, then `rotationY` is applied not in the object's local coordinate system but in the rotated one.

`rotationZ`

``````(get) rotationZ: ScalarSignal
(set) (Not Available)
``````

Represents rotation about the Z-axis of the rotated local coordinate system, in radians. The signal value is in the range [-PI, PI].

Note: The order of operations (rotations in particular) is the same as in `Transform`. The rotations are applied to the object in Z-Y-X order. The Z rotation is applied last to the object, therefore if the `rotationX` or `rotationY` is not zero, then `rotationZ` is applied not in the object's local coordinate system but in the rotated one.

`scale`

``````(get) scale: ScaleSignal
(set) (Not Available)
``````

Represents scale in the local coordinate system.

`scaleX`

``````(get) scaleX: ScalarSignal
(set) (Not Available)
``````

Represents scale along the X-axis of the local coordinate system.

`scaleY`

``````(get) scaleY: ScalarSignal
(set) (Not Available)
``````

Represents scale along the Y-axis of the local coordinate system.

`scaleZ`

``````(get) scaleZ: ScalarSignal
(set) (Not Available)
``````

Represents scale along the Z-axis of the local coordinate system.

`x`

``````(get) x: ScalarSignal
(set) (Not Available)
``````

Represents the offset along the X-axis of the local coordinate system.

`y`

``````(get) y: ScalarSignal
(set) (Not Available)
``````

Represents the offset along the Y-axis of the local coordinate system.

`z`

``````(get) z: ScalarSignal
(set) (Not Available)
``````

Represents the offset along the Z-axis of the local coordinate system.

### Methods

MethodDescription

`applyTo`

``````applyTo(transform: TransformSignal): TransformSignal
applyTo(point: PointSignal): PointSignal
applyTo(vector: VectorSignal): VectorSignal
``````

Returns a signal with the value that is equal to the value of the provided transformation/point/vector with the transformation of the current `TransformSignal` applied to it.

`delayBy`

``````delayBy({milliseconds: number}): TransformSignal
``````

Delays a transform signal. The argument is an object with a "milliseconds" property specifying the delay duration in milliseconds.

`expSmooth`

``````expSmooth(dampFactor: number): TransformSignal
``````

Smoothes a variable signal using exponential averaging over time. The argument specifies the dampening time constant in milliseconds.

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).

Note: See also `ReactiveModule.expSmooth`.

`inverse`

``````inverse(): TransformSignal
``````

Returns a signal with the value that is equal to the inverted transformation value of the given signal at any point of time.
