WorldTransform

The WorldTransform class describes an object tranform for a sceneObject in world space.

Properties

PropertyDescription
position
(get) position: PointSignal
(set) position: PointSignal


Specifies the object position along the X, Y and Z axis of the world coordinate system.
rotationX
(get) rotationX: ScalarSignal
(set) (Not Available)


Represents rotation about the X-axis of the world 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.
rotationY
(get) rotationY: ScalarSignal
(set) (Not Available)


Represents rotation about the Y-axis of the world 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 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 world 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: PointSignal
(set) (Not Available)


Represents scale in the world coordinate system.
scaleX
(get) scaleX: ScalarSignal
(set) (Not Available)


Represents scale along the X-axis of the world coordinate system.
scaleY
(get) scaleY: ScalarSignal
(set) (Not Available)


Represents scale along the Y-axis of the world coordinate system.
scaleZ
(get) scaleZ: ScalarSignal
(set) (Not Available)


Represents scale along the Z-axis of the world coordinate system.
x
(get) x: ScalarSignal
(set) (Not Available)


Represents the offset along the X-axis of the world coordinate system.
y
(get) y: ScalarSignal
(set) (Not Available)


Represents the offset along the Y-axis of the world coordinate system.
z
(get) z: ScalarSignal
(set) (Not Available)


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

Methods

MethodDescription
applyTo
applyTo(transform: TransformSignal): TransformSignal


Returns a signal with the value that is equal to the value of the provided transformation with the transformation of the current TransformSignal applied to it.
applyToPoint
applyToPoint(signal: PointSignal): PointSignal


Returns a signal with the value that is equal to the value of the provided point with the transformation applied to it.
This performs a matrix multiplication of the provided point (with an implicit 1 in the 4th dimension) and the receiver transform, and divides by perspective.
applyToVector
applyToVector(signal: VectorSignal): VectorSignal


Returns a signal with the value that is equal to the value of the provided vector with the transformation applied to it.
This performs a matrix multiplication of the provided vector (with an implicit 0 in the 4th dimension) and the receiver transform, without change of position.
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.
lookAt
lookAt(targetPosition: PointSignal): TransformSignal
lookAt(targetPosition: PointSignal, selfUp: VectorSignal): TransformSignal

Default selfUp is ReactiveModule.vector(0, 1, 0).

Creates a scene object transform with rotation in direction of target.
Note: The self needs to be pointing the scene object alongside the X axis.
toSignal
toSignal(): TransformSignal


Returns a signal for a given transformation.
