Animation Nodes¶

Animation nodes apply continuous, per-frame behaviors to objects. They compile into the components[] array in scene.json.

All animation nodes require an AR Object node connected to their Target input.

JS Animation¶

Node ID: WEBARNodeJSAnimation

Applies a continuous JavaScript-driven animation to the target object.

Inputs:

Socket	Type	Description
Target	Object	The AR Object to animate

Properties:

Property	Values	Description
Type	Rotate Y / Float	The animation type
Speed	0–10	Speed multiplier

Compiled output:

{
  "object": "MyObject",
  "type": "ROTATE",
  "speed": 1.5
}

Pulse¶

Node ID: WEBARNodePulse

Makes the object rhythmically scale in and out — a breathing or heartbeat effect.

Inputs:

Socket	Type	Description
Target	Object	The AR Object to pulse

Properties:

Property	Range	Description
Speed	0–10	Pulses per second
Amplitude	0–5	How much the scale changes. `0.1` = subtle, `0.5` = dramatic

Compiled output:

{
  "object": "MyObject",
  "type": "pulse",
  "speed": 1.0,
  "amplitude": 0.25
}

Spin¶

Node ID: WEBARNodeSpin

Rotates the object continuously around a chosen axis.

Inputs:

Socket	Type	Description
Target	Object	The AR Object to spin

Properties:

Property	Values	Description
Axis	X / Y / Z	Rotation axis
Speed	0–20	Rotation speed multiplier

Compiled output:

{
  "object": "MyObject",
  "type": "spin",
  "axis": [0, 1, 0],
  "speed": 2.0
}

Axis values: X = [1,0,0], Y = [0,1,0], Z = [0,0,1].

Combining animations¶

You can apply multiple animation nodes to the same object by connecting multiple nodes to the same AR Object output. For example: Pulse + Spin gives a spinning, pulsing object.

AR Object ──► Spin (Y, speed 1.0)
           └─► Pulse (speed 2.0, amplitude 0.1)
