FaceTrackingModule

Example

//==============================================================================
// The following example demonstrates how to control the rotation and scale of
// an object using face rotation and mouth openness.
//
// Project setup:
// - Insert a plane
//==============================================================================

// Load in the required modules
const FaceTracking = require('FaceTracking');
const Scene = require('Scene');

// Locate the plane in the Scene
// Enable async/await in JS [part 1]
(async function() {
  const [plane] = await Promise.all([
    Scene.root.findFirst('plane0')
  ]);

  // Store a reference to a detected face
  const face = FaceTracking.face(0);

  //==============================================================================
  // Control the rotation of the plane with the rotation of the face
  //==============================================================================

  // Store references to the transform of the plane and face
  const planeTransform = plane.transform;
  const faceTransform = face.cameraTransform;

  // Bind the rotation of the face to the rotation of the plane
  planeTransform.rotationX = faceTransform.rotationX;
  planeTransform.rotationY = faceTransform.rotationY;
  planeTransform.rotationZ = faceTransform.rotationZ;

  //==============================================================================
  // Control the scale of the plane with mouth openness
  //==============================================================================

  // Store a reference to the mouth openness with some additional mathematical
  // operations to amplify the signal
  const mouthOpenness = face.mouth.openness.mul(4).add(1);

  // Bind the mouthOpenness signal to the x and y-axis scale signal of the plane
  planeTransform.scaleX = mouthOpenness;
  planeTransform.scaleY = mouthOpenness;
// Enable async/await in JS [part 2]
})();
