How to use

lerp

method

in

com.google.ar.sceneform.math.Vector3

private void updatePosition(FrameTime frameTime) {
 // Store in local variable for nullness static analysis.
 Vector3 desiredLocalPosition = this.desiredLocalPosition;
 if (desiredLocalPosition == null) {
  return;
 }
 Vector3 localPosition = getTransformableNode().getLocalPosition();
 float lerpFactor = MathHelper.clamp(frameTime.getDeltaSeconds() * LERP_SPEED, 0, 1);
 localPosition = Vector3.lerp(localPosition, desiredLocalPosition, lerpFactor);
 float lengthDiff = Math.abs(Vector3.subtract(desiredLocalPosition, localPosition).length());
 if (lengthDiff <= POSITION_LENGTH_THRESHOLD) {
  localPosition = desiredLocalPosition;
  this.desiredLocalPosition = null;
 }
 getTransformableNode().setLocalPosition(localPosition);
}
