Help with translating points from processing for use in grasshopper

Hi, can someone help with what is likely a simple question from an inexperienced processing user.

I would like to import raw point data from face osc using this method:

CreativeInquiry/FaceOSC-Templates/blob/a68f00d02955cbd09dc027f9b65012a18cc9acf2/processing/FaceOSCRawReceiver/FaceOSCRawReceiver.pde

// Processing 3.0x template for receiving raw points from
// Kyle McDonald's FaceOSC v.1.1 
// https://github.com/kylemcdonald/ofxFaceTracker
//
// Adapted by Kaleb Crawford and Golan Levin, 2016-7, after:
// 2012 Dan Wilcox danomatika.com
// for the IACD Spring 2012 class at the CMU School of Art
// adapted from from Greg Borenstein's 2011 example
// https://gist.github.com/1603230

import oscP5.*;
OscP5 oscP5;
int found;
float[] rawArray;
int highlighted; //which point is selected

//--------------------------------------------
void setup() {
  size(640, 480);
  frameRate(30);

I would like to translate the coordinate system for x,y, and z and print to the PrintWriter stream as a vector to be read using grasshopper’s Import coordinates node.

but I am unclear on how to apply it to the array coming from face osc.
