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:

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.
