Fast multipole method question. Point charges vs surface charges

  1. Dec 16, 2011 #1
    In many articles authors describe FMM for particles.
    e.g.
    http://www.csci.psu.edu/seminars/fallnotes/fmm.pdf
    http://www.umiacs.umd.edu/labs/cvl/pirl/vikas/publications/FMM_tutorial.pdf

    In other articles authors describe FMM for charged surface.

    How does these formulations relates?

    Main question: How can I move from FMM formulation for particles to FMM formulation for surfaces?
    Is it simply by calculating integral(Mnk) instead of Mnk at first step? And then other steps are the same?
