1. A method for mapping electrophysiological information on a three-dimensional model comprising:

  • A) obtaining a three-dimensional model of a portion of an anatomy comprising position information for a plurality of location points on a surface of the portion of the anatomy;

    B) obtaining an electrophysiology map comprising position information for a plurality of measurement points and electrophysiology measurements made at each of the plurality of measurement points;

    C) choosing a location point from the plurality of location points in the three-dimensional model and determining a pair of closest measurement points from the electrophysiology map;

    D) defining an edge between the pair of closest measurement points;

    E) repeating steps C) and D) for at least a first subset of the plurality of location points in the three-dimensional model, thereby defining a plurality of edges connecting at least some of the plurality of measurement points within the electrophysiology map;

    F) defining a plurality of polygons from the plurality of edges; and

    G) identifying one of the plurality of location points from the three-dimensional model, identifying one of the plurality of polygons whose edges surround the identified location point, and assigning an electrophysiology level to the identified location point using electrophysiology measurements measured at one or more vertices of the identified polygon.
