1. A method for forming an electropotential map, comprising:
- measuring locations of points on a surface of a body organ;
measuring electrical potentials of a subset of the points;
assigning respective resistances to line segments joining the points so as to define a resistor mesh; and
generating an electropotential map of the surface by applying an harmonic function to the resistor mesh responsive to the measured electrical potentials.
