A method for determining boundary hypersurfaces from data matrices includes identifying intermediate hypersurfaces, situated between two respective matrix elements, that correspond to at least a portion of at least one boundary hypersurface to be determined. The identified intermediate hypersurfaces are represented by points that are adjacent to the intermediate hypersurfaces. The points that are adjacent to the intermediate hypersurfaces are connected by at least one respective closed curve. Hypersurface components formed by the closed curves are combined to form at least one boundary hypersurface.
