1. In a data processing system that executes a program of instructions, a method for inverting a point X on a distorted surface in a detail-in-context presentation for display on a display screen, comprising the steps of:

  • (a) locating a first approximation point Pi, for an inversion of the point X, wherein the point Pi is on an undistorted surface; and

    ,(b) obtaining a point PiD by displacing the point Pi, onto the distorted surface by applying a distortion function D;

    calculating a magnitude of the difference|PiD

    X| between the point X and the point PiD;

    determining whether the point Pi is acceptable for the inversion of the point X by comparing the magnitude of the difference to a tolerance δ

    ; and

    , displaying the point Pi on the display screen if the point Pi is acceptable for the inversion of the point X.
