　　This paper considers the finite directional difference method(FDDM)on the 2D scattered point distribution.Based on some theoretical analyses to the FDDM,we obtain new difference formulae for computing first-order and second-order directional differentials,in which the difference coefficients related to scattered neighboring points have definite geometric meanings,and consequently present a new method to select neighboring points on the 2D scattered point distribution.
