Abstract: This paper gives a surface fitting method for irregular 3-D data,the BP net presented needn’t delete the irregular data,then it holds the information integrality,furthermore,the surface gived is smooth and takes on good continuity,the local details are comprehensive,and it has local derviations at any point.

Key words: irregular data, surface fitting, Back-Propagation
