(The establishment of a Mobile-based least squares (Moving Least-Squares MLS) method of curve and surface fitting method to the traditional method of least squares (LS) method were compared for improvement so that curves and surfaces generated with a precision high smoothness of the advantages of a good many details of the principle of moving least square method and given the characteristics of applications and the use of moving least square method of curve and surface fitting procedure is given the final design process and the space curve fitting scattered data surface to be Fitting the results of cases will be cost-effective and least square fitting results of a comparative analysis of the MLS fitting of smooth curves and surfaces and fitting quality demonstrates the superiority of the method and effectiveness of)
