A 3D Interpolation Method Based on Hypersurface Spline

Interpolation in 3D space is an important data process approach.This paper extends the surface spline method of 2D interpolation and brings out a new 3D interpolation method—hypersurface spline method.The method of constructing the hypersurface spline function and the numerical implement procedure of 3D interpolation by the means of hypersurface spline function is also presented in this paper.Finally,it gives an example that generating regular 3D spatial dataset based on the interpolation of hypersurface spline,it testifies the feasibility and veracity of this method.
