Abstract: The study of interpolation is important to establish model of data field in Visualization. Firstly, the principle of Universal Kriging and Thin Plate Spline is presented, and the dual form of the Universal Kriging is deduced. Secondly, Thin-plate spline being a special case of Universal Kriging is demonstrated. Finally, by comparing the difference of theory and practice between Universal Kriging and Thin Plate Spline came to a conclusion that the effect of the Universal Kriging is better than that of the Thin Plate Spline.

Key words: computer application, data visualization, Thin Plate Spline, Universal Kriging
