For functions of two variables, geometric interpretation of which corresponds to the surface dependency engine parameters, developed an effective method of approximation by methods interlinatsiyi functions. This proposed new method of interpolation functions of one variable with spline basis. This method allows comparison of analytical methods interpolate the function of one variable of arbitrary smoothness class using basic splines with optimal number of operations. And also offer a general method for constructing closed surfaces of feather vanes on a given section surfaces. This method is a generalization of the known method Koons on modeling complex surfaces. We consider the optimal choice of input data for the construction of interpolation functions of two variables.
