The gaussian function is one of a handful of Radial Basis Functions(RBF). The wiki link shows that it can also be extended to 2 Dimensions (an additional y-axis) by modifying the exponential power: http://en.wikipedia.org/wiki/Gaussian_function

The inv multiquadric is also a RBF: (x^2 + c^2)^(-a) where c and a are constants.

Is it possible to extend this to 2 Dimensions also?
