 Selecting an appropriate shape parameter for radial basis function mappings can be a bit tricky.

 Given the width of the mesh and the amount of vertices to cover by the support radius, this script calculates an appropriate shape parameter for Gaussian basis-functions.
 The script also allows to specify a custom decay.
