Webin Python. In Matlab I can use the method 'spline' interpolation, which I can not find in python for 3D data. There exists scipy.interpolate.griddata, but it doesn't have the option spline for 3D data. The data I want to interpolate is a 3D matrix (51x51x51), which is regularly distributed on a 3D grid.
