The polynomials in the code aren't used as blending functions, it's a piecewise cubic interpolator ... they are used as a convolution kernel (a non C1 continuous convolution kernel).

This whole methodology seems a weird mishmash of disparate theories to me, there is a rhyme to it ... but very little reason.
