However that is the point in analysis of the spline resampling coefficients. I.e. are the coefficients good enough for video resampling purposes or shall we tweak them to get better results for our case?
For instance, that 360degree rotation test has little relevance to madshi render, as we only do single resampling. for instance, in this case we can allow some oversharpening provided other artifacts are tolerable.
@willbert:
My contact implies you made a mistake when calculating spline64 coefficients.
His solution in Maple:

compare to the original equations in the code:

Only 4 equations have been calculated, as others are symmetrical.
