Post subject:  Resample a spline at equidistance 
Hi, I have a set of points (x[], y[]) and used Spline1DBuildCubic() to interpolate them to a cubic spline. Question is how can I resample this generated spline at equidistance? Equidistance is not in xaxis but in the cartesian distance of two points. Means the new points set have the equal distance interval between adjacent points. Thanks. Ethan

The only solution I have so far is to start from the left node (the boundary point) and manually calculate "next" point (try some trial distance along X, increase/decrease it until required precision is found).
