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 x-axis but in the cartesian distance of two points. Means the new points set have the equal distance interval between adjacent points.

Thanks.

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).
