-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi everyone,
I am seeking help on understanding the concept that GML is defining for cubic splines. I am involved in writing an interpolation algorithm in the deegree software that returns points on a cubic spline. Firstly, I have been looking at the GML definition of cubic splines and wondering how to interpret it. There, a cubic spline consist of control points and starting and ending tangent vectors. It appears as the piecewise cubic polynomials (that are defined mathematically for a cubic spline) can be deduced from the two tangents, but how does one do that? Or is the target of the GML type not one of defining a rigorous math object? Apart from that however, I would also like to ask if someone from GeoTools has stumbled upon a discrete algorithm for interpolating cubic splines, or at least can give me some literature references. Thanks for your attention. Any answers related to this subject will surely be of help.
