Are there any good libraries for solving cubic splines in C++?

Question

Hello everyone,

I'm looking for a good C++ library to give me functions to solve for large cubic splines (on the order of 1000 points) anyone know one?

Thanks in advance,

-Faken

Answer 1

Try the Cubic B-Spline library:

• http://www.eol.ucar.edu/~granger/bspline/doc/

and ALGLIB:

Answer 2

Take a look at David Eberly's GeometricTools.com. I'm just starting, but code and doc are so far of outstanding quality.
(He has books too: Geometric tools for computer graphics, 3D game engine design.)
