I just noticed this post (catching up on my reading oldest-first...) so excuse me if this has already been taken further.
As the curator of Interpolations.jl (Grid.jl's 0.4 successor) I would be happy to join efforts toward creating a single, powerful collection of tools. Interpolations.jl currently only supports b-splines, but I have envisioned it as the goto package for any interpolation-related functionality. If you hadn't heard of Interpolations.jl before it's not too surprising - I haven't yet tagged a version, mainly because I want to resolve vector-valued evaluation first (there's an open issue, but I'm on mobile so linking is difficult). I'm hoping to be able to get that ready as soon as I have a couple of hours to spend on it, if no-one else gets to it before I do. If you do want to join forces, maybe you could file an issue or a PR so we can hammer out the details? :) You'll find everything at github.com/tlycken/Interpolations.jl Best regards, Tomas
