Comment:

 Currently only linear interpolation is available in higher dim.

 The problem is basically that defining a C1 continuous spline runs into
 mathematical difficulties already in 3-D, and things get progressively
 worse as the dimension increases. So I think very few libraries (I'm not
 aware of any) implement anything more than linear in high-dim.

 Other options (that are way easier) that you can try to implement are
 radial basis functions, or inverse distance weighing based methods.
