Point dimensions

[resema]

Hey Marcel

Just a small question =)

I'd like to pass points with 4 dimensions of informations, such as points in 3-dimensional space and a velocity at the control points. Is it possible to interpolate all 4 dimensions, and are there priorities set by the algorithm?

Best regards,
Renato

I think you should be able to interpolate the desired function by setting up your control point array as follows: [x0, y0, z0, v0, x1, y1, z1, v1, ..., xn, yn, zn, vn] with x, y, z being a coordinate in 3D and v being the corresponding velocity. Pass the array to ts_bspline_interpolate and see what happens :) (in this example dim has to be 4 and n the length of your array.). However, since v simply is another kind of dimension, ts_bspline_interpolate should give you a valid result, though, I'm not entirely sure.

I have to mention that, currently, ts_bspline_interpolate always creates natural splines (should fit your case). Further types will be add in future, see #39.
