extend to 2d #15

hi @aliutkus thanks for sharing the wonderful work, I'm wondering how to extend the function to 2d points?

Hi, thanks for your interest. Good question, yes I guess it's feasible, and requires some multidimensionnel generalization to searchsorted. The common way is to use Delaunay triangulation. Both matlab and scipy have this. See for instance https://docs.scipy.org/doc/scipy/reference/generated/scipy.interpolate.LinearNDInterpolator.html#scipy.interpolate.LinearNDInterpolator It would basically mean porting that code to torch...

Did anyone ended-up working on this? Seems like a cool idea.
