Useful for interpolating unstructured data onto a grid?

Hey! Thanks for the interest and the short answer is not really... We support interpolation from a fixed grid to another one using the three closest points:
https://github.com/nicolas-chaulet/torch-points-kernels/blob/88dfbd542b1c4275012025c4b3708711ec0ce904/torch_points_kernels/torchpoints.py#L109 and https://github.com/nicolas-chaulet/torch-points-kernels/blob/88dfbd542b1c4275012025c4b3708711ec0ce904/torch_points_kernels/torchpoints.py#L40

But not the generic function kind of interpolation.

Thanks! Your package really did catch my eye! There are very few repos out there that do interpolation on the GPU, much less that do so on a point cloud!

If the package were at some point to include it, for instance as a function of some input Delaunay simplices/vertices grid, then I would really appreciate it if you dropped a message on this issue! I'm currently interpolating 10**7 points multiple times, and it's taking a little while :)

Unfortunately this is not planned at the moment, but feel free to contribute it if you want!
