Ive had an initial go at something like this using JAX. I chose JAX since it has a shallow learning curve, essentially being numpy on a GPU. This is great for vectorized calculations, but less so for applications that involve a lot of control flow (ie if/else statements), which as i understand it most point cloud registration algorithms use, such as iterative closest point or anything available in open3d.
No guarantee ill make any progress of course, but would someone mind recommending a paper explaining a nice subshape alignment algorithm?
