if you want to sample points at the medial axis you could look at something like `coverage axis ++` which uses some really simple metrics to sample points at the medial axis without needing to do any kind of fusing/remeshing or advection.
But i will say the medial axis is inherently not as useful as the straight skeleton, cuz in 3d for many shapes its a surface and not a curve…
arxiv.org/abs/2401.12946 its a neat paper, a totally different approach for finding these surfaces. @mattiasmalmer @_white_dog_
if you want to get topology out of this and not just a point cloud it definitely takes more effort, and no one likes using effort
