Useful references to prior art and good context.

Maybe it was not polite of him to dismiss the blog post (and maybe that wasn't his intention), but I do appreciate that he provided references to prior art, and also took the…
nicklaf on HNI also appreciate the provided references.

Good expository writing on variational calculus.
From 1 comment
Yea I really liked your post because of that focus. I use variation all calculus quite a lot for non-programming stuff and it’s really allowed me to understand things like NNs…

Not novel; smooth hole filling with polynomials and curves has existed for decades.
From 1 comment
This is sort of neat but not really useful and not novel. The reason it isn't novel is that people have been smoothly filling holes via various polynomials and other smooth…

Real scanner data needs volumetric best-fit, not a surface-only fix.

Globally changes the whole mesh, which can lose detail.
From 1 comment
For visualization or maybe 3D printing, yea. But for finite element analysis, you don't want smooth filling at weird corners/etc. A flat surface is more efficient since it can…

Can the refinement and unrefinement steps be avoided?

MeshFix implements similar hole filling.

Nice explanation. I think meshfix implements this too: https://github.com/MarcoAttene/MeshFix-V2.1

Radial basis function implicit surfaces.

I did almost the same thing in a very different way as part of my PhD research: https://imgur.com/a/k6AQi I did it by representing the surface implicitly with radial basis…
