@anisomorphism Theory: heat kernel behavior <=> stochastic processes, geodesics, transport, curvature... Algorithms: heat methods for geodesic distance, diffusion maps, functional maps, spectral methods for shape analysis more generally, etc. And neural variants used in e.g. manifold learning.

A similar story has played out in some geometry processing algorithms, including our recent paper on robust SDFs: Saw Iolo's work at SoCG, and looking forward to taking a deeper dive into this new paper.
Signed distance functions (SDFs) are fundamental tools in graphics, vision, and physics simulation. But how do you get a high-quality SDF from messy, real-world input? At #SIGGRAPH2024, we introduced a simple method for turning "broken" geometry into a well-behaved SDF. <🧵>

@amirvaxman_dgp @yotam_erel The SHM also requires your points to be (mostly) oriented, not sure yet how to best extend to unoriented data. Could use the shrink-wrapping methods Bruno mentioned, which should work well for densely sampled point clouds that approximate your surfaces well.

@BattleAxeVR You could pre-compute some "simplified" surfaces along the lines of this example. Not entirely sure yet how to do this "on the fly"/continuously, but working on it. Maybe something like Hoppe's "progressive meshes" is more appropriate?

@danbri Haven't tried gaussian splats, but in principle the method should work as you have normals for the geometry - which for gaussians might be done by taking a gradient where you've deemed your zero level set surface to be. Might be some finicky details to figure out.

FYI shoutout to Chris Yu and Nick Sharp (@nmwsharp) for developing the awesome volume grid/tet visualization features in Polyscope.
