Logarithmic maps are incredibly useful for algorithms on surfaces--they're local 2D coordinates centered at a given source. Yousuf Soliman and I found a better way to compute log maps w/ fast short-time heat flow in "The Affine Heat Method" presented @ SGP2025 today! 🧵

Many physical systems are high-dimensional, but we only really care about some low-dimensional subspace. Our latest work shows how to fit these subspaces as small neural maps automatically, *without* any data as input, just the energy function. Read on to learn how! (1/N) 🧵
