Harmonic Extension
A classical interpolation method in mesh signal processing that fills in displacement values at unobserved vertices by solving the Laplace equation. It requires no training and produces smooth results, but cannot express high-frequency motion detail.
Timeline (last 90 days)
Cepheid's unified model surpasses harmonic extension on all evaluated geometric families, including previously unseen cloth and legged bodies, and does not require skeletons, registration, or cross-mesh correspondences.
Harmonic extension fills in the displacement values of unobserved vertices by solving the Laplace equation Δf = 0; it requires no training, is computationally efficient, and produces smooth results, but it yields overly smooth results and cannot express high-frequency motion details.
