Discrete Geometry for Mechanics

Desbrun et. al. 1999 left: Original 3D photograph mesh (41,000) vertices). right: Smoothed version with the scale-dependent operator in two integration step with $\lambda dt = 5 \cdot 10^{-5}$, the iterative linear solver (PBCG) converges in 10 iterations. All the images in this paper are flat-shaded to enhance the faceting effect.
