Accurate Anisotropic Bending Stiffness on Particle Grids

Combining the accuracy of continuum surface mechanics with the versatility of particle systems, we propose a very simple and fast mechanical model for representing bending elasticity in surfaces. This model, formulated as a grid particle system, simulates accurately bending elasticity, and offers very good computational efficiency through a very simple and completely linear formulation. We demonstrate its accuracy and efficiency through quantitative comparative tests.
