Fine Wrinkling on Coarsely Meshed Thin Shells

We propose a new model and algorithm to capture the high-definition statics of thin shells via coarse meshes. This predicts global, fine-scale wrinkling at frequencies much higher than resolution mesh; moreover, it is grounded in geometric analysis elasticity, does not require manual guidance, corpus training examples, nor tuning ad hoc parameters. first approximate shape shell using tension field theory, which material forces do resist compression. then augment this base mesh with wrinkles, parameterized by an amplitude phase that we solve for over mesh, together characterize geometry wrinkles. validate our approach against both physical experiments numerical simulations, show produces wrinkles qualitatively similar those predicted traditional solvers requiring orders magnitude more degrees freedom.
