Homogenized Yarn-Level Cloth

How to read this

Category

Method: numerical homogenization for cloth simulation

Contributions

• Animates yarn-level cloth effects using a thin-shell solver via numerical homogenization
• Builds a potential-energy-density model from many yarn-level simulations, then computes shell forces from it
• Provides data-driven models of several woven and knitted fabrics, derived purely from simulation with no real-world measurements

Context

Bridges yarn-level cloth simulation (in the tradition of Kaldor et al.'s yarn-level knitted cloth) and continuum thin-shell solvers through homogenization.Builds on: Simulating Knitted Cloth at the Yarn Level

Correctness

The fidelity rests on the assumption that an energy-density function fit to yarn-level simulations captures the relevant mechanics in a shell model; because it is calibrated to simulations rather than physical experiments, accuracy is relative to the underlying yarn model and effects beyond that model's scope may not transfer.

Clarity

Conceptually clear on a first pass; the homogenization and energy-density fitting need a careful second pass.

How to read it

First pass for the homogenization idea (yarn sims to a shell energy); second and possibly third pass on the energy-density construction and force derivation if implementing or extending the material model.
