Yarn-Level Simulation of Woven Cloth

How to read this

Category

Method: yarn-level simulation of woven cloth

Contributions

• A discretization of interlaced yarns based on yarn crossings and yarn sliding that models yarn-yarn contact implicitly, avoiding explicit contact handling at crossings
• Internal yarn force and inter-yarn frictional contact models combined with this discretization
• A massively parallel solver enabling woven garments with hundreds of thousands of yarn crossings at practical frame rates on a desktop

Context

Extends yarn-level cloth simulation, following 'Simulating Knitted Cloth at the Yarn Level', from knits toward woven fabrics with a tractable contact treatment.Builds on: Simulating Knitted Cloth at the Yarn Level

Correctness

The key assumption is that yarn-yarn contact at crossings can be encoded implicitly by the crossing-and-sliding discretization rather than resolved explicitly, which is what makes realistic yarn densities tractable; demonstrated on woven garments, so applicability is strongest for woven structures and rests on the elastic-rod and friction models chosen.

Clarity

Fairly technical; a first pass conveys the crossing-based idea, a second pass is needed for the discretization and contact formulation.

How to read it

First pass to grasp why implicit crossing contact makes yarn-level weaving feasible; do a careful second pass on the crossing-and-sliding discretization and the friction model, and a third on the parallel solver for implementation.
