Mechanics-Aware Deformation of Yarn Pattern Geometry

How to read this

Category

Method: mechanics-aware yarn-level cloth geometry

Contributions

• Animates yarn-level cloth geometry on top of an underlying deforming triangle mesh in a mechanics-aware way
• Tiles precomputed yarn geometry per triangle in material space and uses triangle strains to drive a database lookup that applies the appropriate material displacement
• Reproduces yarn-scale effects such as knit loops tightening under stretch and runs in real time at large scales when combined with mesh simulation

Context

Extends yarn-level cloth modelling (e.g., Cirio et al.'s yarn-level simulation of woven cloth) by decoupling expensive yarn mechanics into a precomputed, strain-indexed displacement applied over a cheaper sheet simulation.Builds on: Yarn-Level Simulation of Woven Cloth

Correctness

The core assumption is that local yarn response can be captured by a strain-to-displacement database tiled per triangle; this trades full yarn-level dynamics for a data-driven approximation, so readers should expect it to capture characteristic deformations rather than exact contact-resolved yarn physics.

Clarity

Conceptually clear (geometry on a deforming mesh); a first pass conveys the tiling-plus-lookup idea, a second pass clarifies the material-space mapping and database construction.

How to read it

Focus on the precompute-then-lookup pipeline and the material-space tiling in pass one; a second pass on how strains index the database pays off if you care about reproducing the mechanics-aware detail.
