End-to-end pipeline estimates shell-level cloth elasticity parameters from yarn stretch tests via extended homogenization matching.
Abstract
Virtual garment simulation has become increasingly important with applications in garment design and virtual try-on. However, reproducing garments faithfully remains a cumbersome process. We propose an end-to-end forward pipeline for estimating parameters of shell material models corresponding to real fabrics with minimal input. In contrast to prior work that relies on complex and often expensive capture systems, our method determines yarn model parameters from Young’s moduli determined during standard yarn stretch tests. We use an extended homogenization method to match yarn-level and shell-level hyperelastic energies with respect to a range of surface deformations represented by the first and second fundamental forms, including anisotropic bending. We optimize the parameters of a shell material model involving uncoupled bending and membrane energies. This allows the simulated shell model to exhibit deformation modes motivated by yarn-level physics in real fabrics. Finally, we validate our results with quantitative and visual comparisons against real world fabrics through stretch tests and drape experiments. Using the homogenized parameters, the shell models are capable of capturing the characteristics of underlying yarn patterns and exhibiting distinct behaviors for different yarn materials.

- Category
- Method: parameter estimation for cloth simulation
- Contributions
- An end-to-end forward pipeline that estimates shell-level cloth material parameters from minimal input (standard yarn stretch tests, Young's moduli).
- An extended homogenization that matches yarn-level and shell-level hyperelastic energies across surface deformations described by the first and second fundamental forms, including anisotropic bending.
- Optimizes a shell model with uncoupled bending and membrane energies so simulated cloth shows deformation modes motivated by real yarn-level physics.
- Context
- Builds on homogenized yarn-level cloth (Sperl et al., 'Homogenized Yarn-Level Cloth'), extending that homogenization idea to derive shell parameters from inexpensive yarn tests rather than full capture rigs.Builds on: Homogenized Yarn-Level Cloth
- Correctness
- Aimed at avoiding expensive capture systems by relying on standard yarn stretch tests; results are validated quantitatively and visually against real fabrics via stretch and drape experiments, so a reader should keep in mind it targets fabrics describable by yarn-level physics and the homogenization assumptions used.
- Clarity
- Reasonably accessible at the conceptual level; a first pass conveys the pipeline, but a second pass is needed for the homogenization and energy-matching formulation.
- How to read it
- First pass for the pipeline and where the inputs come from; do a focused second pass on the extended homogenization (fundamental forms, anisotropic bending, uncoupled energies) if you intend to reimplement or assess fidelity.
