Robust Treatment of Collisions, Contact and Friction for Cloth Animation

How to read this

Category

Method: cloth collision, contact and friction

Contributions

• A robust algorithm combining geometric collision detection with repulsion forces for cloth
• Modeling of cloth thickness and prevention of self-intersection
• Coulomb-style friction modeling that produces realistic folds and wrinkles

Context

Builds on Baraff and Witkin's Large Steps in Cloth Simulation, supplying the collision, contact, and friction treatment that the dynamics solver needs for believable folding.Builds on: Large Steps in Cloth Simulation

Correctness

Validated by realistic, self-intersection-free folds and wrinkles; reader caveat is that the results depend on the repulsion-plus-geometric-detection combination and the friction model, with the usual cost and tuning concerns under heavy self-contact.

Clarity

Accessible; a first pass conveys the repulsion-plus-collision idea, a second pass clarifies the friction and self-intersection handling.

How to read it

Focus on how repulsion forces and geometric detection cooperate and how friction yields folds; a second pass is worth it for the contact-resolution mechanics. Note this overlaps closely with the companion robust-cloth entry.
