Weekly Science Fair: Simulating Knitted Cloth at the Yarn Level

In Just Graduated on October 12, 2009 at 8:15 AM

From the Abstract: The properties of knits come from the nonlinear, three-dimensional kinematics of long, inter-looping yarns, and despite significant advances in cloth animation we still do not know how to simulate knitted fabric faithfully. Existing cloth simulators mainly adopt elastic-sheet mechanical models inspired by woven materials, focusing less on the model itself than on important simulation challenges such as efficiency, stability, and robustness. We define a new computational model for knits in terms of the motion of yarns, rather than the motion of a sheet. Movie Link.

Who: Jonathan Kaldor, Doug L. James, and Steve Marschner.

Real World Application: When Toy Story 8 comes around, following Woody and Buzz Lightyear as they go to the local Salvation Army resell it store, the second-hand sweaters and cardigans they’re thrown against will look so real you’ll think that you might have once owned the sweaters.
