Animators can develop more lifelike bouncy, stretchy, and squishy characters for films and video games, thanks to an innovative simulation technique formulated by researchers at MIT.

This strategy enables animators to replicate rubbery and elastic materials while preserving the material’s physical traits and circumventing issues such as instability.

The method mimics elastic objects for animation and various uses, boasting enhanced reliability in comparison to alternative techniques. Many existing simulation methods can yield elastic animations that become unpredictable or sluggish, or may even collapse entirely.

To realize this enhancement, the MIT researchers unveiled a concealed mathematical framework in equations that depict how elastic materials deform on a computer. By utilizing this characteristic, referred to as convexity, they established a technique that consistently delivers precise, physically accurate simulations.
