GitHub - xloveee/jiggle-physics: An open reference standard for jiggle physics: weight-painted regions + damped spring bones, one rule (vertex += weight * boneJiggle). Portable, dependency-free, WebGL demo included. By the xlovecam team.

▤ Summary

This release introduces an open reference standard for real-time jiggle physics built for portable use across engines and renderers. The project separates the simulation from the renderer, with a pure physics engine and a WebGL demo showing how to apply the standard. It uses weight-painted UV maps and damped spring bones to create consistent secondary motion on meshes. Developers can drop the engine into a game loop, sample weight textures, and drive vertex deformation with a simple contract. The repo also includes presets, a UV paint workflow, and attribution guidance for projects that adopt the standard.
