WebGPU Pineapple Jelly Ring Soft-Body Simulation

A pineapple jelly ring soft-body simulation written by hand in WebGPU and WGSL, built on an XPBD tetrahedral mesh. You can grab the outer or inner edge, stretch it, flip it over, and let it wobble. It includes refraction, absorption and fibre detail, plus a materials-research-style UI. The prompt is a highly specialised long spec that details the mesh, physics and rendering pipeline parameters. Suited to graphics tech demos or demanding model capability tests.
