Commit 903ef27afcec7113390659935ae884798ed27188, 2026-10-13. MIT, Amanda Ghassaei.
Retains complete WebGL GPU dynamic physical solver, original mesh/beam/crease/node implementation, SVG crease parsing, FOLD conversion, triangulation and Three.js viewer controls. Seven locally bundled traditional/geometric crease patterns.
Modifications: new focused UI (studio.js/style.css/index.html), generated botanical washi texture mapped with persistent UVs to the moving paper surface, external shader data to comply with CSP, flat relative local paths, no analytics/upload/export/VR interfaces, constrained view resizing, lower solver steps for interactive performance, unsupported-WebGL cases raise a plain error shown in the panel (GPUMath.js), fold presets and PNG save of the current view (save.js). Unused dynamic template/numeric libraries replaced with direct each/uniq/matrix-vector helpers to avoid eval.
All corresponding preferred-form application source is in this directory; no build step. Dependencies retain their original notices and separate licenses listed in THIRD-PARTY.txt. No backend, account or external assets needed. GPU floating-point WebGL textures required. The physical solver does not prevent paper self-intersections.
