Shape a surface the way Gaudí and Frei Otto did — by letting it reach equilibrium. This is a full Kangaroo analog: build your own force system from a deck of 24 composable GOALS — anchors, springs, bending, hinges, gravity, wind, pressure, soap film, smoothing, planarization, on-geometry constraints, floor and sphere/mesh collisions, target volume — each gripping its own selection, each with a strength the solver negotiates by weighted projection. Ten presets are saved goal stacks (hang, soap film, fair, inflate, tent, drape, pack, planarize, arch, pillow); mix them, re-weight them, or start from an empty deck. Select vertices/edges/faces, drag, anchor, load — then export the form.
Runs entirely in your browser — three.js + rhino3dm vendored, nothing is uploaded, no account. Export the relaxed (or inverted compression) mesh as an OBJ for Rhino, or save a PNG. Form-finding only — not a sized structural design.
