Sculptable Mesh Structures for Large-Scale Form-Finding
summary
A room-scale sculptable mesh is built from adjustable beams that tuck excess FR4 strips under the surface and sense extension with resistive length sensors (pogo-pin probes on staggered copper pads), forming T modules that wire into a winged-edge mesh. Lengths feed a two-stage solver (coarse vertex lengths, fine bending and coplanarity energies) to reconstruct a CAD-ready surface (benches, overhangs demonstrated). Prototype works for hand-sculpting but cannot self-actuate yet; modules can be miniaturized.
