We derive an additive algorithm for the construction of such flat-sharable structures and demonstrate that it can design lattices which map to any quad-meshed surface including geometries with single and double curvature. We build a set of desktop-scale models using plastic sheeting and rivets to demonstrate our algorithm and a possible construction methodology for macro-scale architectures.
In addition, we note that pantograph lattices may be used as a platform for physical computing: as an example we construct a lattice of bistable nodes which can be reset using the collapsing mechanism.
