  text: 'Bending-active structures are able to efficiently produce complex curved
    shapes starting from flat panels. The desired deformation of the panels derives
    from the proper selection of their elastic properties. Optimized panels, called
    FlexMaps, are designed such that, once they are bent and assembled, the resulting
    static equilibrium configuration matches a desired input 3D shape. The FlexMaps
    elastic properties are controlled by locally varying spiraling geometric mesostructures,
    which are optimized in size and shape to match the global curvature (i.e., bending
    requests) of the target shape. The design pipeline starts from a quad mesh representing
    the input 3D shape, which defines the edge size and the total amount of spirals:
    every quad will embed one spiral. Then, an optimization algorithm tunes the geometry
    of the spirals by using a simplified pre-computed rod model. This rod model is
    derived from a non-linear regression algorithm which approximates the non-linear
    behavior of solid FEM spiral models subject to hundreds of load combinations.
    This innovative pipeline has been applied to the project of a lightweight plywood
    pavilion named FlexMaps Pavilion, which is a single-layer piecewise twisted arc
    that fits a bounding box of 3.90x3.96x3.25 meters.'
