Fig. 5: Inverse design of 3D shapes.
From: Boundary curvature guided programmable shape-morphing kirigami sheets
a Flow diagram of the inverse design. b Schematic of using curves to approximate and represent the target shape (side view of a waterdrop). The inset shows an isometric view. Red, orange, and yellow curves are the boundary curve \(\varGamma\), geodesic curve G, and backbone curve \(B\), respectively. c Experimental inverse-design result of the waterdrop shape formed by a 2D kirigami precursor subject to uniaxial tension. The yellow curve is the backbone in the target shape. d Schematic of using curves to approximate and represent the target shape (side view of a vase), with an isometric view showing in the inset. e Experimental inverse-design result of the vase shape formed by a 2D precursor subject to uniaxial tension. Scale bars = 10 mm.
