The position of the upper vesicle perimeter is intentionally aligned along the x-axis (z=0). The figure shows the right side of each cross section, and the initial shape is also shown by the broken line.

Three-dimensional membrane contours of the computed equilibrium configurations in the case of spontaneous radii ratio n=10 and shear modulus μ=0.66×10−2dyn∕cm. They were drawn by using Mathematica . The meshes in the figure were automatically generated by Mathematica so as to show three-dimensional images effectively.
