Possible extensions of the CE model. (a) Cell reconstruction with the help of hidden edges. Black solid lines filled with grey shade represent SE components and dashed lines depict hidden edges. (b) Cell reconstruction for different functions of the CEs. Two dashed purple circles represent edges with zero curvature, and two purple lines show two SEs forming a line similar to deformation type C in figure 3. (c) A single-cell example with a singular point. (d) The three-dimensional representation using the bounded spherical balloon equation in [61]. The singular boundary point is ignored in the calculation.
