Voronoi tessellation model of endfoot sheath. Top: a sample Voronoi tessellation with a mean endfoot area of $A=25\mathrm{\mu }{\text{m}}^2$ and a vessel radius of $r_{\text{o}}=10\mathrm{\mu }{\text{m}}^2$ (including endfoot sheath). Cell center positions are generated from a uniform random distribution. The tessellation is periodic which is important to ensure that wrapping around a vessel will provide a consistent tiling of the vessel surface. Bottom: same tessellation as above, but mapped onto a cylinder surface (vessel surface)
