The Voronoi pattern and various similar mathematical patterns can be surprisingly often seen in nature: on a giraffe’s body, a dragonfly’s wings, seed pods ... A huge number of Voronoi patterns and its variations in nature can be identified when seen through the microscope at the cellular level. All four Voronoi patterns that you can download here are drawn in Rhinoceros 3D CAD software using Grasshopper plug-in. The Voronoi pattern can also be applied to 3D surfaces; on page Topological mesh modeling examples, you can see and download (Voronoi sphere 3D model) for free a Voronoi pattern that is applied to a sphere in the form of opening.?
