Both 3D models have been modeled in Rhino 3D CAD software and its Grasshopper and T-Splines plug-ins. Use the Grasshopper plug-in to generate the Voronoi pattern and the Rhino 3D software and T-Splines plug-in to make the 3D structure. Only polygonal mesh 3D model in .obj file format is offered for download, as the files of these 3D models in NURBS 3D formats are very large.
