The 3D model that you can download here is based on a mathematical surface called the ‘Clifford torus’ by making simple manipulations in 3D software.

This is a typical example of how complex 3D shapes can be easily obtained. With MathMod (former K3DSurf) software, we generated a Clifford torus 3D model and exported it in .obj format. Then we imported the 3D model so obtained into TopMod software, in which we deleted one half of it (Clifford torus 3D surface – Version 2) and added thickness to the 3D model. On the body thus obtained, we deleted certain faces to make holes, and transformed some of the faces into bulges. The whole modeling process took us a maximum of 15 minutes, and the result, at least by our standards, is not bad at all!
