Here you can download three 3D figures created on the basis of 3D models of infinite loop 3D surface.

All the 3D models were created in TopMod software. The Infinite loop was modeled according to an online tutorial. With TopMod software, the resulting model was easily transformed into interesting 3D models that you can see in the picture. We don't really have a clue how you could use these 3D models, but if anyone does, feel free to download and use them as you please. By the way, modeling of all three models in TopMod software will take no more than 15 minutes.


Shapes based on 3D loop surface
3D CAD software used for modeling


- Topmod for modeling

- Rhino 3D and T-splines plug-in for conversion to NURBS 3D surfaces

Available NURBS and BREP file formats

Surface 3D model - .igs (Initial Graphics Exchange Specification)

Available polygonal mesh file formats


Geometry: Mesh - Quads only; Mesh topology supports multiple subdivisions; Base 3D model without texture and materials; Mesh does not have any degenerate faces, non manifold edges, naked edges, duplicate faces...


The 3D model in the upper left corner converted to NURBS format is very large, so we haven’t made it available. If you are interested in drawing such strange 3D models, there are high-quality online tutorials for various free 3D graphics programs such as Blender, TopMod, Wings3D etc.
