In the picture there is a 3D model that is called the ‘Genus 6 3D surface’ and offered for download here.
To MCAD (Mechanical Computer Aided Design) 3D software users this model may look complicated to draw, but using 3D graphics software that models with polygonal mesh, it can be created in a few minutes. We have used Blender and TopMod software to model, and 3D Rhinoceros software and its plug-in called T-splines to convert polygonal mesh to NURBS 3D model. If you have any idea how to use this strange 3D surface, feel free to download and use it. It has been well-modeled, as you can see, so it can serve as an initial 3D model for designing more complex math art bodies.
