Nautilus Shell (sectioned)

3D Model

Micro CT scan of a half section of a nautilus shell from the D’Arcy Thompson Zoology Museum at the University of Dundee.

As an elegant demonstration of the logarithmic or equiangular spiral in nature, the nautilus is perhaps the most iconic image associated with D’Arcy Thompson’s ground-breaking work in mathematical biology.

Scanned with a Nikon XT H 225ST micro CT scanner. The resulting file is exported as an stl. and imported in to Zbrush. Texture is added from photographs using the Spotlight function and Polypainting.

We’d love to hear from you if you download or print our models, especially if you use them in education and outreach.
