Surface scan of a Walrus skull from the D’Arcy Thompson Zoology Museum at the University of Dundee. Odobenus rosmarus - Walrus. DUNUC 2143. Brought back from the Arctic for D'Arcy Thompson by one of the Dundee whalers, c.1890s. Scanned with an Artec Eva surface scanner. The resulting file is exported as an obj. and imported into Zbrush. The texture is captured during the scanning process and converted to Polypaint in Zbrush. We’d love to hear from you if you download or print our models, especially if you use them in education and outreach.
