this page presents interactive 3D models I made for my research on geometry, which are also available on my sketchfab page.
daniel barbaro’s convex non-uniform polyhedra
the captions for these models refer to the descriptions and figure numbering in Daniele Barbaro’s La Pratica della Perspettiva (1568) and draw on my studies of his non‑uniform polyhedra, including the paper “Materializing Daniele Barbaro’s Creativity with 3D Printing” and the chapter “Non‑Uniform Polyhedra Described by Daniele Barbaro”.
campanus sphere
the captions for the Campanus sphere models refer to Euclid’s Elements, book XII, proposition 17, and follow the construction described on this page.
dual polyhedra
this 3D model for the dual polyhedra refer to the constructions and notation presented on this page on dual pairs.
concave semiregular polyhedra
this 3D model for a concave semiregular polyhedron follow the definitions and constructions outlined on this page.
concave quasiregular polyhedra
the 3D model for the concave quasiregular polyhedra follow the definitions and constructions outlined on this page.
expansion of polyhedra
the 3D model for the expansion of the edges of polyhedra follow the definitions and constructions outlined on this page.
