Da Vinci tetrahedron and Jenn 3D tool for visualizing Coxeter polytopes

Above left: Leonardo da Vinci supplied two views: a plane view and an empty view where he removes the sides to reveal the complete structure of the tetrahedron. Above right: a tetrahedron was created using computer program Jenn 3D.

Leonardo da Vinci (1452-1519) was a great lover of geometry. His most outstanding polyhedral accomplishment is the illustrations for Luca Pacioli's 1509 book The Divine Proportion.
