General Interest:Models

Here are designs you can use for making 3-D models out of, say, paper.

Globes

These polyhedral globes carry (somewhat out of date) maps of the Earth; they were originally designed for the Building a New World project in May of 1993, where a 1:1000000th-scale (12 meter tall) globe was assembled from metal struts and painted plastic tiles on the University of Minnesota campus.

That summer, the Geometry Center's annual Summer Institute topic was computational geometry, and Brad Barber and Stuart Levy made similar maps in sizes suitable for printing on paper or cutting from cloth.

Here they are. All sizes assume the designs are printed on 8.5x11-inch paper.

PDF 2.4MB or ZIP of same PDF (700KB) of a regular icosahedral globe:
twenty triangles forming a 32-centimeter world
PDF (3.1MB) or ZIP (940KB) of 50 triangles forming a 50-centimeter world
PDF (1.8MB) or ZIP (1.8MB) of 80 triangles forming a 66-centimeter world
PDF (2.6MB) or ZIP (2.5MB) of 124 triangles forming a 90-centimeter world, just under 3 feet across

Anyone is welcome to reproduce these patterns for personal or educational use. -- Stuart Levy
