Here we have collected a couple of links which might be useful for people interested in polytopes. See also the list of programs which polymake interfaces to.

### General information about polytopes

- Komei Fukuda's's list of Frequently Asked Questions in Polyhedral Computation.
- David Bremner's PolytopeBase. Includes an annotated bibliography on vertex and facet enumeration, a collection of perl scripts producing polymake files of various classes of polytopes and a glossary.
- Jeff Erickson maintains a great site collecting information about Computational Geometry. Not restricted to polytopes, of course.

### Explicit constructions and descriptions of polytopes

- Oswin Aichholzer's page on 0/1-polytopes. You can obtain `polymake` files of low-dimensional 0/1-polytopes from there.
- Boris Springborn's Koebe realizations (edges tangent the unit sphere) of 3-polytopes with few vertices. You can also get `polymake` files.
- The Electronic Geometry Models archive. Among many other geometric objects you also find interesting polytopes.

### Visualization of polytopes

- George Hart's fantastic collection of Virtual Polyhedra. Plenty VRML files.
- Tim Lambert: Java applet visualizing a convex hull computation.
- Michael Gibb: 4d-visualization of a variety of polytopes, including stereoscopic views.
- More pictures of 4-polytopes at Wolfram Research.
- Bernd Sturmfels' and Josephine Yu's page on tight spans (or tropical simplices) of finite metric spaces with few points.

### More software

- qhull: a convex hull code based on floating point arithmetic.
- Marco Lübbecke's implementation of a convex hull code specialized on 0/1-polytopes: zeroone. Produces `polymake` output.
- Parma Polyhedra Library (PPL) - C++ library for the manipulation of rational convex polyhedra.
- Matthias Franz' Convex - a Maple package working with rational polyhedra and cones.
