Collection of discussions regarding volume, vertices, dissection, g-holed tori, and other subjects.
Comprehensive list of links to sites on geometric properties of the shapes.
Regular, rectified, and truncated polytopes with normal and hidden-detail-removed projections. Images, animations, and links.
Definitions, pictures, templates, and coordinates of the regular 3d and 4d polytopes. Also includes waterman polyhedra, polar and star spheres, and the time star.
Polytopes and optimal packing of p points in n dimensional spheres. Contains a java applet based on a model which allows for generation of multidimensional regular and semi-regular polytopes.
Enumeration, cartesian coordinates of vertices, naming, and counting the shapes.
Vertex figures, filling, faceting diagrams, stellation, defining polytopes through generators, trimethoric and trisynaptic polyhedra, space-filling polyhedra, lost stellations of the icosahedron, and links.
Derivation of volume equations for regular polygons, polyhedra, and polytopes, with images.
Educational toys used to teach geometry and model building to create squares, spheres, stars and other regular shapes with sticks and connecting pieces. Products include kits and lesson plans.
Three-dimensional objects constructed by slotting together a series of planar cross sections made from card. Downloadable templates in PDF, PS and Word formats.
