Four-Space Visualization of 4D Objects
Mathematical and computer programming oriented approach. Discusses wireframe rendering and ray-tracing.
Fourth Dimension: Tetraspace
A discussion of rotation, levitation, wheels, and bodies of water. Classification of "rotatopes" (cubes, spheres, and cylinders), and a Java applet to visualize projections and intersections of the shapes. Includes book reviews, a glossary, links, and a forum.
The 4D Web Page
List of links to sites on people, books, art, java applets, games, and general information on the fourth dimension.
Hypercube's homepage
Philosophy, math, and cosmology related to the fourth dimension.
Miscellaneous Mathematical Musings
Introduction to dimensions, multi-dimensional geometric units, and formulas for calculating higher-dimensional phenomena.
Thinking 4-d
Focuses on helping the reader to conceive of the fourth spatial dimension, and in particular discusses hypercubes and hyperspheres.
Hyper Dimensia
Tutorial which aims to give readers an understanding of the fourth dimension by having them use a java applet to rotate a cube and a hypercube to see multiple views of the shapes at once.
Hyperspace Travel
Images and animations of a couple of four-dimensional objects, along with the math and source code used to produce them. Links to software to interactively visualize four-dimensional objects.
Hyperspace Structures - Exploring the Fourth Dimension
Introduction to the hypercube, hyper-torus, and approximation to the hypersphere. Page includes Mpeg movie clips to illustration the various objects.
HyperCube by Harmen
A short introduction to the fourth dimension, plus a hypercube java applet game.
