Hypercube (Rhombic Dodecahedron Envelope) What you will find on the links from this page are a series of computer generated projections of the 6 regular polyhedra that exist in 4-space.

Hyperspace, in this context, means a Euclidean space of more than 3 dimensions.  If you ask, "Can I stand in my office and point in the direction of the 4th dimension?"  No, but I am fascinated by the possibility of visualizing something which is so foreign to my experience.  The projection of 4-space figures into 3 space, is a natural extension of my desire to understand 3-space.

I was introduced to Hyperspace by David Brisson, a Professor at RISD.  David was convinced that he could visualize n-dimensional space.

The following pages depict the 6 regular figures in 4-space

Hypercube analog of the cube. Hypercube Sections. Hypercube Envelopes.
Simplex analog of the tetrahedron. Simplex Envelopes.
Cross Polytope analog of the Octahedron. 16-Cell Envelopes
24-cell a figure without direct analog in lower or higher spaces. 24-Cell Envelopes
120-Cell analog of the Dodecahedron. 120-Cell Envelope
600-Cell analog of the Icosahedron. 600-Cell Envelope

Some other Hyperspace sites:

4-Space Rotation Java applett that rotates 4-space figures.
Flatland A charming book introducing the subject.
Geometry Junkyard Some heavy duty thoughts on this subject.
