4D Euclidean space
31 Dec 2008: Tweak the rendering settings of the 120-cell perspective projection so that the image is clearer. Also reduced the edge radius of all the projections; they should look nicer now.
29 Dec 2008: Added the runcinated tesseract, the 4D analogue of the rhombicuboctahedron.
27 Dec 2008: Added the bitruncated tesseract, a uniform polychoron bounded by 8 truncated octahedra and 8 truncated tetrahedra.
26 Dec 2008: Added the truncated 5-cell, a uniform polychoron bounded by 5 tetrahedra and 5 truncated tetrahedra.
21 Dec 2008:
Added Cartesian coordinates to the bitruncated 24-cell.
Fixed some XHTML and CSS compliance errors. Standards are important!
15 Dec 2008: added the Omnitruncated 24-cell, a beautifully intricate polychoron bounded by 48 great rhombicuboctahedra and 192 hexagonal prisms.
8 Dec 2008:
6 Dec 2008: Replaced old XFig figures of the cubical pyramid with POVRay-rendered versions.
4 Dec 2008:
3 Dec 2008: Several updates:
2 Dec 2008: Replaced XFig figures of the cubical cylinder with much nicer POVRay-rendered versions. The description has also been updated, and more projections have been added.
26 Nov 2008: Replaced XFig figures in chapter 6 of the 4D visualization document with POVRay-rendered images. Only one more chapter to go!
24 Nov 2008:
1 Nov 2008: These pages are undergoing a major face-lift and reorganization:
A new navigation bar has been added for ease of navigation.
The old XFig diagrams are gradually being replaced with POVRay-rendered images. This is still a work in progress; currently, the regular polychora and parts of the 4D visualization document have been updated. More are on the way!
Nice backgrounds made with a new polytope projector that renders projections using POVRay.
