This is 4D Polytope Viewer written by typescript and three.js. You can see most 4D convex uniform polytopes and rotate them.

1. Go to here.
2. Push the "View" button.

Then you will see a rotating 4D cube.

By pushing buttons in the "Control" section, you can change the control mode.

• Auto: It rotates automatically.
• Stop: It stops.
• 3D move: You can rotate in three-dimensional space by dragging the mouse.
• 4D move: You can rotate in four-dimensional space by dragging the mouse.

1. Select a polytope class from the drop-down list on the left.
2. Select a polytope from the drop-down list on the right.
3. Push the "View" button.

Then you will see the polytope.

If you check the checkbox of "Frame" and press the "View" button, the polytope will be displayed in frame mode.

Wikipedia page Uniform 4-polytope includes a nice explanation. The name of polytopes in "**-cell series" in this app are based on Coxeter diagrams. 0 in this app corresponds to ● in the Coxeter diagram and 1 corresponds to ◉. Thus, for example, 0101 in this app corresponds to Coxeter diagram ●－◉－●－◉. "Snub" in this app corresponds to ◯－◯－◯－◯.
