4D Viewer

View 3D projections of uniform 4D polychora.  For more information about these shapes, see the Wikipedia page Uniform 4-polytope.  Use the dropdown at the top-right to choose a shape to view.  The left toolbar allows choosing rotation speed and moving the camera, and the right toolbar allows choosing the color of different sets of cells (including none, allowing hiding certain sets of cells) or hiding cells depending on whether they face toward or away from the +W axis.  The cell scale slider changes the size of cells and the projection slider varies from orthogonal to approximately-stereoscopic.

A newer version of 4D Viewer, with VR support as well as net unfolding and a greater variety of shapes, can be used freely online at DPH Software.
