4D VR
View and interact with 4D objects, higher-dimensional geometry, and hyperbolic and spherical space.
4D objects are shown as 3D cross-sections, and you can move the cross-section along
the fourth axis, w.
1 Hyperplay 4D physics sandbox
2 Polytope Lab Regular 4-polytopes, projected and sliced
3 Knot Lab Untie knots by moving strands through w
4 Hopf Garden The Hopf fibration of the 3-sphere
5 Hyperbolic Space The {5,3,4} and {4,3,5} honeycombs
6 Spherical Space Walk inside the 120-cell on the 3-sphere
7 Klein Room Walk through a wall and come back mirrored
8 Quasicrystals Slices of 5D and 6D lattices that never repeat
