This and Miegekure show cross-sections or projections of a 4d space that are common but that show details that could not possibly be seen by functional 4D eyes.

This and Miegekure show cross-sections or projections of a 4d space that are common but that show details that could not possibly be seen by functional 4D eyes. Are there any attempts out there at showing a 3D representation of what 4D eyes could see? (For example, if you have a solid 4D cube, you can only see the outside of it, but the cross-section shows parts of the inside, as happens you take 2D cross-sections of a 3D cube)
