Nope, you're correct.

There are two main ways to transform a 4D object into something that our 
3D senses can comprehend. One is to take a 3D slice out of the object 
(which can obviously be done at different angles, and through different 
points). The other is a "projection", rather like the way POV-Ray 
transforms 3D scenes into 2D images. Like POV-Ray, you can do this two 
ways - a perspective projection, and an orthographic projection.

Fun fact: If you slice off one corner of a cube, the new facet is 
triangular. Similarly, if you slice off the corner of a hypercube, you 
get a tetrahedron...
