A simplex is an n-dimensional polytope with n+1 faces and n+1 vertices.
Simplices are special because they are always convex and are never self-intersecting. Any polytope can also be built out of simplices of its own dimension. For these reasons, simplices are often used as "building blocks" in CGI.
Simplices are all also self-duals. The only other regular polytope to exhibit this behavior, bar 2D shapes, is the icositetrachoron in 4D.
