Frustum4
Frustum projection projects higher dimensional object by making 'far' objects smaller.
This kind of projection is what most people recognize as what is 4D objects looks like.

Suitable Usage
Frustum may better suited for educational or visual purposes, despite it may be more complicated than cross section. However building model for frustum is easier because it does not deal with Tetrahedron as it's a game changer for cross section.
