The main principle is that all Newsec graphics should be treated as two-dimensional, i.e without depth (to the objects). This goes for typeface, logos, graphs and icons alike.
While Newsec graphics as such have no depth, they may be positioned in a 2D or 3D environment to allow for perspective and parallax effects. In its most simple form this includes compositing on top of a still photo, 3D still render or video footage. A more advanced approach is to place the 2D objects in a 3D-environment. This may include compositing motion-tracked graphics in live action footage or in a 3D-rendered environment.
