celshaded ko phải là tất cả đều là nhân vật 2D trên nền 3D nhưng có nhiều trò như vậy còn Soma Bringer nhân vật 3D trên phông nên là 2D(vì thế khi zoom lại mới bị vỡ pixel). Copy đoạn wiki cho cậu:
2.5D (two-and-a-half-dimensional) is an informal term used to describe visual phenomena which is actually 2D with 3D looking graphics. This is often also called pseudo-3D.
The term is usually used with computer graphics, especially video games, where a computer system uses 2D computer graphics to visually simulate 3D computer graphics. One such method is where a 2D image has an added "depth" channel or Z-buffer which may act like a height map. The term is also used to describe 3D scenes built completely or partially from a composite of flat 2D images; and also where gameplay is restricted to a 2D plane while the display uses 3D graphics and 3D models.
While the term is largely restricted to computer graphics, especially video games, it has also been used to describe visual perception, especially stereoscopic vision, which may be considered 2.5D because the 3D environment of the observer is projected onto the 2D planes of the retinas, which, while effectively 2D, still allow for depth perception.
