What constraints are involved in working within a 3D
environment - polygon count, file size and rendering time?
3D takes up far more resources than something 2D.
A 2D box takes up 4 edges, an extremely low poly 3D box takes up at-least 12 edges, 3x as many. All 2D shapes also have one face, while our low poly 3D box would have 6 faces minimum, which is 6x more.
More polygons means a larger file size, which makes storing the project more difficult, and also means a longer rendering time, which leaves you unable to properly use the computer for longer periods as it's using most/all of it's power to render.
Rendering time is possibly the most important issue to deal with as no one can use the computer that is rendering until the rendering is finished and saved which can be a real hassle when there is a full class who need all the computers.
