Those who work with PhotoShop are very familiar with 2D and 3D pictures, but i cannot differentiate these two types of pictures. I cannot find out a way of knowing it. Can anybody tell me how can i differentiate 2D pictures from 3D?
How to differentiate 2D and 3D pictures
HI!
2Dimensional refers to visual objects that are constructed on two planes (X and Y; width and height). Two-dimensional structures are used for 2D images. Examples of such images can be termed as “flat” and without perspective or depth.
3D adds the 'Z' dimension. This third dimension allows for rotation and depth. It's essentially the difference between a painting and a sculpture. 3D creates the illusion of depth as seen by the viewer. All forms of sculpture are done in 3D whereby it can be viewed from all sides. Even drawings are done in 3D as the “Z” dimension gives it the depth needed. Fonts too can be converted into 3D with the help of computer software’s.

2D is two dimensions in full. It is animation that doesn’t concentrate on producing images in projected depth. The image consists of only two dimensions that if you were to turn it to its sides it will form a straight line. In 2D shapes determine the length and width of the objects you are animating.
3D is three dimensions in full. In this kind of animation objects are created using an illusion whereby they use some techniques to manipulate depth. The third dimension permits r rotation and manipulation of depth. You can understand this better if you differentiate a sculpture and a painting. In 3D, the object has a realistic appearance which is achieved by manipulating depth and light.
This is why 3D images are more realistic to “cartoons “which are made using 2D.
How to differentiate 2D and 3D pictures
2D and 3D refer to the actual dimensions in a computer's workspace. 2D is 'flat', using the X & Y (horizontal and vertical) axis', the image has only two dimensions and if turned to the side becomes a line. 3D adds the 'Z' dimension. This third dimension allows for rotation and depth. It's essentially the difference between a painting and a sculpture.
Basically, you can only see 2 axis in a 2D picture which is the 'Y' axis and the 'X' axis while a 3D picture has 3 axis which is 'Y' , 'X' and 'Z'. Another example of 2D is a floor plan where you can only see 1 side of itself which the top view and an example of 3D is a house perspective of the floor plan where you can see more than 1 side of the house.
