Three-dimensional objects have height, width, and depth, like real-world objects that possess these three dimensions. For example, the human body is three-dimensional. Three-dimensional objects are also commonly referred to as 3D objects. In contrast, two-dimensional objects only have height and width.

4.  Having three dimensions such as
(height,width,and depth)
 Like any object in the real world.
 Example: your body is three-dimensional.
 Also known as “3D”.

1. 3d objects have
height,width,and
depth.
2. Objects in the real
world are 3-
dimensional, because
they have depth.
1. 2d objects only have
height and width.
2. Only create 2D
images.
