2D and 3D: The term “three-dimensional” also is sometimes used to describe a physical item such as a sculpture or mobile, which could be described as three-dimensional art, in comparison with a two-dimensional painting.
The 2D graphics, as the name implies, are graphics that only deal with two-dimensional space while 3D images add the perception of depth.
2D and 3D
2D refers to the term “two-dimensional.” A 2D image has only height and width.
3D refers to the term “three-dimensional.” A 3D object has 3 dimensions which include length, breadth, and height.
Aspects of 2D and 3D
A 2D shape is a figure that has only length and height as its dimensions. Because 2D shapes lie on a flat surface, they are also known as plane figures or plane shapes. While they have areas, 2D shapes have no volume.
2D images are flat images that we normally see on our smartphones or draw on paper. They can be represented on a plain sheet of paper or on our plane smartphone screen. Apart from length and height, a 3D shape also has width or depth as its third dimension.
Whereas, a 3D figure is plotted on three axes, namely the x-, y-, and z-axes.
Examples
Circle, triangle, square, rectangle, and pentagon are some of the most common examples of 2D shapes.
Cylinder, pyramid, cube, and prism are some of the most common examples of 3D shapes.
Distinctions Two Dimension and Three Dimension.
1. In 2D shapes, only 2 dimensions are there are X and Y. While 3D shapes have three dimensions: X, Y, and Z.
2. 2D is used to construct a square, circle, triangle, rectangle, hexagon, etcetera.
3. 2D involves length and breadth, while 3D comprises length, breadth, and height.
4. 3D is used to achieve isometric and orthogonal shapes.
5. There is relatively more ease in constructing 2D than 3D.
6. Generally, 2D images are completely visible in the drawings while 3D shapes are not visible or hidden due to overlapping.
