What is the difference between 2D and 3D?

I. Definitions:

1. 3D:

Refers to three dimensions, three dimensions, three coordinates, that is, there is length, width and height. In other words, it is three-dimensional, 3D is the concept of space is also composed of X, Y, Z three axes of space, is relative to only length and width of the plane (2D).

2, 2D:

Also known as planar graphics, 2D graphics content is only horizontal X-axis and vertical Y-axis.

Two, performance:

1, 3D:

Computer, the Internet's digitized 3D/three-dimensional/stereoscopic technology, 3D film stereoscopic effects.

2, 2D:

Flat animation, handmade cartoons, illustrations, etc..

Expanded Information

3D or three-dimensional digitization technology, is a modern tool-based basic ****use technology based on computer/network/digital platforms, including the development of 3D software development technology, 3D hardware development technology, as well as the combination of 3D software, 3D hardware and other software and hardware digitization platforms/devices in the different industries and different needs.

According to scientific conjecture, people originally lived in four-dimensional three-dimensional space (plus a time dimension), the eyes and the body perceived the world are three-dimensional, and has a rich color, luster, surface, material and so on the appearance of texture, as well as ingenious and intricate internal structure and space-time dynamics of the movement of the relationship between the world; we are the world's discovery of the primitive impulse of any discovery and creation are is three-dimensional.
