What is the difference between 2D and 3D The difference between 2D and 3D

2D is generally a plane, and 3D is three-dimensional, that is, three-dimensional.

If you want to learn systematically, you can consider signing up for a live online class, and recommend CGWANG's online class. The teacher speaks carefully, you can watch it back after the class, and there are also the same type of recorded classes that you can learn for free (give away lifelong VIP).

Among the training institutions in the field of "3D modeling", [Wang's Education] is the leader in China, and it does not join the branches, but is a chain campus directly operated by the headquarters. Different from many other large institutions of the same type: each campus of Wang's Education is physically face-to-face, the teachers are hand-in-hand, and there are special class teachers from morning to night, and the liver-bursting learning mode will improve quickly, especially suitable for students with poor foundation.

D and 2D have different sensory experiences.

dCompared to it, it is more spatial and immersive.

2D is two-dimensional, and what is on a plane is two-dimensional. Two-dimensional, that is, left and right, up and down, there is no front and back. What is on a piece of paper can be seen as two-dimensional.

That is, there is only an area, not a three-dimensional. Two-dimensional is a kind of flat technology, such as ordinary flat animation, called two-dimensional animation, referred to as two-dimensional.

3D is three-dimensional, and three-dimensional refers to the space system composed of a direction vector in the two-dimensional system of the plane. The so-called three-dimensional, according to popular theory, is just three artificially prescribed interleaved directions (perpendicular is a very characteristic understanding), and with this three-dimensional coordinate, it seems that the position of any point in the whole world can be determined. It turns out that three-dimensional is to determine the position.

3. Differences in games.

2D games and 3D games are relatively easy to distinguish, and the easiest way to distinguish between 3D games is to see if you can convert the 360-degree perspective in the game, and if you can, it is obviously pure 3D.

The differences between 2D and 3D include: sensory, game perspective, vision, data.

1. Sensory: 3D is more spatial and immersive. 2D is flat in representation, and 3D is three-dimensional in representation.

2. Game perspective:

The easiest way to distinguish between 3D games is to see if you can convert the 360-degree perspective in the game.

3. Vision: The reason why people can produce stereoscopic vision is caused by binocular parallax. When a person looks at the same object with the left and right eyes, and the two eyes see different angles, that is, there is a difference between the picture seen by the left eye and the picture seen by the right eye, then two different images will be formed on the retina, and the two images can form stereoscopic vision with depth of field after being processed by the brain.

4. Data: The difference between 3D and 2D is in the data, and 2D only has X, Y and pixel size values.

Applications of 3D:

1. Industrial field. 3D technology can be applied to process control, numerical simulation, CAD CAM (computer-aided design and manufacturing) design, industrial inspection file rounding, remote monitoring, hazardous product production and installation, and remote robot visual display, bringing unprecedented realistic visual effects.

2. Medical and health field. 3D technology can provide doctors and experts with direct test and diagnosis and treatment in remote diagnosis, so that staff can obtain more visual information than a flat display. In addition, 3D technology also has very important application prospects in endoscopic image display, ophthalmic disease diagnosis, MRI, CT, B-ultrasound imaging, surgical simulation and virtual hospital.

1. Definitions:

D: refers to three dimensions, three dimensions, three coordinates, that is, length, width, height. In other words, it is three-dimensional, and 3D is the concept of space, that is, space composed of three axes: x, y, and z, as opposed to a plane (2D) with only length and width.

D: Also known as a flat graphic, the content of a 2D graphic is only horizontally x-axis and perpendicular y-axis.

2. Performance: D:

Computer, Internet digitization of 3D three-dimensional technology, 3D movie three-dimensional effect.

d: Graphic animation, handmade comics, illustrations, etc.

2D and 3D are two common concepts in digital graphics, and they represent different dimensions. 2D stands for 2D and 3D stands for 3D, and there is a clear difference between them.

2D graphics can be represented in either vector or bitmaps, where vector maps use geometry instead of pixel lattices to create shapes, so that the shapes are not distorted no matter how they are scaled.

Instead, a 3D figure is made up of many 2D layers, each representing a cross-section of the 3D object. It exists in three-dimensional space and has three dimensions of length, width, and height. 3D graphics can represent objects and scenes with depth and realism, such as buildings, cars, people, etc.

3D graphics are typically represented using a polygonal mesh, where each face is made up of a number of triangles or quadrilaterals, each of which is a flat graphic shape that together make up a 3D object.

Specifically, 2D graphics typically include text, images, graphs, and charts, while 3D graphics typically include animations, games, virtual reality, and architectural models. 2D graphics are usually static, while 3D graphics are usually dynamic. In addition, 3D graphics require higher computing power to render, often requiring higher levels of software tools and hardware devices.

In conclusion, 2D and 3D represent two common concepts in digital graphics, and the main difference between them is dimensionality, 2D only has length and width, and 3D has three dimensions: length, width, and height. 2D graphics are presented on a flat surface and can be used for text, **, etc.; 3D graphics are presented in three-dimensional space and can be used for animation, games, etc. <>
