What is VR projection?

VR projection is a comprehensive integrated technology, involving computer graphics, human-computer interaction technology, sensing technology, artificial intelligence and other fields.

It uses computers to generate realistic three-dimensional senses such as sight, hearing, and smell, so that people as participants can naturally experience and interact with the virtual world through appropriate devices. When the user moves the position, the computer can immediately perform complex calculations to send back an accurate 3D image of the world to create a sense of presence.

VR (Virtual Reality) is virtual reality technology, which is the use of computers to provide users with an interactive, immersive, immersive virtual three-dimensional space.

Hurry, hurry, hurry, bumps, heat, uh, yes.

The difference between virtual reality VR and holographic projection 3D is: ** different, different principles, and different requirements.

First, ** is different.

1. Virtual reality VR: Virtual reality VR needs to be realized with the help of auxiliary equipment.

2. Holographic projection 3D: Holographic projection 3D does not need to use auxiliary equipment, and can be directly **.

Second, the principle is different.

1. Virtual reality VR: The principle of virtual reality VR is to use the grating principle for projection imaging to reproduce the real three-dimensional image of the object.

2. Holographic projection 3D: The principle of holographic projection 3D is to use the principle of interference and diffraction to record and reproduce the real three-dimensional image of the object.

Third, the requirements are different.

1. Virtual reality VR: Virtual reality VR has certain requirements for the best angle and distance.

2. Holographic projection 3D: Holographic projection 3D has no requirements for angle and distance.

To put it bluntly, it is simple.

VR virtual reality is to wear VR glasses, is a kind of technology to deceive the participants' vision, hologram, is just a display technology, the image is displayed, the two of them are completely different technology.

According to the "2016-2021 China Virtual Reality Industry Market Prospect and Investment Planning In-depth Analysis Report" of the Prospective Industry Research Institute, the virtual reality field continues to be hot with the entry of large companies such as Facebook, Gu Qi Leasing Huaige, Sony and Valve, and there have been many billions of dollars in investment, and the VR market is expected to exceed $15.9 billion in 2019.

According to **, by 2020, the VR market, including games, hardware, movies and theme parks, will be about 30 billion US dollars, of which the market size of VR games will account for nearly 50%, followed by VR hardware and VR film and television content. Digi-Capital also said that by 2017, the VR market size will be ahead of the AR market, but with the advancement of technology, the AR market will far exceed the VR market in the future, and AR is expected to reach a market size of $120 billion by 2020.

At present, it is the period of rapid development of VR, there are many employment opportunities, and if you learn well after training, it is still very easy to get employed.
