Key Technologies Of Virtual Reality
- Aug 25, 2018 -

Virtual reality is a synthesis of many technologies, including real-time three-dimensional computer graphics technology, wide-angle (wide-field) stereoscopic display technology, the observer's head, eyes and hands tracking technology, as well as touch/force feedback, stereo, network transmission, voice input and output technology. These techniques are explained below.


Real time 3D computer graphics


In contrast, it is not too difficult to use computer models to produce graphics and images. If we have enough accurate models and enough time, we can generate accurate images of various objects under different lighting conditions, but the key here is real-time. For example, in flight simulation system, image refresh is very important, and the image quality is also very high, coupled with very complex virtual environment, the problem becomes very difficult.
