Virtual reality (or VR) consists in the use of technology and computers to generate a complete environment that allows immersion and interaction in real time by its users. VR is dominated by the use of computer graphics to render this environment.
The traditional five senses (sight, hearing, touch, smell and taste) enable us to interact and relate to the surrounding environment. Through them we can perceive everything around us.
Immersive environments are systems to visualize and interact with VR, composed subsystems such as screens, audio and input devices.
There is a number of virtual reality frameworks available. See also graphic engines.
The use of high performance, low cost environments is one of the problems that VR still faces, since many applications demand high performance, and multidisplay environments need several video outputs. It is common to use graphic clusters to run them, which required distributed programming
