Virtual Reality VR the computer-generated simulation of a three-dimensional image or environment that can be interacted with in a seemingly real or physical way by a person using special electronic equipment, such as a helmet with a screen inside or gloves fitted with sensors.
Perhaps the most striking transformation effected by these (digital) technologies is the change in our perceptions of materiality, space, and information, which is bound directly or indirectly to affect how we understand architecture, habitation, and the built environment. – Elizabeth Grosz
In architecture, the digitally generated walkthrough and fly-by of a virtual building design have become so established that they are now commonplace. Indeed, there is even evidence of a hardening resistance to their apparent ease and slickness. Furthermore, the ability to recreate a realistic simulation using the computer has caused a reaction in some quarters accompanied by the call for a return to freehand drawing.
