involves several components:
• Volumetric 3D image, realistic sound.
• 4D platform, repetitive movements occurring on the screen. The viewer feels the slopes, drop, shock, vibration and so on.
• XD effects of the viewer: the smoke, wind, water sprays, the effect of «lightning», bubbles, flash, and also important for full immersion effect «mice» (ie contact with the viewer’s feet).
Now XD market is very well developed in world. In large cities are dozens of similar attractions, but some of them are able to deliver the pleasure of viewing and send you into a real journey through the virtual world.
is a marketing term for an entertainment presentation system combining a 3D film with physical effects that occur in the theatre in synchronization with the film. Because physical effects can be expensive to install, 4D films are most often presented in custom-built theatres at special venues such as theme parks and amusement parks. However, some movie theatres have the ability to present 4D versions of wide-release 3D films. There is no consistent standard for using the term «4D» when describing the presentation of a film. 4D films have also occasionally been marketed as 5D, 6D, 7D, 8D, 9D, 11D, 15D and so on in order to emphasize the variety or uniqueness of their theatre effects. This is scientifically different from actual fourth dimensional space.
is an artificial environment that is created with software and presented to the user in such a way that the user suspends belief and accepts it as a real environment. On a computer, virtual reality is primarily experienced through two of the five senses: sight and sound. The simplest form of virtual reality is a 3-D image that can be explored interactively at a personal computer, usually by manipulating keys or the mouse so that the content of the image moves in some direction or zooms in or out. More sophisticated efforts involve such approaches as wrap-around display screens, actual rooms augmented with wearable computers, and haptics devices that let you feel the display images.
Virtual reality can be divided into:
• The simulation of a real environment for training and education.
• The development of an imagined environment for a game or interactive story.
The Virtual Reality Modelling Language (VRML) allows the creator to specify images and the rules for their display and interaction using textual language statements.
