INSIGHT INTO FULL DOME IMMERSION

Achieving FULL DOME Projections is not Rocket Science but it is
about as technical. Here is a brief insight into the Vocabulary
associated with FULL DOME projections.

art
The principles or methods governing any craft or branch of learning. The quality, production, expression, or realm, according to aesthetic principles, of what is beautiful, appealing, or of more than ordinary significance. The class of objects subject to aesthetic criteria; the craft or trade using these principles or methods skill in conducting any human activity.

artisan
A skilled worker; a craftsperson an artist.

augmented reality (AR)

A field of computer research which deals with the combination of real-world and computer-generated data. At present, most AR research is concerned with the use of live video imagery which is digitally processed and "augmented" by the addition of computer-generated graphics.

Cave Automatic Virtual Environment
(better known by the recursive acronym CAVE) is an immersive virtual reality environment where projectors are directed to three, four, five or six of the walls of a room-sized cube. The name is also a reference to the allegory of the Cave in Plato's Republic where a philosopher contemplates perception, reality and illusion.

entertainment
Something divertingly adventurous that is produced or performed for an audience. Art of keeping people entertained, various ways of amusing people. Amusement, agreeable occupation for the mind, a performance or exhibition of some kind affording pleasure.

fulldome

Fulldome refers to immersive dome-based video projection environments. The dome, horizontal or tilted, is filled with real-time (interactive) or pre-rendered (linear) computer animations, live capture images, or composited environments. Although the current technology emerged in the early-to-mid 1990’s, fulldome environments have evolved from numerous influences, including immersive art and storytelling, with technological roots in domed architecture, planetariums, multi-projector film environments, flight simulation, and virtual reality. Initial approaches to moving fulldome imagery used wide-angle lenses, both 35- and 70-mm filmstock, but the expense and ungainly nature of the film medium prevented much progress; furthermore, film formats such as Omnimax (Imax Dome) did not cover the full two pi steradians of the dome surface, leaving a section of the dome blank (though, due to seating arrangements, that part of the dome was not seen by most viewers). Later approaches to fulldome utilized monochromatic vector graphics systems projected through a fisheye lens. Contemporary configurations employ raster video projectors, either singly or grouped together to cover the dome surface with full-color images and animations.

immerse
To plunge into, to be submerged, to involve deeply, to be absorbed. To occupy oneself totally with something, to become completely occupied, giving all your time, energy, or concentration to it.

immersive
The term immersive refers to the impression that someone has of being somewhere while, in reality, he is physically in another place.

immersion
Extensive exposure to surroundings or conditions native or pertinent to the object of study. Complete involvement, involvement in something that completely occupies all the time, energy, or concentration available. Immersion (virtual reality) is the state where you cease to be aware of your physical self. It is frequently accompanied by intense focus, distorted sense of time and effortless action. The term is widely used to describe video games, but it is not clear if people are using the same word consistently. The term is also cited as a frequently-used buzzword, in which case its meaning is intentionally vague, but carries the connotation of being particularly engrossing.

immersive digital environment

An immersive digital environment is an artificial, interactive, computer-created scene or “world” within which a user can immerse themselves. Immersive Digital Environments could be thought of as synonymous with Virtual Reality, but without the implication that actual “reality” is being simulated. An Immersive Digital Environment (IDE) could be a model of reality, but it could also be a complete fantasy user interface or abstraction, as long as the user of the environment is immersed within it. The definition of immersion is wide and variable, but here it is assumed to mean simply that the user feels like they are part of the simulated “universe.” The success with which an immersive digital environment can actually immerse the user is dependent on many factors such as believable 3D graphics, surround sound, interactive user-input and other factors such as simplicity, functionality and potential for enjoyment. Additional technologies bring realistic environmental effects to the environment—effects such as wind, seat vibration and ambient lighting.

media
Means of communication that reach or influence people widely. The materials and techniques used by an artist to produce a work. Digital media is the creative convergence of digital arts, science, technology and business for human expression, communication, social interaction and education.

research
Diligent, methodical, systematic investigation into a subject in order to discover, establish or revise facts, theories or applications, or to develop a plan of action based on the facts discovered.

science
A particular branch of systematized knowledge. Precise application of facts or principles gained from the study of the physical and natural world and phenomena, especially by using systematic observation and experiment. Proficiency, knowledge gained by systematic study.
