Words represent concepts and ideas they are the medium of human communication (If we all speak the same language, snap je?), and the meaning of words change as the difference of perceptions do. But do words have any concrete representation? Do they still contain their original message , and how do those contents change.? For instance the words "up" and "down" have no meaning .they were invented to explain what seemed to be happening in a world that was believed to be flat. But we now know that the earth is spherical and none of the perpendiculars are parralel ( as they would be in a flat world). What may be up at one point maybe down at another. This metamorphosis is applicable to many aspects of our society and I have been questioning these for awhile . Is "Democracy" still used with relation to its original meaning ? Is there still an understanding of the word "freedom"? In my piece I plan to question these notions of propaganda, and its other aspect will revolve around the use and abuse of words within consumer culture. The consumer culture bombards citzens with catchy words and phrases that would insult your intelligence. "Need", "beauty" , "hapiness", and " all you can eat" are a smidgen of words that have been altered in meaning. Of course this is all based on my own perception of the world but this is what I want to represent anyway.
In my piece I will be utilizing holograms and I think it is important to understand how holograms work. In essence a hologram ,the actual medium that contains all the information, is a very high contrast black and white film. The record on the film is of the intensity differences on the object which form a pattern that one may ultimately recognize as the object. The functioning of the hologram relies on the use of lasers (Light Amplification by Stimulated Emission of Radiation), but more importantly the angle difference between two waves.

holograms & Holographic video.
However the production of holograms and more importantly holographic video , can be simplified with the help of computers.The method which I will describe makes use of scanline based computer techniques. The widely available OpenGL application takes the advantage of acceleration by computergraphics hardware subsystems. This is an efficient way to produce full parallax displays.The OpenGL library provides a uniform rendering interface to the full spectrum of graphics systems from videogames to the most powerful graphics work stations . OpenGL is tuned to maximize rendering speed based on a particular computer's architecture and any install graphics acceleration devices. When necessary, higher quality images can be rendered in OpenGL by combining several different rendered images.With the help of a program like OpenGL , holographic images can be rendered at high speeds.
I have described how rendering of this project is feasable , but now I'll get into the display/projection aspect .
The MIT Media Laboratory-spatial imaging group. is currently working on an imaging system that can render and display computer generated holograms at near-video rates . I think that the Mark- I holographic video display would be most suitable for my project's needs.
DIAGRAM OF THE MARK-I.
I have reviewed different possibilities for
what to use as the best tool for my holographic piece. Companies
Dutch holographic have devices that were feasible to use , but they offered nothing with regard to holographis video. Along the same lines was the information that I gathered from HOLOPHILE.INC who develops 3-D displays for corporations with really interesting , short movie possibilities. However no information on the functioning of their system was offered.Thus I'll stick to the Mark-I display.
The Set-Up &
The location for the piece could be within any dimly lit place, prefferably indoors. As long as the projector itself would located out of sight . or to be seen as little as possible. This considering the fact that the holographic video is the piece in itself., and I suppose that with the fact that it changes from different viewpoints it would need a spce for the observer to be able to move around the projection.
The idea of using holography for the theme of words as illusion is of course the fact that holograms are illusions , To enhance that point in a way. I have mocked up a basic representation of the preliminary piece in director to give a slight idea of how it might work.
As is quite obvious this is still a proposal so the final project is still open for suggestions and comments. And I would appreciate all the feedback for this proposal.
