What is a 3D Stereoscopic Image?
When humans perceive the environment around them,
each eye sees a different perspective image. These two images
give rise to the perception of true depth. Most printed images
which look 3D are classified as monoscopic images. Monoscopic
images try to simulate depth by using shadows and rendering
techniques.
A stereoscopic image, on the other hand, appears
to have real depth where objects can even seem to leave the
surface of the display device and hover in the middle of the
room. A stereoscopic image is composed of a right perspective
frame and a left perspective frame - one for each eye. When the
right frame is viewed by your right eye and the left frame is
viewed by your left eye, your brain will perceive a true 3D view.
What is Stereoscopy?????????
The difference between simulated 3D and
stereoscopic 3D is that in stereoscopic 3D a distinctly different
image is being shown to each eye simultaneously. The images
represent two different renderings of an idenical environment
htat have been captured from positions that correspond to the
location of the left and right eye.
How Stereo Vision is accomplished...??
This is accomplished by creating two different
images of the world, one for each eye. The images are computed
with the viewpoints offset by the equivalent distance between the
eyes.
There are a large number of technologies for
presenting these two images. The images can be placed
side-by-side and the viewer asked (or assisted) to cross their
eyes. The images can be projected through differently polarized
filters, with corresponding filters placed in front of the eyes.
Anaglyph images use red/blue glasses to provide a crude (no
color) stereovision.
In the section VI of
Virtuality&Interactivity II, the visitor will be able to
enjoy a real and stereoscopic vision of the city of New York,
Guatemala!! Wearing the the stereoscopic lenses, the visitors can
have a real-stereo experience as as if you were actually there,
close, within the Big Apple, the terrific experience of the
wonders of the Grand Canyon not withstandidng you are comfortably
sitting in the exhibit space of Virtuality &I Interactivity
exhibit.
Moreover you will feel the actual emotions of
travelling on a ballon, the impressive beauty of the nature of
the grand canyon as if you were actually there, travelling on an
icarius with stereoscopic lenses.
Ray Hanissan, the author of these stereoscopic videos will come in person to stage his own works and dialogue with the public about virtuality and interactivity and share his experience in the area of production.
