Today’s post is brought to you by Anna from Online Degree; she contacted me a week or so ago with some topic ideas, I loved this one so much that I asked her to go ahead and take it wherever she wanted. Over to Anna!
The Ongoing Evolution of 3D Entertainment
When it comes to 3D entertainment, you could certainly say we’ve come a long way, baby. The
first big wave of 3D films arrived in theatres back in the 1950s accompanied by flimsy paper
glasses with blue and red plastic lenses. It was a gimmick that actually caught on, unlike other
hare-brained ideas like the ill-advised Smell-o-Vision. Today, ideas are already in development
that would allow people to access 3D entertainment with no glasses whatsoever!
Blue & Red Paper Glasses
The original 3D experience with the paper glasses was achieved by filming using two slightly
separated cameras, one camera using a red filter and the other using a blue filter. When layered
on top of one another, the two shots created an anaglyph image, capable of tricking the brain into
seeing a 2D film in 3D. The 3D effect from such images could only be seen when a filmgoer
wore the red-blue paper glasses. The idea is to recreate how you see in real life. One of your eyes
sees one angle and your other eye sees another angle and when their powers combine (try not to
think of Captain Planet), you have everyday human depth perception. The red-blue glasses are
designed to allow the blue shot to enter one eye and the red shot to enter the other eye while the
brain takes it upon itself to see what’s in front of it in 3D, according to American Paper Optics.
Next came the slightly cooler polarized 3D glasses that looked a lot less like a cereal box toy and
a lot more like Wayfarers. The polarized glasses work by limiting the type of light that enter the
viewers’ eyes. The movie is filmed using two synchronized projectors that place two different
images on a movie screen with two different polarizations. Like the red-blue paper glasses, the
polarized glasses only allow one of your eyes to see one view and the other to see the other view.
This produced a much better image than was seen using the paper glasses.
Avatar and 3D TVs Bring 3D Back to the Spotlight
From its humble beginnings, 3D entertainment has advanced to a whole new level along with
modern technology. The next notable step forward was the advent of IMAX in the 1970s, and its
expansion into entertainment in the late 1990s. More recently, 3D entertainment has made a big
splash again with the wildly popular Avatar experience where James Cameron used stereoscopic
filmmaking, reviving interest in all things 3D.
This January marked the onset of sophisticated flat screen 3D televisions. Naysayers have said
that 3D televisions aren’t practical enough to catch on. After all, if you’re hosting a Super Bowl
party, are you also going to shell out the cash to buy expensive 3D glasses for all of your guests?
Keep in mind that some of the best 3D glasses easily cost more than $100. Forget the Super
Bowl party, even. What about having to buy enough glasses for all of your family to enjoy their
favorite sitcoms? The average family won’t be able to afford all the glasses it would take to make
the idea of the 3D television really pick up speed.
The Future: Glasses-Free 3D
But what if we could have a 3D experience without using glasses? The development,
improvement and expansion of this type of technology could really get 3D TVs flying off the
shelves. Toshiba is expected to start selling a glasses-free 3D TV this month in Japan. Toshiba
uses “auto-stereoscopy 3D technology,” according to the Christian Science Monitor. An article in
PC World discussed how glasses-free 3D TVs are cost-prohibitive, have too small of screens and
will also require you to sit in a certain spot to watch in optimal 3D, but none of this is the point.
The point is that the technology is available and improving. Now even tech giant Apple, Inc. has
secured a patent for a glasses-free 3D display system. The possibilities are endless. Now, if only
more people would focus on getting the ball rolling for holographic TVs.
