3D or not 3D

March 13, 2011

Sorry folks, I’ve not posted in a quite a time.   It’s been hectic, plus I’ve been experiementing with a lot of resources that haven’t fully proven themselves.

I have spent some time recently looking into 3D and 3D resources.   Before I go any further though I need to clarify something.  3D is a gimmick.   It causes too many eye-fatigue problems for too many people to be used for anything other than “wow factor” events and theme parks.  Estimates for people who have problems with 3D video range from 12% to 30% of the population!  That’s people who get headaches, people who can’t see 3D and people who can’t see specific types of 3D. 

Personally, I can only see what I call gross 3D, that is the real in-your-face stuff, the stuff that shoots our of the screen.  My eye condition means all the subtle stuff involving depth behind the screen totally passes me by.  So you see, along with 30% of your class, I have a vested interested in making sure 3D is used right.

Over the next view posts I’m going to break down 3D into it’s different elements (I could have used “dimensions” I suppose) and the first one is that calling it 3D leads to confusion.  How?  Because computers which create environments in which objects exists are already making things in 3D.  Jurassic Park, Toy Story along with every movie since used computers to create a 3D world, but they showed it only in 2D.  

What you put glasses on, you’re actually looking at Stereoscopic 3D or s3D.   That’s where two different views appear on the same screen and the glasses ensure you only see one view per eye.

Next up, I’ll explain the differences between and benefits of Passive Linear, Passive Circular, Active Shutter, Dolby Digital and Imax s3D display systems.
