For a reason: the flicker of badly synced glasses or fluorescent light messing up the effect. without specific issues, 3D hasn't caused anybody headaches, or do you see a lot of people walking around outside holding their heads? - Oh never mind, I guess that must be the reason for all the OTC headache pills that have been selling well since the invention of Aspirin sometime in the 1800's... that damned third dimension we always have to deal with.  Actually, the issue comes from convergence vs. focus. Stereoscopic 3D images aren't actually 3D - it's a 2D image that flickers rapidly between what your left and right eye would see, and the glasses are synced to the image to make sure that each eye only sees the correct image. Now, when you have a particularly deep stereoscopic image your eyes will adjust their focus to try and focus on the deeper objects. But because the object isn't actually there, it's on a 2D screen that's a fixed distance away, you're asking your eyes to converge on one point, and focus on another. And that's not the way eyes work in real 3D (also known as Stereopsis or depth perception) so you can't compare the two. xaja wrote:KFenn wrote:And if you suffer from Myopia or Hyperopia then you can't perceive the 3D effect very well, which covers a fairly large portion of the population. What?  A fairly large portion of the human population or just your family? .....like what percentage do you regard as "fairly large"? I guess all those Japanese, Taiwanese and Koreans should just stop working on making better 3D, cause there's a bunch of handicapped people who don't get anything out of it. You go get people to stop building stairwells too, those aren't fair either.... You have no ******* clue what either condition is, do you? Myopia and Hyperopia are short and long-sightedness, respectively, and they affect a good portion (not a majority) of the population. Don't just flame when you don't even understand what you're talking about.
Given I am Short Sighted.. in vision and I can wear 3D glasses with out a problem and get the 3D effect I don't see the problem.. the biggest 'issue' with 3D glasses is the fact that you either have to wear them OVER your existing Glasses which can cause issues with the Lens or you have to be wearing Contacts.. which can cause for some people their own issues...
Plus most TV's are using the 'flicker' option, one lens opens the other closes.. at really fast rates of speed, This can and WILL cause headaches and set off Epileptic Fits faster then a psychodellic disco ball.. especially for those who are epileptic and those who's eyes can actually follow high refresh rates (Those who typically get a headache from CRT's with a Refresh lower then 75hrtz.
On the other hand, Polarised Lighting, which is how many of the threaters do 3D is completely diffrent, there is no flickering it's simply two images and a polorised light filter over your eye.. one clockwise the other anti.. and you get to see what is projected at that polarised wave length.
As much as people want to say 3D is a 'gimmick' sorry guys but given the amount of 3D camera's and everything else now entering the industry.. 3D is here to stay.. though how they can call it 3D is beyond me, it's not 3D.. it's 2.5D or 2D with Depth Perspective, 3D would be a f'n projected Hologram. |
