Humans (and most predators) have two eyes in the front of their head. This “binocular vision” improves depth perception, letting a hunter estimate the distance to its prey.
In addition to stereoscopic vision, depth perception also comes from a number of monocular depth cues (depth perception cues that can come from only one eye, or more precisely, that come from the 2D version of the picture that you see). These cues are important to good 3D video, as your brain will expect your stereoscopic perception to closely match your 2D perception of the scene you are viewing.
Monocular cues include:
Your memory of the shape and size of different objects: combined with the relative size of the image you see, this lets you perceive the distance to that object. For example, in the photo below, if you are familiar with the size of the bricks that the squirrel is standing on, you can quickly perceive the size of the squirrel, and your distance to the squirrel.
Perspective: Objects at greater distances appear smaller than near objects. Parallel lines appear to converge as distance increases. This effect is obvious as you stand on a straight road or path and look down the road, or when you look up at a tall building.
Occlusion (interposition): If we see two objects, where the first object is blocking part of a second object, we recognize that the first object is closer. In the photo below, you can tell that the tree in the center is closer than the building because it is blocking your ability to see part of the building. Occlusion helps us estimate the relative distance of objects in the photo.
Shadows and Highlights: Help us to see objects that are raised above or recessed into a surface. In the photo above, we can see that there are bumps on the tree trunk, thanks to the shadows and highlights.
Unfortunately I am one of those who recently purchased a new TV. It will be quite some time before I upgrade.
I understand the author's preference for shutter glasses (especially since it's a certain product's preferred method of choice) even if I don't share it, the major limitation is having to buy a pair for all your friends coming over, which gets impractical until they are more commonplace.
Also polarized solutions are not limited in resolution if they are set-up beyond just the example provided in this article (like they do in the theatre with dual projectors ) and may have an improving single source future with 2K and 4K displays on the horizon. It's a question of preference, but it seems like the full story wasn't explored on that subject.
Now on to a pet peeve: I love the part about "While set-top Blu-ray players will need to be replaced, PC-based Blu-ray player software can be upgraded." as a subtle product benefit plug.
Unless it's a free upgrade, you are still replacing the software, not upgrading it (it's not a plug-in), and you're likely forking out nearly the same amount of money for the 1/100th of the cost to produce that software update, so it's not like it's a major advantage. Especially when upgrading requires a FULL upgrade to the most expensive model Power DVD (version #) Ultra 3D, and I can't simply add it to my existing PowerDVD bundles thus potentially changing my backwards compatibility (Ultra 9 already removed my HD-DVD support from Ultra 7 that I upgraded on my LG HD-DVD/BR burner
, until then it's $99 (or $94.95 for loyal saps) vs $150-200, plus with the set-top route now I have a second BR-/DVD player for another room or to give to a friend (the BR software on its own is useless to give to someone else without a drive), and that's not even compared to the free PS3 upgrade.
Also can someone explain this statement;
"Blu-ray 3D video decoding solutions can be expected for ATI Radeon 5000-series graphics in the future."
Didn't Cyberlink already show their BR-3D solution on ATi hardware last year? So what's the issue?
Also why is it limited to "GeForce 300M-series mobile graphics" when often the core is the same a previous generation 200M series (example GTS 350M / 250M )?
And this section "Full-quality 120 Hz frame-sequential 3D video (such as Blu-ray 3D) is only supported through a High Speed
HDMI cable to a HDMI 1.4-compliant TV. " seems to miss the DVI dual-link to monitor option currently being used for 3D on PCs, and also the dual 1.3 input monitors/TVs.
A nice little article for people unfamiliar with 3D, but there's a subtle under-current of product preference/placement in it, and far too many generalities with little supporting information. :??:
also some info on AVRs and how a 1.3 hdmi AVR might pass on 3d video and still decode bitstream audio, or not - do we need 1.4 hdmi AVRs to decode audio from a 1.4 source? we shouldn't need 1.4 receivers since the audio standards haven't change, but I'm understanding that in fact we do neeed new receivers. :/
This piece is a prelude to tomorrow's coverage, by Don, of Blu-ray 3D on a notebook and a desktop. Perhaps that one will answer any of the questions you were left with here?
As for AMD, Tom and I went back and forth on this piece, and we agreed that it was critical to get AMD's feedback on Blu-ray 3D readiness. The fact of the matter is that it isn't ready to discuss the technology. It's behind.
The mention of dual-link DVI was in the first revision of this piece and removed in a subsequent iteration. I've asked the author for additional clarification there and should have an answer shortly.
It turns out the demo (I think it was at CES?) only used CPU decoding over an ATI graphics card; the Radeon did no software decoding.
The Cyberlink rep tells me that Blu-ray 3D software decoding is extremely CPU-dependant and might even require a quad-core CPU. He said all four threads were being stressed under software decoding, not sure what quad-core CPU they were using though.
Definitely something I'd like to test out in the future...
These implementations, while ever more impressive, are still being threshed out. Because of possible physiological side effects, I think I will NOT be a first adopter, with this (particular) tech (3D).
Anyone ever watch that movie "THE JERK", with STEVE MARTIN ??
= Opti-Grab =
... I can see all these class-action suits by parents of cross-eyed gamers ... hope not, tho ... I *AM* very much looking forward to the fully refined "end game", for 3D ...
Additionally, the very best desktop workstations are only just now catching up to standard (uncompressed) HD resolution ingest and edit/render ... since that bandwidth IS shared, between both eyes, this may be a non-issue.
I will let the kiddies and 1st adopters take-on all those risks and costs.
Please let me know when it is all "fully baked" and field tested!
