Is 3D at home a good idea?

Came across an interesting article this afternoon that I thought I'd share....

I've seen home setups on the net and just accepted that it seemed like the next logical progression beyond HD. But now the more I think about it until the 3D technology improves that it doesn't cause such an eyestrain there's no way it could ever takeover the entire market such that everything goes 3D, in the way that slowly all channels are starting to broadcast in HD.

 

Seriously, who want's to put on glasses to watch TV at home, seems a bit annoying. Perhaps it would work best if it worked like SAP where you get a secondary programing option that you could switch too.

The CEO of Sony has predicted that within 5yrs you will not need glasses for the 3D. And they already have the technology for 2 people to watch independent channels on the same television using active glasses

Also most tvs are also used as accessories to playstaion X-Box etc. Just because a tv is 3D enabled it doesnt mean you have to use it in that mode. It's merely another option.

A lot of 3-D games are already 3D and Warcraft teamed up with NVidia at blizzcon to demonstrate it in 3D. Somehow I don't think this "fad" is going to go away.

Hi Bob

Is it a passive or active system you are rendering for. What software are you using. I ask because I am currently using Spatial View with max rendering for active glasses and would be good to have someone to bounce ideas off.

Having to learn by trial and error at the moment as to what enhances and what depreciates the immersive experience at the moment

I am not at all convinced that we'll be seeing a mass uptake of 3D. DVD, HD, digital have all been a success because in essence, people have not been asked to change their viewing habits, (other than upgrading equipment).

 

Now they're expecting everyone to sit around the TV wearing cumbersome glasses, which feels more like a flaw than an advancement. I just see this as a minority fad; that is until the images can be projected in 3D without the viewer having to do anything different.

As I already said the glasses are not intrinsic too many systems and developments are continuosly ongoing in this area.

 

I don't think it will replace anything it will merely enhance current capabilities and has too many potential applications (games being a big driving force) to be simply discounted as a fad. But time will tell

I all honesty I am not sure what system the guys are using but I assume active. I have just been told to render 24fps for the left and right eye (70 mm apart) at 1998*1080. I am about to send the test off on Monday and will let you guys know how it goes. Will try to siphon some more information out of the cinema guys as to how they process the frames after I have delivered them.

 

I think this technology would be awesome for gaming with or without glasses.

Want to start a new thread with ths job Bob? btw, I did something similar ages ago. I seem to remember it was better to just slightly exaggerate the eye distance, to around 12cm. We were working with Hull University. They were very free with their research, it may be worth contacting them.

I was just about to start a new thread asking how can we use these new 3D TV's for Arch Viz but I thought it would fit into this discussion. I looked into 3D TV's about 3 years ago when they were around 25K and you could view the 3D content without glasses. I'm pretty sure the 3D glasses are only the first step and if 3D really takes off they will disappear pretty quickly as better models are made. My my real interest is in how we can use these TV's and projectors right now in arch viz presentations. It sounds like some are already producing content for this purpose so other than having to render out two different images one for the left and right eyes what other issues do you need to consider? Once you get your work rendered out what would be the best way to get it onto the TV? I've heard that 3D Blue Ray players are coming but how long before there is software available to export to that format?

$25K? Yowza. Seems like alot to pay just to not have to wear the red and green glasses. I've experimented with the red/green method of rendering "stereoscopic" images and found it to be a fairly straightforward process. You don't need any kind of special display to view it though, just the 50c red and blue glasses. It ought to work on any TV...

Yea I've worked with the red and blue glasses before but I've found that it's really hard to maintain your colors with any degree of accuracy.

 

I'm not sure what you mean.

 

The process I followed required you render 2 images, 1 for the left eye, 1 for the right slightly offset from one another. I too found that a slightly exagerated distance (as compared to exactly how far appart your average eyes are spaced) works best. You then bring the images into PS or AE. For the right eye image you create a new layer and use the paint bucket to make it R255,B0,G0 and change the blending mode to screen. For the right eye you do the same but use R0,B255,G255 for your fill color.

 

I forget which eye is red and which eye is blue green to be honest but you can tell by looking at whatever glasses you're using.

 

Flatten both images. And copy and paste one on top of the other as a new layer and set your blending mode to multiply.

 

Now you've got you stereoscopic image with the correct colors :-) Like so...

To me it's very distracting to have to look through the tinted glasses, you do see the colors of the object your looking at but your also seeing the blue and red from the glasses at the same time. For architectural presentations I just think it's to distracting for most people which is why the polarized glasses are so attractive because you don't have that distraction. The new 3D TV's also woulden't have that problem but I have a feeling making content for them is more involved than the red/blue old way.

I had heard something like it would be built into the TV for it so switch back and forth between right and left eye within a fraction of a second. I'll have to do some digging to see if that's the case or not. The images I've been seeing from CES seem to indicate that the majority of this new 3D TV technology is basically the old style method.

 

Even if it were cone within the TV (switching back and forth between eyes) then it would seem lack that could be done within the content itself rather than needing some sort of special display. No?

I saw something recently saying that Samsung (I think that was the company) had a 3D display that does not need glasses at CES this year. Even if that's correct, it's still concept/prototype, I would imagine.

 

Going back many years I used infra-red controlled LCD shutter glasses that came with an nvidia graphics card. It required a monitor refresh at 120hz. It worked with any Direct3D program via a special video driver. I used it to play Tony Hawk skateboarding games. After twenty minutes I would be about to throw up. Otherwise, the 3D worked perfectly.

No probs Tommy. I will start something up as soon as I have worked through the process.

So how would that work, I wonder? Surely your two eyes need to see different images for it to work - a screen that flicked quickly between two images would still be picked up both eyes? Or are we talking implants here...? (No, not that sort! ;) )
