3DF33D.TV

You have your 3D camera and you want to share your awesome pics and videos. What do you do?

I went looking for sites that specialise in enabling the sharing of 3D content and found a few. Each has strengths and weaknesses and none of them are perfect. But the price (free) is certainly not heavy and you can't really complain too much.

My aim in sharing 3D content was to make it as easy as possible for others who may not have much experience with 3D images and how to use them. I also wanted a site that let the user turn the 3D off if they just aren't up for it.  I also like to view my images in red/cyan anaglyph full screen on my big PC monitor. The effect is amazing, but sometimes the parallax in the anaglyph images is 'off' and most sites offer no way to fix that.

3DF33d.TV does all these things. This is why it's my favourite 3D viewing and sharing site by a reasonably wide margin. It's the only site out there that lets you fix misaligned parallax and see a good-quality, high resolution image (or video) at the same time. No one else comes close. The site provider / operator, Keith Fredericks, has put together something very special for us all.



Up front, 3DF33D.TV requires your web browser to support WebGL. That means you need a very recent version of Forefox or Chrome. You should see prominent graphic explaining your WebGL options and how to enable it of you don't have it.

Once the WebGL is sorted (if you had to do anything at all), the default viewing mode is 2D. You have to select a 3D viewing mode in order to see it and the selection button is top and centre on the main page.


When you click on the "Select 3D mode" icon you're taken to a page that offers a wide range of choice for 3D viewing options. To be honest, I don't know what half of them are (yet), but I'm sure the people who need them will identify them readily. 


The main selection list above should be good enough, but if you need something more specialised, you can click on "Other Modes" and gain access to an additional list of 3D viewing modes. For example, regular (full colour) red/cyan anaglyph may be good enough for most things, but if you have an image that has a lot of  red and / or blue in it, your glasses will make those parts of the image look......just wrong. So, instead, you'd click on Other Modes and select "Dubois", which alters the shading of the reds and blues in the images to optimise them for viewing through red/cyan lenses. A bright blue sky on a sunny day will look much more natural using Dubois red/cyan anaglyph  than the regular full-colour flavour. It's this kind of flexibility that makes 3DF33D.TV a win for me. This works for both stills and video. 


Fixing the parallax in red/cyan anaglyph mode (if you selected one) is easy for any still or video. Moving the mouse cursor to the top-right in the image or video when, not in fullscreen mode,  gives you access to the parallax adjustment tool (I don't know what Keith calls it.) With your glasses on, just use the mouse pointer to slide the white dot up or down until the ghosting disappears. Then you can make it fullscreen. The parallax adjuster is also available in fullscreen mode, but doesn't work. It will immediately go to the highest negative number and stay there, so best to do this before going to fullscreen.  

Images can be up to 20MB each. Maximum resolution is 3048 x 1080. The site supports "png gif jpg jpeg mpo" image formats. It can also handle *.jps files if the file being uploaded has been renamed to end in *.jpg. Always make a copy. Don't mess with your originals. I have an LG Optimus 3D phone camera and it produces *.jps files and this method works fine for me. 

This is all goodness. Could 3DF33D.TV be better? Sure. I admit, I don't know what Keith's goals are for the site, so what might be good from my point of view might not with his vision of where he wants to take 3DF33D.TV. Keith posts a blog entry on the site every few days and they are always informative and or entertaining. His enthusiasm for 3D shines through brightly. He recently published a book: "The Future of 3D Media". I bought an e-copy copy via Amazon for US$9.99. 

The site allows you to use tags, but has no folders. So if you want to organise your uploaded content you will need to think about a set of  tags that will let you group your images in ways useful to you. I use permutations on the date that include my user-id initials as other people may also want to use dates and won't want my images mixed in with theirs. For example, we can't ALL use "201107" for July 2011 without overlapping.  I also add a word or two about the main subject, the location - city and country, my username (so I or others can select only my images/videos) and the device that shot the image ("LG Optimus 3D" or whatever). There is a search function, but any new user will rely heavily on the "new, hot, random" selection choices on the feature pages to locate content of interest. There is no high-level topic index.  You have to browse and when you find a user whose content you like, you can drill into it.  

It's possible to rate images and videos as one to five stars. I usually do. But no one else using the site seems to use this much. You can also leave comments, but I'm one of the few who do. There is no real "community" side to the site. If you want forums for sharing, learning or teaching, you'll have to go to another site. The fonts on the menus can look a bit "chunky". In some browsers the words on the menus are black on black unless you're mousing over them. But generally the site is stable and stuff just works. I've found in video playback that the player doesn't really buffer much of the stream, so if the network path between you and 3DF33D.TV is being "choppy" due to congestion at some point, there is no way to get around it. For this reason, I can only very rarely use the 720p HD playing mode with the site, but the 360p mode works very well almost all the time. 

The user community on the site is still quite small as far as I can tell, but the hit-counts on the content seem to be rising, so interest appears to be growing. The more content there is, the more people will want to go there. 

The summary for me is that 3DF33D.TV is the best 3D sharing site out there. If you haven't tried it then it's time you did.

LG Optimus 3D: I love the 3D!


My LG Optimus 3D arrived 3 weeks ago. I'd ordered it from mobicity.co.nz on a Thursday afternoon. It left Guangchou on Friday, the next day. It was in my hand by Noon the following Monday.

I'm impressed. But it got better.

It's a Telecom XT version (P925G) and is rich in Rogers livery, intended for sale in Canada.

I'm really impressed with the Optimus 3D. It feels good. Runs really quick and smooth. The 3D screen is actually pretty good. I'm able to watch 3D video from YouTube 'natively' on the (4.5"? - bigger than the HTC Sensation) screen without crossing my eyes or wearing glasses. That's nice!

OS

The LG Optimus 3D is pre-loaded with Android v2.2 upgradeable to 2.3 in October '11 (I'm told).

Screen

The screen resolution is 800x480...which on a big screen works out really well for these 53yo eyes.  You can actually see the detail in the icons! I'm not used to that as my other phones have had smaller screens or higher resolution. Either way, things were smaller on the screen.

Performance / Capacity

The phone's dual-core 1GHz processor delivers good, snappy performance. The 512MB of RAM may be less than other top-end phones in relative terms, but it doesn't appear to matter in absolute terms. Perhaps this is due to the "tri-dual" implementation LG have used: dual-core, dual-channel, dual RAM. Whatever, this phone can't be accused of being slow.

There is 1GB of app storage. not as much as some other high-end phones, but more than I have ever used. I still have 400MB left after installing every app i can think of that I might want to use every now and again...maybe. Games typically put their data on the sdcard, so that doesn't matter, either.

Without adding external storage, you get about 5.5GB of internal storage space - of which about 1.5 GB is used to store included 3D apps. I added a 16GB Class 10 microSD. I suspect they have an 8GB sdcard hard-wired inside and have subdivided it into partitions for system, installed app storage and user data / app space.

Camera and Photos / Video

The 3D photos the phone produces are 5mp 2D stills or 3.2mp x 2 stereo images. Just good enough for me, but may not be for others. The camera app has a built-in editor for editing 2D and 3D photos. It's actually very useful. You can tweek the pics righrt there on phone before sharing them. You can crop or resize. You can manipulate brightness, contrast, hue, saturation, RGB and there is an "auto" option as well. You can then save the file with a new name if you prefer - and I always prefer as I never alter my originals. You very often can't just take them again. The moment passed.

The files are in *.jps format, which is basically side-by-side, cross-eyed, jpeg. If your favourite PC or phone-based viewing / editing app can't see *.jps, you can just make a copy (I never mess with the originals!) ending in *.jpg and it should be able to see them. The still camera's default still image aspect is 4:3. I prefer 16:9....but I have my Fujifilm 3D camera for that.

Every 3D sharing web site I know of can handle *.jps directly, except 3df33d.tv. 3dfeed.tv will allow you to upload the LG Optimus 3D's pics provided the file name ends with the *.jpg extension. No problem. Just make a copy that ends in *.jpg.

The video the LG Optimus 3D produces is 720p HD. The quality is pretty good for a phone and considering there are two images in there....not just one.

Parallax

The LG Optimus 3D's twin cameras are 25mm apart. That's about 1 inch, for those in the last country on Earth that isn't metric. (You know who you are). That is about 1/3 the distance between human eyes, which is about 75mm (also like the Fujifilm Finepix Real 3D W3 camera). This means the 'parallax' - the difference between the two views - is also much less. What THAT means is that you lose the sense of depth sooner than you would if the same scene were viewed through human eyes The upside - and there is one - is that you can see depth clearly in photos taken at much closer distances than with a camera that matches the human eye distance. For example, the LG Optimus 3D phone can happily snap away at things only half a metre (1/5 feet) away to good 3D effect, while the Fujifilm FinePix Real 3D W3 camera struggles to properly represent things in scenes that are close then 1.5 metres (about 5 feet) away.  This matter particularly if you want to use the red/cyan anaglyph 3D viewing method. Images that are too close just won't line up right if the parallax is too great. The LG Optimus 3D is great for 3D of people and things close to you. A camera with greater parallax (like the Fuji) is better for  outdoor scenes and landscapes...and people and things more than 3 metres (10ft) away.

The UI

The Optimus 3D's UI looks like Samsung's TouchWiz, but is actually usable....I kinda like it. We'll see how we go. I removed all the Rogers apps from the Home screen. No big deal. They don't work anyway in NZ.

The "3D Space" UI is also good fun. A sort of spin-able horizontal wheel of 3D aspects (3D Apps & Games, YouTube, 3D Gallery, 3D Apps, 3D Camera) all presented in a 3D display with depth that I really like. A new owner of the phone can see immediately a strong hint of  the potential of this device. Opinions will vary. They always do with 3D. :-)

I really like the glass on the LG Optimus 3D. I use SlideIt, a swipe keyboard...and the glass on the LG doesn't get "sticky" if you're writing a long email. On my SG-S and HTC Sensation I noticed the glass face can gradually increase friction with my finger tip. This doesn't happen with the LG. Odd....but good.

3D Games

I've also had a chance to download the 318MB for "Asphalt 6" racing game - included with the phone (Remember - included stuff may vary from telco to telco). I think it looks great in 3D. :-)  I've also had a quick peek at "Nova", also included, and it looks like it could be fun. The graphics are good enough for me. There is a golf game, too. Haven't tried it yet. Also noticed I can play any 3D video on YouTube in 3D on the screen without needing glasses. That's cool.

Bottom Line

I'm *really* impressed. It's better than I thought it would be. The LG Optimus 3D is my main phone now, even though I also own two other phones with nominally higher spec. I love the 3D!

Here are some sample images in stereo cross-eyed format. Click through to see them in full size. Also below is a link to a video I shot on the LG Optimus 3D.
