Re: FUTURE OF 3D screens Rokit Phone limitations

Bill G
 


Nima, thx for sharing your input... you have the advantage of seeing many things in person, that most of us only see on the web.  Unfortunately, 3d must be seen in person to evaluate.

I am curious about your comment, that 3d "holo" type screens will be the salvation to 3d consumer success.  From my minimal experience with these screens, I find them very limiting in resolution, contrast and FOV, which are THREE key factors required to WOW the consumer.   You prob. have insights into the future of these screens, which we are not aware of.  Would you be so kind to expand your position on this?  I dont expect any trade secrets, just your opinion of what products have the best chance for consumer success.  Pls share resolutions, FOV, etc.  I am very interested. I am sure many other on this list are as well.

I spent several years developing optical viewers, and learned the hard way about the shortcomings of a high quality optical product.  Now, granted, I have yet to see any 3d views that can supersede the WoW factor of my optical views or even the low cost viewers such as 3dWords MF viewers.  I have mentioned many times on this list, a non optical product would be ideal for sucess, as the optics is a huge hurdle to overcome for a high quality product.  The Holo type screens avoid optics, but IMO, the Image Quality MUST be good enough to capture consumers for success.  Previous attempts that I have seen will only capture hardcore 3d enthusiast.  They all lack high enough resolution, contrast and FOV.

I am in full agreement with you on the pricing points u were justifying to a previous poster.  Some people expect, new, very high technology products to emerge for $99 retail... we all know how the technology cycle works, as million$ is pumped into RnD to produce just a prototype, the makers need to price to stay alive, higher in the begining, as volume ramps up, pricing falls. Considering these 3d displays are considered a sophisticated imaging product, the price points you are mentioning seem remarkably low to me already, which is encouraging.  So pls dont be put off by those comments on this list.  Many of us feel completely different.  For example, a hand held 3d viewing screen for $600, at this stage of developement is dirt cheap.  I am sure RED is not making a profit on their phones yet.  A nice camera kit can easily set us back $5k-$50K. 

Thx in advance for your insights...
Bill

Of course take my opinions with a grain of salt, I may of course be biased because I work for Leia.  That said, my day job will not stop me from sharing my unfiltered opinions in 3D, which of course I have very many.  The reason I left the VR industry and tried to work in 3D was because the lightfield display prototypes were the first I saw that made me believe that there was a path forward for consumer 3D.  Mark my words: if good 3D displays don’t win over consumers before good AR glasses do, 3D Displays will die and never come back.  Displays as a whole may even disappear.

Having tested a variety of glasses-free HD 3D phones since 2013, the IO Pro 3D is one of the best displays I have yet seen.

Yes, my comments don’t run counter to this.  I don’t disagree that the Rockit has one of the best lenticular screens I’ve seen, but the bar is very low when it comes to lenticular screens.  The overall experience is much better on devices like the New Nintendo 3DS series devices due to the very wide viewing angle, even though the resolution is much lower.  


Perhaps if you were more familiar with the arena of glasses-free 3D you would be aware that several 3D apps exist that work on the IO Pro 3D as well as on a variety of other glasses-free 3D phones.

RED chose another route making all of those apps incompatible with their system. As a result, the Hydrogen has sunk while the ROKiT is still in flight !

On the contrary, perhaps if YOU were more familiar with graphics software and how it must rasterize an image to prepare it for different displays, you’d understand that your statement above doesn’t make any sense.  Of course all KDX lenticulars and even some other lenticular or even parallax barrier screens have some intercompatible content.  The optical structure of their displays is incredibly simple, requiring just a horizontally interlaced image.  The nanogratings in the diffractive lightfield backlight of the RED Hydrogen One is significantly more complicated, which is why it’s better in many ways.  It has a much larger viewing angle, 3x as many stereoscopic views, can fully turn off the 3D display and switch to high resolution 2D, it collapses to monoscopic at the widest viewing angles for comfortable viewing, and a repeating pattern so multiple people can view it at the same time.  

Your ire should be directed at the app developers instead, they could easily support Hydrogen One with a simple implementation of the Leia SDK.  All the work has already been done for them!  Just add it to your software and voila.

To your point about staying power, the ROKiT phones have not yet lasted as long as the Hydrogen did, but I do hope it continues to succeed in its segment for a long, long time. 

 

"Budget as in "accessible" - something the Hydrogen One never was...


Hydrogen has been accessible in the second hand market since ~March of last year at $600, and RED even did sales where they’d sell it for $600 and it even went as low as $400 for Black Friday.  Seems quite accessible to me!  Though I agree, the original sticker price was a death knell for the Hydrogen long-term.  There does need to be a good 3D option for every budget, and I think dollar for dollar the ROKiT is an incredible deal.  However, you may be surprised to know this: on eBay, RED Hydrogen One phones are selling for the same price or cheaper than ROKiT.  I’ve seen Hydrogen’s sell for $200.  It’s currently being sold for $300 by Telcel, and has become one of their most popular phones, even compared to Samsung Galaxy.  We’ve been getting a flood of Mexican users creating incredible content on Holopix!  


If price is not part of the comparison between them, Hydrogen is truly better in almost every way in my opinion.  Significantly better processor(more than 2x more powerful in many cases), USB-C, ~2x bigger battery, better 3D display, better 2D display(no shimmering when in 2D), better 3D App Store with games and apps, significantly better cameras with 4K 3D cameras on the front and the back, and the list goes on.  ROKiT does however have a nice and slim form factor while Hydrogen is kind of a brick haha.

David Starkman -
 
Thanks for mentioning me.
 
Having the website http://www.civilwarin3d.com I have done a lot of work on these.  
 
The Library of Congress has well over 2,000 Civil War stereo images from the original negatives available on their site.  I have downloaded all of them at the highest resolution.  In addition they have nearly 30,000 stereo cards from the 1850's to the 1930's that can be downloaded here:
 
 
I took all of the Civil War stereo cards and provided them in several ways I also cropped them and realigned them in SPM to get as good of an image as possible.
 
 
Samples:
 
Original card:
 
 
Cross View:
 
Side by side (non cross view):
 
Anaglyph (Red/Cyan gasses view)
 
You can purchase the set here for $24.95:
 
 
I have produced a 2 set DVD (2 DVD's for anaglyph and 2 DVD's for MPO) that has all of the 2,000+ Civil War Stereo Negatives and have offered it at some NSA shows.  If you are interested in the sets, just let me know, they are $25 each or both for $40.  These are available in an MPO format for a 3D TV or in a simulated digital card.  All of the MPO versions are at the height for a 4K 3D TV.  All of the digital cards are 1920 wide x 960.  
 
Here is a list of all of the images on the Civil War negatives set:
Non - Virginia: (943 images)
 
Virginia: (1093 images)
 
 
Sample of the MPO version:
 
Here is a sample of the digital card:
 
I have restored and colorized several hundred and offer them as standard 3.5" x 7" stereo cards.  They are then mounted on 4ply matte board and have the look and feel of the original period cards in size and weight.  
 
You can find my physical stereo cards here:
 
 
Finally I have a digital colorized set of 100 images that you can find here:
 
Besides the LOC set I do have hundreds from the National Archives as well as a few other digital collections.  I have downloaded but not done any corrections on those.

SPM Multi Conversion MPO Output Options

Jeff Ewen
 

When the Output File Type is set to Independent (L/R) MPO, any input file(s) where the horizontal resolution exceeds 3648 pixels or the vertical resolution exceeds 2736 pixels will be resized down to an MPO file where the resolution is never greater than 3648 x 2736 pixels.

3648 x 2736 is the maximum image size of a Fujifilm W3 camera so this behavior is not accidental. The MPO files created using the Multi Conversion function would come out in a size that most suited copying onto an SD Card and viewing on a Fuji W3 camera (probably still the most portable auto-stereoscopic viewer around). 

I consider this a neat piece of intuitive coding but wonder if perhaps a second option is required where the size of the generated MPO file is not reduced down to the W3 ‘standard’.

The intention here is not to trigger a discussion about the merits of group member workflows that output any of the different file types that SPM supports, but to point out the issue.

I use multi conversion to generate SBS jpg output files that preserve as much of the resolution of the original source files as I can after being Auto-aligned.  The output files are typically around 25 megapixels in size (6240 x 4160).   Afterward I like to batch convert the files to MPO files for viewing on a TV without reducing them and use the Create/Split MPO File option in SPM which supports this multi-conversion.

I would like to have the option to convert my source images directly to MPO files using the Multi Conversion functions (Auto-Alignment, etc.) without the downsizing to the W3 ‘standard’.

This issue has been presented before in a thread by George Klein (SPM: How to produce MPO format without losing information) where he presented how to get around this feature and the need for the workaround fell victim to misdirection.


So may we have another option please Masuji San.

Re: The Root Of My Problem #1 and #2

Stereopix Net
 

I did not want to start a discussion about this, it was only a suggestion.

By 360×180 video, I talked about this kind of videos where the spectator can move the camera by itself (3 degrees of freedom).
I am not particularly into this, but it seems to be adapted to the kind of content you shared.
Here a (random) example if you do not see what they are: https://www.youtube.com/watch?v=0zXZIgnub6w

Although the video has far more than 100 degrees FOV, the player does the adaptation of field of view for you, which is like zooming in and cropping... but with the additional benefit that the users can choose the direction where they watch your video. You can optionally add a movement of the camera in the scene.

In practice, you can export two videos in equirectangular projections, join them and add a few metadata so that YouTube recognize it at spherical 3D video.
Some software probably have these operations embedded and I am pretty sure you can do that with Unity. Worth to give a try in my opinion.

Re: Restoring old Cirvil 3D War Photos

The dry (gelatin) plate was invented in 1871. By 1888 George Eastman introduced the first roll film "Kodak" camera...

But I'm always amazed that, in the 1850s, people like Frances Frith could create amazing images in e.g. Egypt using the wet collodion process (many of them sequential stereoscopic sequential pairs). The ambient temperature in Egypt could easily have been close to 50 deg C. And he kept the emulsion wet! :-)

Re: Restoring old Cirvil 3D War Photos

The wet collodion was popular in that era because it was about the only practical system to use "in the field".   It was still a real chore though...

Imagine having to coat your plate with sticky liquid emulsion, expose it, and process it, BEFORE IT DRIED!!  If it dried, the light sensitivity plummeted.  Silver nitrate stains on cameras (and photographer's hands) were seen as "red badges of courage".

The advent of prepared "dry plates" in the early1900's (or thereabouts) made a big difference.

I am very curious how cross viewing on 8k screens will be... specially with captures that net much better than 16MP per image.  Taking into consideration cropping and resolved pixels vs. native pixels, this would require capture sensors of about 30-50MP.  The cameras are available today, but the usual problem of syncing and achieving desirable base still exist.  The screens will be reasonably priced within 2 yrs is my best guess.  Of course this is for stills, video would prob. require a RED type system.

The point was that the Stereoid software can match the two eye-views when they are different in contrast and/or brightness. The tonal range of the best of the two views can be used to correct the other one to match it in terms of this quality without affecting the depth. This yields a better-appearing stereo pair that is easier to view.

Older stereo pairs, like Civil War stereo cards from the 19th century, often
have faded differentially, yielding a different apparent exposure and/or
contrast (dynamic range) between the left and right eye views. Stereoid
will match them exactly, as well as facilitate many other corrections.
When you are working with color images, or colorizing black & white images,
it will match the left and right colors exactly.

  In my first sentence I mainly state that the world being three-dimensional, our eyes perceive parallax.
 
I certainly did NOT take issue with this.  Its a 3d forum, I dont think anyone here would take issue with this??  


> With our unaided vision, when viewing a very close subject, our eye accommodation is on the near, making the far unfocused.


You bring up some good points in regards human vision.  But In my comments, I was specifically addressing the aspect of photographing the real world - rather than viewing it.

       why would anyone photograph and image, if it is not viewed in some manner??

Some great civil war stereo pairs.  I am viewing them on my 4K display, very impressive.
Its incredible how much rivalry exists with some of the shots, we are lucky to be in the age of digital, much can be corrected.
A few questions..
the best civil war images when scanned to extract maximum detail, how many MP is each image?  
Have you ever cross viewed on an 8K screen yet?

Re: stereopix.net - interlaced image output for passive 3DTV

Stereopix Net
 

I use a fairly common full HD passive 3DTV monitor (i.e. 1080p, a 24" LG screen).  When I switch the stereopix web viewer to interlaced, I cannot get the 3D effect to span the entire height of the screen.  Some part of the image will be stereo, other parts pseudo.  This is regardless of if I've switched to full screen display or not.  It is also regardless of what image I am viewing.  I would assume the web player would scale the output image to match the monitor resolution - but it is not working.  Can someone help me with this problem?

The viewer has a known bug with interleaved modes when one pixel of the page do not match one physical pixel of the screen.
This this the case on some high-dpi screens, and I just notice that it is also the case when I use the zoom function of my browser.

So try to remove any zoom in the browser (the shortcut is Ctrl-0 on Firefox and Chrome for example)

The current viewer is somewhat minimalist and a new one will replace it when I will have spent enough time on it.
Its completely different technology will allow to better handle this problem if all goes as expected.
In the mean time, I will check the algorithm to see if I can improve the compensation mechanisms with zoom factor in mind, but it is quite unlikely.

Re: stereopix.net - albums vs. categories

Stereopix Net
 


On the help page, the site mentions "categories" that can theoretically be added by the users.  I see no way to add categories?  Or are categories simply albums?
In their "photolab" users can create albums, to include their own images and optionally images from others.  Are the albums what the word categories otherwise refers to?

Maybe this part should be rephrased.

Categories are actually special public albums listed on the home page (and not-found pages).
Every user can add photos to them, but the list of categories is not modifiable (you can inform me if you think that one is missing, though).

Adding photos to albums (and thus to categories) is a bit tedious in the current version : you have to copy the URL and paste it into a form accessible via a button under the list of images in the album page.

When creating an album, one is theoretically given the choice for limiting image input to <just oneself, from others with a review process, and from others automatically>.  One is additionally also theoretically given the choice of limiting viewing access to the album by either <invitation only via a link, or everybody>.  However, on the page where you create your new album I see only one pull-down set of choices "Approbation: private / request / automatic"   
It is not clear what these three choices refer to (viewing or adding images?), and in any case it is not clear that both viewing and submission of images to the gallery can be controlled independently.

Oops. The viewing restriction was an initial feature that I removed because it was (to simplify) too buggy, but the text remained.

Also "Approbation" sounds self-explanatory to me, but perhaps there would be a better word to replace it.
Possible that the dictionary says that this word exists (with apparently the right meaning) but that in fact it is not commonly used.
