Probably a research project just to demonstrate the maximum they could do.
Don't see why they couldn't produce a phone size screen at 1200ppi.  Be
perfect in a phone viewer.

Thank you so much!


New NSA Survey - please take part.

J. CLAIRE DEAN
 

NEW NSA SURVEY

The NSA wants to hear from you, the members, and from anyone with an interest in all things stereoscopic.

After the overwhelming success of the NSA Virtual 3D Con, 2020, in August, and in light of the reality that virtual or remote content will necessarily be part of our future (at least for a while), we would like to know how best we can use this medium to bring the wonders of 3D to you.  So, we have created a short survey which we hope you will complete when you have a chance.

This survey is for everyone with an interest in 3D. You do not have to be an NSA member to fill it out. We want to hear from as many 3D devotees and potential enthusiasts as possible. Please share the survey link freely with your friends, local club members, on your social media pages, online forums, anywhere where 3D fans might be lurking.

We are asking a few questions about your interactions with the NSA, your interests in stereo-imagery, and your thoughts on the use of virtual platforms as a means of communication. Your answers will help us provide the programs, content and information that you want to see.

If you completed our feedback survey after the 3D Con, thank you so much. Your input was a huge help, not to mention gratifying – the 3D Con 2020 team truly appreciated all the praise you sent their way. However, now we need your help in moving the NSA forward in all of its activities. Your responses to this new survey will help us further. Please submit your replies by December 1st, 2020.

You can find the survey by following this link: https://www.surveymonkey.com/r/NSA_into_the_future

Thank you for your time and consideration.

Dual Link DVI-D to DisplayPort (or mini DP) cable source

robert mcafee
 

Connecting ASUS VG278H Nvidia 3D Vision monitor to laptop with HDM and Mini-DisplayPort only.  Must connect with DUAL Link DVI for NVIDIA system.  Anyone have suggestions for a cable or adapter source?

I see some adapters listed as Active.  It is not clear to me if Active in this case is equivalent to Dual Link.

Re: Holy Grail screens are coming

So... what are the chances that a 32K display finds its way to a phone or even to a VR headset anytime soon ?   Pretty low, I suspect.

Well of course, but its the 10K ppi technology breakthrough that will find applications...

First, for phones, no reason to really exceed 4K, unless phones become commonplace use in a viewer with lenses of less than 100mm fl, which I doubt...phones are phones, at most, to view 2d images, movies, i.e. no magnification.

This breakthrough was not for phones, it is clearly intended for the VR market. 
Here is how I see a simple example for VR..
each eye gets its own screen.  Lets start with horizontal width.
at 1" wide, @10K ppi = 10K horiz pixels.
1" would accommodate a wide range of IPD including young kids on the low end.
if the makers continue with 100 deg FOV (despite horrible resolution on the outer 60% of the radius) for the highly immersive feel, then it will provide the user about 100 pixels per degree. (10K/100).  I would suggest this is ideal to avoid seeing any pixels, or pixel patterns.  Using a 3:2 aspect ratio, each eye panel would be 10k x 6.6K = 66MP.   This would be impressive, although possibly not as bright as us fine art users would prefer.  Regardless, 66MP is a lot for content providers, however, this is easily resolved by upscaling the images, which is proven technology in 8K tvs.  Eventuall, larger capture sensors will be more commonplace in the future.  While upscaling is not perfect, it's still very beneficial.  The key benefit is, u will not see any pixels, even if resolution is a bit undersized for the pixel count.  But for Computer Generated content, such as games, this can be made to match the screens pixel count. 
The bigger obstacle is the graphics drivers, as the article mentioned... processing power needs a jump in technology to drive dual 66mp screens...but considering 8K tvs (32MP) are becoming the new norm, graphics drivers are not that far behind for 66MP screens.  Of course, the size and heat dissipation issue would be the biggest changes required for a VR headset.
So I dont think it's quite as far out as you suggest.
The technology breakthrough was the 10Kppi, not necessarily for use in a phone size screen.  When applied to smaller screens, the support hardware / software is within reach.

Re: Holy Grail screens are coming

Pierre MEINDRE
 

Interesting, it shows what can be done in a research lab.
To take it out of the lab would need a product that can be mass-produced and sold by large quantities.


BTW, nobody seems to be proofing these articles...
The Sony Xperia 1 II and its 4K screen delivers 643 pixels per square inch (PPI)
643 pixels per square inch is a very low resolution! Each pixel is 1 x 1 millimeter...
I've never seen a phone with 1 millimeter pixels!

Re: SPM Alignment

Laurent DOLDI (Toulouse, France)
 

I have compared SPM (version 5.28c) Auto alignment (Alt-A) on 2 stereo pairs : the results are the same using SPM internal code (with Better precision on) or specifying the location of Autopano-Sift (C:\Program Files (x86)\Autopano-SIFT-2.3).
One pair is correctly aligned, while SPM does not "see" the (large) foreground in the other pair.

BTW in about 10% of my 3D images (most taken cha-cha style), SPM ignores a parts of the image so it is not aligned.
Sometimes repeating Alt-A 2 or 3 times gives good results.

Re: Realist Photos

3DBob
 

I have scanned about 1000 realist slides with Epson flat bed scanners and they came out great. I detail this in this link: Re: Realist format slide scanner?: 3D and Stereo Photography Forum: Digital Photography Review

There are two issues to look out for: 

One is you need the Epson scanning software and have to be able to create a mask for where the images are on the scanner plate so it knows where to find them. You can do some tweaking in the Epson software, but using the dust remover is not a good idea as it leaves artifacts. Best to clean the slides first and use photo editing software to reduce dust, and also to tweak colors, contrast, etc. You need to make sure you do the exact same color/contrast changes to each slide, then save as imagename-L and -R. Then I process them in Stereomaker software. I now have them all on a bluray disk and they are fantastic to look at on my stereo TV and projector.

The other issue with scanning is the scanner has a "sweet spot" in the software that is mapped out by the slide holders that you place in the bed. Note these positions and also put a regular slide in a holder and measure, if you can, the distance from the slide to the glass, about 1-2mm. You must raise up your slides to match this distance so the slides will be properly focused, as the scanner usually has a fixed focused area built in for slides and negatives that are in a holder. Also you should have a complete cardboard mask for the inside of the scanner beyond where you have your slides located as the light from the unmasked area might affect the image. It's best to do one double image slide in each scan. It took me a couple of hours to figure this all out, and several days of trial and error until I had a process to scan, touch up and combine images into an MPO file for viewing.

You need to tell us how you are doing this and show us an example in order for us to appreciate what “not getting good pictures” means.

 

You can copy Realist slides using one of these 4 methods, in order of quality (best to worse):

  1. Film scanner
  2. Flat bed scanner
  3. Camera and macro lens
  4. Camera through the lens of a viewer

 

Photographing through the lens of a viewer has a number of problems, including the quality of the lenses (not as good as a macro lens, OK at the center, distortions at the edges, quality of light not controlled, etc.)

 

Using a camera and macro lens is what I use for “quick and dirty” job. See attached picture that I photographed yesterday. Used a GX8 Panasonic camera (M4/3 format, not DSLR) and Olympus 30mm macro lens, over a light table. Only cropping was done. Not ever sharpening.

 

The best results are obtained with scanners.

Currently I can't my desktop crashed last night leaves me with no computer to scan with.

Don't when I'll get it. Repair shop says up to two weeks.
