Re: Just got my Looking Glass Portrait - a couple of questions

The HDMI port on the computer side is not required.
But to be able to use the HoloPlayStudio software, it must "sense" that the device is connected with the "HoloPlay Service" (a kind of driver).

I'm using an older laptop (> 5 years old) without fancy video card, no HDMI and no USB-C port.
Fortunately it has a DisplayPort output and I use a cheap DisplayPort --> HDMI cable, like this one:
https://www.amazon.com/Moread-DisplayPort-Gold-Plated-Converter-Compatible/dp/B07KRXWVWG/

I use a simple USB-A - USB-C cable to connect the LKGP to the computer (then seen as an external storage)
Like this one :

(need for HDMI port) I am pretty sure you can but I like to use mine so I can test the files first.

I heard too many people including LG representatives say that an HDMI port is required on your computer that I really need to hear more from people who can connect the LG Portrait to their computer without an HDMI port !

1) Can anyone point me to a simple set of instructions for going from starting with a stereo pair in StereoPhoto Maker to convert to the type of file the Looking Glass Portrait can use?

I did a workshop on the first steps.

2) I do most of my work on a PC laptop that has no HDMI interface.  Is it necessary to use HDMI or will the USB cable adequate to transfer data to the LGP?

Yes.

1) There is a detailed thread about this in the 3D Tablets group here:

https://groups.io/g/3DTablets/topic/looking_glass_portrait_viewer/83017042

Both Steve Berezin and Dave Comeau also did YT clips about that.

2) You need an HDMI port to transfer data.  Missing that, you would need to have a USB-C port and a USB-C to HDMI adapter.  USB-C alone would just power the LG Portrait but not do any data transfer.

3) Once your files are formatted for the LG Portrait, you can download them to it and use the Portrait as a standalone display.

I have used it handheld...

Well that's good.  One of the things that can really improve your photography is using a tripod.  But unfortunately even when I am out for the purpose of just shooting photos, I still seldom use one. I need to learn to have more patience.

So I'm picturing myself walking around with a more compact version of this rig.  Certainly not super convenient but doable.  Then for some reason I suddenly envisioned George running through the woods, clutching the rig in front of him with both hands.  Now that would certainly be an act of dedication!  🙂

A stereo microscope is a very useful tool and not very expensive. I use mine often, for soldering and whenever I want to see something in good detail. Usually at the lowest magnification and with a good strong light.

I disassembled an a5100 and found internal points to solder to, but they are so tiny,

 

You can easily see why modern electronics are now assembled by robots.  I considered getting a 3D microscope for doing really fine soldering work, but I doubt my hands are steady enough to do the job.

Do you have details on how you wired these up?

There would be value in the abilities of somebody who can solder to these points.

Replying to Bill’s questions, I think the cost of the rig the way I set it up with Small Rig components was a few hundred dollars. The same components can be used for a side-by-side mount that is twice as long. And of course it can be extended further with longer rods, which can also be joined together. There are more economical set ups one could do. Also, it’s only as big as it is so that it will do hyper‘s. If that’s not needed, it can be more compact. I have used it handheld and on a tripod. With the cameras and batteries, it weighs 5.8 pounds.

JMH/trivision3d : well done, this rig looks very professional, but yes, too big for some situation.

There was a discussion some time ago on a French 3D list of cinema professionals. They use for wide angle lenses, a 4K resolution and a foreground at 4m (for example a car), a center distance of only 20mm between lenses. I replied that amateurs with the "thirtieth" rule which does not take into account the focal length ... meant that amateurs with much larger distances between lenses. The thirtieth rule gives for any focal length for a 1st shot at 4m ... an adjustment of 120 mm center distance. They laughed and answered that the 3D of the amateurs is certainly way too strong (especially way too deep) ... but "magic" for their eyes of clubists become very elastic. One of them privately sent me the image bellow showing cameras with center distance between lenses from amateurs... who amuse them.

Okay, but the pros do not do better than the amateurs on the other hand in projection ... they also regulate them too much on a screen (post production for) the gap between two homologous points of infinity. So for my partners and me, it's the blind who laugh at the deaf!
Anyway... The pros use beamsplitter rigs (mirror like prompter).

From small...beam spliter rig for Go-pro sync + anaglyph control monitor

To very big beam spliter rig


I'm between the two worlds (Amateurs Vs pro 3D cinema)... as I made more than 100.000 stereo photos (slides to digital and conversion 2D/3D), I'm now starting in 3D video... so I'm doing with my little means (build myself my rig beamspliter and find 4K cameras (with a lot of lenses, even zoom, I-R) which are suitable + Sbs sync circuit and micro computer to manage everything. I still have to adapt a trigger button to the microcomputer (because it's a monitor connected to the computer... and you have to indicate the duration of the shot... so for the moment a studio cam). Lithium rechargeable battery to be foreseen, or even a small solar panel to recharge.


My cam now is ready and first shoot Sbs 4K L + 4K R well done. The interest of the circuit that I found with difficulty... as well as the cam... is that there is also possibility to record the colors by one of the two objectives... and a deptmaph by the other. This opens up possibilities for tablets and Light Field monitors (Holo Play, etc.) it takes a large number of perspectives (Holo Play 45)... so it takes dephtmap, because how do you want to have a small interaxis with 45 synchronized cameras. The future of 3D (shoot and 2D/3D conversion) is with Dephmap.


It can be used with appropriate lenses, to scan View Master discs in twin 4K. On the other hand, the stereo circuit of synch Sbs does not allow to change the FPS speed of recording (for example accelerated to have a slow motion in broadcast) 😕

I still have to connect it now to my rig beamspliter bellow which for the moment uses only two Sony V1 RBT synchronized (in photo the resolution goes up to a bit under 2K, but the video is much too weak)

Indian Bollywood 2D to 3D conversion

forum@trivision3d.com
 

JMH/trivision3d : Hello, a 3D professional (rig beamspliter designer, see file)
sent me this Sbs link on a not so good 2D/3D conversion. I wonder if the 2D/3D conversion software used by Phillip Heggie could greatly improve the battle of this Hindi Bollywood film... whose conversion (old method) in the link below is not so good. But this battle has nothing to envy to the one of the Lord of the Rings.

https://www.youtube.com/watch?v=BoWovgYfuA0 <https://www.youtube.com/watch?v=BoWovgYfuA0> <https://www.youtube.com/watch?v=BoWovgYfuA0 <https://www.youtube.com/watch?v=BoWovgYfuA0>>

This is a very difficult subject to test the "A-I" automatic conversion, as there is movement all over the place. may be Philip can try to meet the challenge?

Thanks, Philip.  It's great to see this old classic resurrected.  I was afraid I would never get to see it in 3-D.  I really appreciate all the work you've done!

No I’m finished with it for now, it does go out of sync briefly in a few spots and is a mix of VHD left Bluray Right when there is no dialogue

And Google AI 3D when there is dialogue to remove Japanese burned in Subtitles.

Philip, thank you so much for posting this!  This has always been one of my favorite off-beat movies, but I've never gotten to see it in 3-D.  I notice that the opening credits are somewhat fuzzy in the left eye, and there are various places in the movie where, I don't know, it loses sync or something (?).  Are you planning to do any more work on it?

Thanks,
David

There is an extensive discussion about a compact Z-bar being offered by one Ron Anchak on the Sony 3D group.  However, last I heard, David Gadbois was never able to get a clear response from Ron as to whether he was actually willing to make anymore.
