One Projector, 180 degrees

[OmniAtlas]

Setup at FlightSimKL



Looks pretty amazing. I talked to Nat (FDS) -- its one projector, one FSX window view zoomed out. Not really a true 180 view, but looks impressive nevertheless.

Has anyone setup a similar system with 1 projector?

Looks amazing. How did they do it? Warping software?
On my previous job/work I made a screen that was curved with one projector. I used a plexiglas sheet with rear projection film, and first surface mirror that was curved with the ability to make small adjustements. I dont remember what the radius was, but it was awesome to use a curved screen with Xbox and PS3, with DLP 3D.
Incredible depth with curved screen and 3D. I used a Optoma GT750 projector.

Yes, if you look at the lower left corner you can see the text is warped.

I don't know what software they are using; probably NTHUSIM.

I would like to setup something like this -- perhaps with a BenQ W1080ST projector; it would lead to considerable costs savings (1 projector vs 2)

However I am sure the lateral views are completely not in ratio.

I have also seen 2 projector builds -- only downside right now is the resolution will be terrible, I'll only be able to afford 2x 1280x800

Hrrrm, interesting looks like he's doing around 120 degrees or so. My main question is how are they handing the focus range on the screen? There has to be issues at the center and edges with clarity for text. You can hide a lot of issues in a 640x480 picture. What are they doing to not lose pixel height on the projection? Using an anamorphic lens or bouncing off a mirror? In my experience anything over 110 degrees FOV has depth focus issues. My current personal screen is doing 100 degrees per projector -- 90 per projector + 10 degrees of blend.

Its a 1080p projector
FSX is zoomed out to about ~ 100 FOV

I don't think text will matter that much for the visuals?

I'm just wondering if anyone else here has done a similar setup.

[BHawthorne]

It'll be fine for non-text for the most part. Your brain doesn't process that the outer edges might be out of focus a little in a setup like that. At issue is a lot of the FSX menu is going to be towards the left edge and you'll have problems reading the menu. Only a minor irritation, not a game breaking thing though. He has to be losing some pixel height on the projection if he's wider than 16:9 aspect ratio. My guess is his real viewable area is probably around 1920x768 with pixel height projection lost. Not really a bad issue, but I hate losing any pixel height at all with wall sized projection. His setup is acting similar to a two projector 1024x768 setup without having to deal with the center blend. Innovative way of doing things if the focus range is bearable in the setup. He's really pushing the limits of what the focus depth on a projector can handle though.

The other thing is, I think wants you put an overhead, or a shell, these visuals will be impossible unless you have a very high ceiling.

If the viewable area is only going to be 1920x768 would be more wise to spend the money on 2x720p ultra short throw projectors?

I was going to go with a 1080p projector because I wanted it to double its use for cinema viewing, and perhaps a golf simulator.

120 degrees with a single 1080p projector is plausible like the previous examples show. The only thing at issue is the unknown focus depth issue. It's one of those things that would have to be addressed by simply experimenting to see if it's ok for the particular setup you have in mind. There is risk there but the reward is not having to deal with edge blending. Personally, if a single 1080p projector works I suggest it over the logistics of using two 1024x768 projectors. You'll still need pre-warping but do away with edge blending. I'm very weary of anything under 800p for the pixel height so I'd suggest losing as little projection height as possible in the screen design.

Thank you for the advice bhawthorne. I worked out some numbers with the benq 1080st last night with the benq calculator and it came up to about a 133" screen at 2 m.

Have you tried throwing a projector at a corner wall with the center screen midline? I may attempt that before purchasing/making a curve screen.

If i was to use 2 projectors I am not too worried about the blending; I have taken a look at some of the immersive pro videos and I am very impressed with their auto calibration.

According to the author they will be building in fsx/p3d support soon.

I use two projectors on my personal screen, 2560x800. I think the resolution is ok when playing racing games.
These are Vivitek QUMI Q5. The big downside with these is that they use a bit time getting in focus.

To further explain, it really depends on your end use. Simulation, gaming and video content will look ok with the resolution. If you're doing spreadsheets on the desktop it'll look bad. Reading of text is a problem with that resolution in a setup like this. Be mindful that in an ideal world we could all afford BenQ W1080ST. I have two of those on my to buy list this year. I'm saving a bit up each month to get them. My Optoma GT720's are showing a bit of age after 3 years of use. 2560x800 works for what it does, but it's not ideal. It's ultimately a compromise made to keep things affordable. If 2560x800 is really a game breaker for you, I'd save up over the next year for two BenQ W1080ST instead. No need to rush into the build. Take time and don't compromise unless you have to. It's important that the end result of the build best suit your computer habits and needs. I've seen a few people where they compromise on the build based on tight time or budget constraints and are frustrated with the end results. I wouldn't want you to go through all the trouble of a 2560x800 build and not be happy with it when you could wait a bit longer and do a 3840x1080 build instead.

I'm glad you are also intending to purchase the W1080ST -- then it really must be worth the investment.

I would like a multi-functional use for my projector; not only flight sim, but also cinema viewing. I think doing word processing on a 100" screen would be overkill

Perhaps I will get one W1080ST, and then invest in another one further down the line. It should hopefully drop to the <$1000 level in 2-3 years.

I don't think 3D will work with 2 projectors edge blended?

Hardware spanning via adapters does not effect the ability to use 3D Vision. Also, Nthusim edge-blending also does not effect the ability to use 3D Vision. Both work with 3D Vision kit. It treats it as though it's a single display with Nvidia 3D Vision enabled. Be mindful that the hardware spanning adapter must have the bandwidth to lock 120hz though. That is why I used the MViewer box and not the DH2G box for my previous dual-projector Nvidia S3D setup. I believe I tested the Zotac adapter for 2560x800 120hz awhile ago but forgot my findings. They're probably in a post somewhere in WSGF though. Be mindful that the W1080ST is going to have a lot more bandwidth requirement than a 800p projector so I have my doubts on any hardware box spanning adapter having the proper bandwidth requirement to enable 3840x1080 120hz.

I use my 180 degree screen for almost everything, not for writing large documents, but another small tasks.

The W1080ST looks really amazing, but the price in Norway is awful, 1530usd (todays exhange rates).
Like Bhawthonre, on my previous screen build I used Optoma GT750, the picture was good enough for gaming and other small tasks, like searching for game fixes on WSGF.

Warpalizer's edge blending also support/do not affect the picture when using 3D.

I don't think 3D will work with 2 projectors edge blended?

Depends upon the S3D type used and the projector used. With the GTX770 and GTX780 released I might pick up a used GTX670 for cheap so I can do some testing this month. I feel a bit unarmed when I currently only have an AMD video card to test with. I really need both AMD and Nvidia for testing.

I'm relatively new here, but was following this thread and thought I'd chime in.

We are doing a gaming room for an event here called the Parade Of Homes.

We have 2 setups - one of which is a 12' x 5' slightly curved screen (comes in about 2'-4" on each side of the 12' width - not sure what degree that is). The purpose of the slight curve is the builder wanted it to be good for movies as well as gaming. The reason for the height was based on the two projectors set at a 4:3 ratio instead of 16:9.

We bought two of the Benq W1080ST projectors, and ended up using the Immersive Pro software with the auto-adjust software. The BenQ's did a very good job of supporting the 4:3 lower resolutions.

Very happy with everything, the software takes care of a majority of the work, can use a standard Logitech webcam (which we already had). You still have to fine tune it, but games are awesome and we downloaded some sample 4K movies from Youtube and playing them with KMPlayer, which will stretch the image and it's very crisp. Search for "Bees in 4k" on Youtube and set the res to Original. Windows looks a bit hinky, but games and movies are our priority. In watching video, the stretching is not noticeable.

Immersive Pro did a perfect job on the edge blending, so the final tweaking was more about keeping horizontal things horizontal. Just don't think that it's point the camera and 2 minutes later it's all done, just a bit more work than that.

I promise to post pic's later, but am thinking this should be under a new topic if people want to hear more.

I am very interested in a single projector solution, but not for cost as much as supporting XBox One and PS4's. From what I understand they both can support 4k resolution, and possibly any resolution you set below that. That being said, our focus is PC gaming but believe our clients will also want the ability to use consoles as well.

The only thing that would support an XBOX One or PS4 would be a hardware solution. There is no option for that in the consumer price range.

IMHO, distorting aspect ratio is always noticeable unless it's close to the aspect ratio of the source file. Also might create your own thread for your experience with your build. It'll get lost buried in another topic if you post about it this thread.

[dblair871]

Thanks Brad, I appreciate the input. You are the reason I started following this forum!

I will start a new thread for my builds. I'll try and put a couple photos below as "teasers".

In context of this threads topic, what if we took the output from a PS4, where we could set the resolution to whatever we want (4K?), then that fed into a PC through a capture card, then back out where the Warp and Blend software can do it's magic. This is all just theory at this point, but even my son who considers himself and his friends part of a "PC Gamer Master Race" is looking at the new consoles with some envy.

Also, as to the aspect ratio, I thought the same thing and since our focus is gaming, we would see movies with the black bars. I honestly didn't put much thought into it, but surprisingly things look pretty good. May have been dumb luck.

I"m not sure the photos will show up, but the curved screen looks fantastic, the 3 LCD TV's have incredible detail (I tried two of the new GTX 780's in an SLI, only to find out that this specific model can't do both surround and SLI - you have to go up to the Titans or down to the 680's). Even with one 780 working hard, the games are working at their highest resolutions.

Thanks, the reason why I had Skip add in this forum is that there are so few places to go for this information. It's super important that there be public forums to help make these sort of builds more plausible. Given enough people's input more imaginative builds come about. The downside is it spawned competition in a very niche market, but in the grand scheme of things competition is good. It keeps things evolving with new features.

Input card -- Yep, but that is a bit of a convoluted way of addressing it. I'm not sure of any card that allows for UHD input. Piping the console through the pc will probably induce latency from the initial transcode on the input card. I know MViewer had a blending box but it was expensive compared to the software solutions.

No worries. I'm a major Trekkie. I have a TOS movies era uniform I used to wear to sci-fi conventions.
