Google cardboard with DCS world

[sniperwolfpk5]

SkateZilla did you experienced on both google cardboard and others (Oculus/Vive). How different both are? As I saw you in various VR threads helping people.

As my rift was postponed, too, I ordered a cardboard which I use with moonlight. But my TM Warthog throttle is not working properly with this configuaration. It stays at about 20% thrust or bounces for seconds to full throttle. Of course I tried different USB ports.

Anyone experiencing this also?

Had the same problem - a new control device was added which automatically was bound to the default axis - just delete the axis category for the device and you are good to go

Thx, didn't think about that . Will try it later.

Yes, also had the same problem. I guess the best solution is to follow these instructions:

https://github.com/moonlight-stream/moonlight-android/wiki/Setup-Guide#using-a-gamepad-connected-to-the-pc-instead-of-the-streaming-device

That gets rid of the extra controller, which messes up your configuration in DCS.

I have a question because the ipd...

When I render dcs in stereo for my iPhone6 (4,7") the distance between the left and right right center of view is 5,3 cm, but my ipd is 6,4 cm. So, with the cardboard on I always have to "cross eye" to focus on a distant object, and that makes my eyes tired.

 

I have played around with the viewDx parameters in the stereo.lua

I have set the eye_shift to zero and increased the viewDx (which I mean is the center of view, correct me if I'm wrong) for both eyes until the distant objects like clouds are separated by 6,4 cm. Then set my eye_shift back to the ipd wide and it feels... Better

 

Has anyone done something similar yet?

Well I have 5.5 inc phone. I haven't face such issue with basic cardboard. If you use TrinusVR you have full control to set your screens, in your case you need to set x-distance in TrinusVR. I can't say much until I get my z4 VR headset which has IPD and focus settings.

Google cardboard with DCS world

 

Can't use trinus, there is no version for ios atm.

Setting up ipd on the cardboard doesn't really change the ipd of the image, just the lenses so on smaller smartphones this could be a problem.

After 2 hours in a mission I have had this feeling. Now it's far better - when I let my focus shift between near and far scenes it feels more natural and all feels bigger not so toyish

 

But now, zooming is another story... Need more tweaking

 

Edit : is the viewDx parameter the shift of the center of view?

Maybe I will try another solution with the viewport sizes...

 

I have tried again something, I was on the home screen of my iPhone and put it into the freefly vr headset, shut one eye and look at the center of my view - straight ahead, then I shut the other eye and do the same - I was looking at the top of my notice app and with the other eye on the page indicator of the home screen - then I measured the distance between this 2 points and it was exactly my ipd.

You have some great findings. I can understand it is hard with small phones, as you need a way to change display sizes on actual screen like we do in TrinusVR.

 

How much FPS you get what are your system specs?

[Einherjer]

I have no heavy impacts of the performance when rendering in stereo mode... It varied between 40 and 110fps on 1080p with a sandy bridge i5 and a gtx 770 - but I have to say I am not really sensible for motion sickness, so playing 2 hours with 40fps, some lags and a not linear head tracking is no problem for me ;)

[Einherjer]

Update : the viewDx parameter seems to be correlated with some kind of convergence, so that is not optimal for shifting the center of view.

 

So, next try :

I set my X coordinate for the left eye to -100 and for the right eye to screen size x 0.5 + 100, this gives me 200 pixels separation between both view ports - I can't see the separation with my headset but it works well now!

 

Next thing to try :

Setting eye_shift for the left eye to zero and double the right, maybe it affects the shift of the mouse cursor?!

[sniperwolfpk5]

How is the mouse usage. Are you able to use it properly? As it has offset issue

[Einherjer]

Will try it later, hope it will fix this issue.

With the Stereo Monitor Profile use EyeShift, just make sure it's done correctly.

 

Ie:

Left View:

		  eye_shift = -0.032

 

Right View:

		  eye_shift = 0.032

 

 

Note the Left View Value is Negative, while the right one is not.

 

IIRC I **THINK** that value is in Meters, so -0.032 to 0.032 is .064M or 6.4 CM or 64MM

[Einherjer]

That's what I did first - but the vanishing point of the projection still seems to be in the middle of the viewport, so 5.3 cm no matter what eye_shift I set (near objects are affected)

But maybe I am just wrong - will test it this evening again

[SkateZilla]

Ahh,

Adjusting the start Position for each eye will give some separation.

 

IE: Assuming it's 1920 width and you want 120px in the middle.

 

Viewports = 
{
    Left = 
    {
         x = 0; -- (Starts Rendering at 0 / Left Edge, and leaving 60 pcs on the inside edge blank)
         y = 0;
         width = 900; --screen.width x 0.5 - 60 (1920 /2 -60 =900)
         height = screen.height;
         viewDx = 0;
         viewDy = 0;
         aspect = screen.aspect / 2;
  eye_shift = -0.032;
    },
    Right = 
    {
         x = 1020; --Starts Rendering at +60px into the inside edge to the far outside edge).
         y = 0;
         width = 900; --screen.width x 0.5 - 60 (1920 /2 -60 =900)
         height = screen.height;
         viewDx = 0;
         viewDy = 0;
         aspect = screen.aspect / 2;
  eye_shift = 0.032;
    }
}

 

 

Might need to Adjust Aspect to match render size (900/1080 = .83333), so change to .8333

[Einherjer]

Yeah that's similar to that, what I did (see above), I just shifted the fiewports out of the screens, works also.

 

edit:

 

Testet eye_shift left zero and doubled the eye_shift right -> looks absolutly the same (a few degrees rotation to the right, which is not noticable especially with head tracking) and the Mouse courser offset problem is solved!

Sounds Great! :thumbup:

"Unfortunately" Im on holiday this week but I'm looking forward to try it out.

[D4n]

Just ordered cardboard, will post here when I test it! :)

[D4n]

Cardboard not arrived yet, BUT, few questions :

 

How can I set up moonlight to use the internal movement sensors of my Xperia Z device? (To do headtracking with its internal dozens of super sensors), as FaceTrackNoIR has problems with me/my glasses/latency delay apparently (although PS3 Eye) ?

 

Or does Google Cardboard (Android) App run in background and use sensor data while Moonlight is running? :)

 

 

By default, moonlight will go via wifi even if you tell trinus to use USB tethering.

 

Wait, how can I use moonlight via USB? :) (Doesn't work for me and Xperia Z ? Disconnecting as soon as I disable Wi-Fi... :( )

 

 

I see moonlight requires GFE to be installed, so I won't be taking that route anyway

 

Wait, what's your problem with GFE?!

[sniperwolfpk5]

Well I can't say more about moonlight but I can talk about Trinus and sensor options in Trinus. You have a different sensor options that you can use.

• You can use OpenTrack which is free and a much better project and support than FreeTrackNoIR. To use your mobile sensor you have to select Free Pie UDP Receiver from Tracker dropdown (openTrack). I think it will install Free Pie andriod app directly into your phone. If it didn't install then you have to install FreePie app for your andriod phone. Thats it now your phone is your headtracking device as well.
  
• Select FreePieIO from sensor list (Trinus). I think it is using same FreePie app to track your head movement using your phone sensors.
  
• With opentrack you have tons of other options one of them I explained above. You can use PontTrack and you don't need to select any sensor in TrinusVR.
  

[D4n]

But Trinus is some kind of trial version?

[sniperwolfpk5]

No it has paid version as well. The server is free but android app has two versions free and paid one

[WindyTX]

Ok sorry if this was explained but.

 

1. I am in a hotel so wifi is crap trying to go via usb. Moonlight doesn't seem to let me connect via wifi. Do I need Trinus as well I am using a laptop with a 970 and have gfe running in order to usb tether my phone is Galaxy s7 edge.

[sniperwolfpk5]

I don't think so if you are using stand alone moonlight then you don't need Trinus
