how about a vveekend vvorkshop about this? who should keep it?

omg! cool

boom

Thanks tonfilm,
Trying this with an Oculus DK2. Installed SDKRuntime 0.80. OR Configuration utility seems happy but OpenVR girlpower never detects HMD.

Have I missed anything?

@tonfilm
everything works fine in SteamVR/vvvv with oculus runtime 0.8 + latest Leapmotion Orion Version: 3.1.3+41910...
btw failed with the newest v1.6.0 oculus runtime (even if gtx 780ti should work)
now of course the challenging part is to make vvvv patches that runs at 75/90 fps ;)

@ggml, yeah i saw that too

works amazing here

@andresc4 you can translate a grid on z axis and connect it to hmd pose transform

btw:
any chance for a dx11 screenshot node for virtual patching purposes ?

The haptic pulse node seems a little odd, it only seems to work when the power is around 0.06 above that and you can hear it but not feel it, it's also quite weak, is that as high as it goes? I want a massage :)
Also the node goes red if the controller disconnects.

Thanks tonfilm and supporters!

The Poser node is CPU intensive (8000 ticks in debug mode). I can't get a perfect 90fps with the OpenVRdemo..

When WaitForSync=0, Poser is 100 ticks, perfect 90 fps.
But I can see the double lines in motion...
The motion is perfect only with WaitForSync=1.

Any idea for a workaround or other ways to decrease the Poser CPU consemption?
What is the role of WaitForSync?
thanks!

hi tonfilm,
Thanks for your answer, but I can't get good results with the OpenVRdemo at this time (it's an exageration: results are perfect, but after drawing a few lines in space, CPU is overcharged, and framerate too small...)
With this CPU budget, it's hard to develop more complex applications.

If I understand correctly (and for me it's very abstract), OpenVR use a fonction called WaitGetPoses()(the VVVV WaitForSync Poser Pin?).
This fonction seems to wait for the position of every tracked objects in the scene and it's necessary for a perfect fluidity and avoiding any judder effects.
But it has a very high CPU cost.
Seems to be a frequent OpenVR concern on Github.https://github.com/ValveSoftware/openvr/issues/64
An OpenVR user talk about rendering GetWaitPos on a specific thread to gain performance, and not to block the others CPU process.
A thing like that would be possible in VVVV?

Thanks,

Hi microdee,

Thanks for your clear explanation!

So the (scary) question is:

There is no way to use Vive+VVVV without judder and/or low framerate, regardless of your hardware specs?

hello guest and @microdee,

as you can read on the openvr github and steam threads about WaitGetPoses, there is no way around it. but calling it as soon or as late as possible in the frame is the next thing that will be added to the pack.

also microdee has developed a compositor node that has a DX11 texture input to avoid the resource pointer read back... i will try to merge that soon.

@microdee ok, do you know in theory how to avoid resource pointer read back, or should i contact @vux for more details?

mainloop events is in the making...

@tonfilm maybe you can do the readback similar to here (https://github.com/elliotwoods/VVVV.Nodes.ReadBack) not sure this is the ideal way for reading back only 1 pointer, but at least it's threaded.

@microdee and others, as of V3 the WaitGetPoses is now by default after the vvvv frame, so shortly before the next frame, which is recommended by valve. if Sync After Frame is off, the call is right before the vvvv frame. you can check what works better for your setup...

@catweasel please try haptic pulse again, i think i fixed a little bug and the node is now spreadable. it is common to trigger the pulse in multiple frames (MonoFlop or so), the power pin is the duration for one single pulse from 1 to 3999 microseconds, so max 4ms.

@guest: use R8G8B8A8_UNorm (you can try sRGB variant too) texture format. only dx11

Hi everyone,

I'm new to vvvv,so maybe this question is very obvious, for that I am sorry.

I am trying to get my Rift DK2 to work, It works with the SteamVR calibration etc. - so far so good.

I am trying to use the example patches in the

VVVV\vvvv_45beta34.2_x64\packs\VVVV.OpenVR\girlpower\01_OpenVRDemo

However, when I open the demo patch, I have several 'red' (unloaded) objects.

I read the Using Adddons page, and I have gotten the impression that placing the openVR folder inside packs should be suffienct for letting vvvv see the content in all subdirectories.

Is there a setting which let me direct vvvv to the sub directories of the OpenVR 'nodes' folder?

thanks a lot! :)
Lasse

Hi Tonfilm,

Thanks a lot for your answer, I think my problem was with me installing the Oculus SDK and SteamVR wrong. Anyway - after uninstalling everything and installing again it works with the newest version of oculus sdk (1.8), steamVR etc.

I should have deleted my question, but got carried away in the new good energy eager :)

Have a good evening!

@mrboni
I think you can set chaperone mode and color in the steamVR settings with your remote

@quaddro

for your fist question, there might be a solution but i have to check that... you can somewhere tell OpenVR that the application is a background application.

the patch in vr patch is only displaying the XML of a patch, you cannot interact with it really... i might remove that.

@andresc4

OpenVR does something similar for you... i think it's currently not as good, but i read somewhere that there will be an update soon.

@tonfilm

I mean this
"The hardware requirements for ASW are modest. This functionality has been enabled on all current-generation AMD GPUs (RX 400 series) and previous- or current-generation Nvidia GPUs (GTX 900 or 1000 series)."

I have a 950 on a notebook and I would love to use OpenVR without my big desk pc

@tonfilm according to nvidia, that should change with the latest 10 series GPUs, where they have dropped the mobile naming and claim that the mobile versions are within 10% of their desktop counterparts.

Hey guys, how can I stream VR player on the screen with chromakey body? Like on that video:https://youtu.be/Ikz5uJ0KE3w . You see, that man is playing the game,and we also can see his body. I understand that he has something green or blue befind him, and other "VR operator" shooting him and stream it with his body? How can I do it?

Is there a solution to the post from

?
Does using a 16bit texture format work?

Using a 16bit texture format didn't help..
Can't test anymore, I don't have the hardware here!

@dominikKoller with Intersect (EX9.Geometry Quad) node it is easy to get the XY coordinates of where the controller is aimed at (and create a pointer that starts at the controller and ends at the intersection point with quad). It's then easy to map interface texture onto the quad and feed the interface with XY and controller interactions. Could be a HTMLTexture (DX11) and I guess that allows you to create interactive interface and read its state.

Nodes are missing for the Patch in VR patch, is this supposed to be working now? Or what are you using to do some patching while wearing the vr set? I tried with the camera but it is too low res, maybe screenshooting?

Simone

EDIT: https://sourceforge.net/projects/screencapturer/files/ this one works at least so it is possible ot tweak the scene wearing the vrset.
I am really missing a zoom feature here for vvvv though...

I'm facing some lag in the vive headset view after installing the new version (18/01/17) at every movement, as if I'm still at 90 fps. I mean every movement duplicate the content for a short time. It creates a bad feeling and a real vr sickness. this was not the case in the previous version.
Maybe someone as some idea how to fix it?
Many thanks

HI tonfilm. Thanks for your reply
just made the try before to read your answer, downgraded to previous pack and relunch my patch and the issue is still there. but I did not have this behavior before ( i would obviously noticed this ). I tried to change the texture format to 16bit in the renderer but it made the "movement delay" effect worst than in 32bits.

@elektromeier, many thanks for your help, just tried this and removed the renderer for preview purpose but nothing changed in the headset.
maybe the stutter was a bit faster..

@mediadog
i'm using nvidia gforce 1060 everything was quite perfect before.
you are right the head rotation is quite smooth and no stutter in this case, but when moving ( walking or moving the controllers) the things are going worst. it seems to be a position refresh issue, like a delay between the real position of my controller and the position received by the computer. as the effect appears bigger when moving faster.

At least with my setup, this is not only a problem with this plugin. I just tried "The Body VR", and if I set the rendering quality to high, the framerate drops, and I see the same exact double-imaging on movement. So this seems to happen when the rendering framerate drops below the Vive display rate even with Vive apps.

this pack is amazing, thanks for sharing! I've been using these nodes while prototyping my last project. i hooked up the vive with blender through osc using vvvv. for the final demo i turned towards unreal engine as the rendering features and accessibility were much more robust.

www.vimeo.com/hhid/augmented-light

moving on to my next project i was wondering wether this pack supports the htc vive tracker by any chance?

hey tebjan, thanks for the reply.

i ordered one which is supposed to be delivered in early may. i'll let you know if they work out of the box. i was just curious if anyone else already gathered some experience with the trackers. in case they don't i'll get in touch with you (you are right, i'm currently doing my interaction masters degree in weißensee)

the directory paths in ViveLighthouse and ViveController nodes should be accessible as pin since not everyone chooses the default directory for installation :)

left and right touchpad visualization is reversed in ViveController node.

sorry for spam.. :)

Is there minimum PC spec that is recommended? does it run on windows 10?

Thanks

@ottomatic it works happily for me with a GTX 960, even a GTX 870m in my Sager laptop. Of course actual results will depend on scene complexity. I think if you are able to run things like TiltBrush or Night Cafe OK on your PC then it should also handle this.

Hey all, this pack is just perfect. It works very nicely with 3d scenes and is easy and fun to use!

I have a small problem using this pack:
The final texture that gets rendered to preview ( and I think HMD ) seems to be offset in x by a small amount. This amount stays constant and is exactly half of the eye distance calculated by using the eyeToHead output.
Splitting the Previewoutput of the Composer Node in two textures and layering them on top of each other shows the offset and makes it possible to get a perfect match by texturetransforming one of the images.

As a temporary fix, I texturetransformed the images before composing them to the headset which seems to do the trick.

I found this while building a mono- and stereoscopic 360 Imageviewer, while creating spheres exactly around both eyes. The spheres can be scaled without any change to this offset which seems to indicate they are in the right place.

It would be great to hear from you. This might also be a bug but I don't know enough yet to suggest that.
Thank you ;)

new behaviour arrived - i start vvvv with vr running (vive) - everything works
if i will turn controller off and on while vvvv vr is running, it stops receiving all buttons from the controller, dashboard works, tracking works, i can ping the controller, but vvvv does not get buttons, only after i restart vvvv AND vr as well, can someone confirm?

Guys any Idea how to render volumetrics in VR?
Superphisical looks awesome, and also this other one volumetric-spot-light-(deferred)
but its a 2d texture added to the final render. how can I do that on VR?

Is it possible to make this track without HMD?
Imtrying to use only the tracker, but the poser showes no hmd error.

@tonfilm, one can setup the HTC driver to run on tracker only but the vvvv plugin insists on having the headset too. tried to grasp the plugin code to make a special case for "tracker only mode" but failed so far.

i could send you the tracker to berlin if you fancy...

@takuma, this is what i said in my last comment, there is no option like that in the plugin yet.

@tonfilm, i can send you a vive too :)

@catweasel @u7angle and @Takuma

i've checked the repo and found the place that requires some change:

OpenVRManager.cs Line 48

if you have a vive and someone with basic c# skills you can hack it. otherwise you have to wait until we have a vive setup here in the office and i have to time to dig into it.

@catweasel glad to hear that, you can place the repository directly in the vvvv/packs folder or use a symbolic link if you develop on it. hit me up in the vvvv chat if you need assistance.

@rogalog as soon as SteamVR works properly with it, it should work with this pack.

did i? i can't recall that... do you have a link? :)

@rogalag ah, i see what you mean. what i meant was that if you have it running with SteamVR and other games work with it, it should also run fine with the pack. but i have not tested it so far.

Hi, did anyone manage to track the new oculus touch sensor controller (Oculus Rift S)? The tracking of the controller position works fine, but i can't get any trigger/touch/press whatever signals. Does anyone have a tip?

Either way thanks for all your great work (this is my first post)!

is vive pro supported ?

Hello VVVVR community! I read that all devices working with SteamVR are also supposed to work in OpenVR but since I haven't read about it somewhere: Did someone already try the Vive Cosmos (and its differing controllers)? Thank you!
