VL.Devices.Nuitrack

Probably too late for this request but the time to add Nuitrack support to VL has come!

We are opening the discussion to anyone interested to share their use cases, needs, ideas and experiences with this tracking API in order to make the most of the upcoming nodeset.

Even though we are still pretty much on the research stage, the main intention is to make the nodeset as similar as possible to VL.Devices.Kinect2 which is still WIP but has already laid the groundwork for Skeleton tracking.

We see there’s already been an attempt here, hope to get some input on experience by @neuston.

Please do join the discussion and bring any thoughts you have on the subject to the table.

To test the current progress just download and install the nuget package as explained here.

The command should be:

nuget install VL.Devices.Nuitrack -prerelease

Also for the brave hearted, we have a github repo at https://github.com/vvvv/VL.Devices.NuiTrack.

Cheers and happy patching!

Hey @ravazquez,

Stoked to hear you’re on it!
Still quite surprised it’s not appealing to more people out here.
We’ll be happy to beta test, we have a bunch of Intel / Orbbec / Kinects here to check out performance across hardware.

Probably too late indeed for our upcoming project but we’ll be looking forward to try this out!
(if dev is coming out pretty easy/fast, do hit me up though!!)

One first suggestion: I have been looking into the OFx.nuitrack addon’s .h real quick, and I think the face tracking has not been wrapped (should be easy to add, but still a bummer it’s not included in the contribution by default imho).
The feature is turned off by default in nuitrack’s config file, and it has to be polled separately and returns a JSON string. Face info is hidden under “User Instances” in the API docs, a bit hard to find at first, here is the link.
And here a blog post they made on the subject.
I think it would be great to have this supported to not look back to Kinects and Kinect nodes just for face tracking needs ;)
What do you think?

Best

Never had a chance to use Nuitrack, but we also have a bunch of Kinects and RealSense here, would be happy to help with some testing :)

It is such a great news! But I have stopped trying Nuitrack+VL since my last post. Thus, I cannot input more. Instead, I integrate Nuitrack in vvvv by traditional c# plugin. Normally, it works (but its license checking process will block the opening of new patch windows )

First draft nuget with RGB and Depth Reactive nodes + simple Overview help patch now available! Check first post or github page for more instructions but in summary:

nuget install VL.Devices.Nuitrack -prerelease

Hi ravaquez

tried it with:
Orbbec Astra Model:Astra
Microsoft Kinect v2
vvvv gamma 2019.1 preview 411

Overview.vl is loading and I see VL.renderwindows and VL.nodes appearing - then sudden death with Orbbec Astra, with Kinect I even see something in the renderwindows but frozen and then also sudden death - no error message appears

how can I have a look at a kind of a logFile so I can maybe tell more

Greetings
Daniel

Hi @CeeYaa, I updated the installation instructions yesterday, please make sure you follow all the steps here: https://github.com/vvvv/VL.Devices.NuiTrack/blob/master/README.md

Basically your Nuitrack SDK install should be working before you attempt to use the VL nuget.

If you can see data coming in from the steps in section “Activate Nuitrack” then VL should also work.

Please report back with your findings.

Cheers.

Hi @ravazquez

Stupid me - NuitrackSDK not activated - NuiTrackTrial license is linked to one PC, after I got a new key - NuitrackSDK works and also you VLpatche Out Of the Box - as usual, looks good - after 3minutes quit but this is the TRIAL - now I have some testtime, if I should go for a PRO

THX again ravazquez
Great contribution

Glad to hear you got it working, and remember it is still very much WIP.

As of version 0.1.6-alpha Skeleton tracking nodes have been added.

Please test and report.
