Unity and VRPN integration ?

[Totti Anh Nguyen]

Hello VR Geeks,

Has anyone implemented the integration between Unity 3D and VRPN ?

Unity is now a popular game engine, but unfortunately, its support for optical tracking (like OptiTrack) or other VR devices like gloves.. is not seamless at the moment.

Not sure if anyone has experienced with such an integration.

Your sharing would be very much appreciated !

Thanks

In our lab, we use VRPNWrapper https://research.cc.gatech.edu/uart/content/vrpnwrapper

It works well for our needs. Hope it suits yours.

Good luck!

Marwan

Hi Marwan,

I have a question please.
I Build the project and i have many error (Library do not exist: smft31.lib, smftcpp.lib, pthreadVC2.lib, SharedMem.lib).

Did i miss anything please?
Thank's.

[Marwan Badawi]

Weird, never had this error. Are you building with Unity Pro?

Yes, i use a Unity Pro.
Out put :
DllNotFoundException: C:/......../uart-code-51-trunk/uart-code-51-trunk/Projects/VRPNWrapper/Assets/Plugins/VRPNWrapper/VRPNWrapper.dll
VRPNManager.Start () (at Assets/Plugins/VRPNWrapper/VRPNManager.cs:145)

[Ben Chang]

We also got a DllNotFoundException.  Until we get it figured out, we're doing it in a slightly roundabout way.  We had some code in Panda3D already set up to use VRPN with Vicon Tracker, so we just took that and forwarded the data on to Unity using OSC.

[Marwan Badawi]

Sorry it took so long to reply, I've been away for a while.

It's been a long time since we nitegrated this and I don't recall any problems. Looking at our project's directory structure, I notice that we don't have a VRPNWrapper subfolder in our Plugins folder. The VRPNWrapper.dll and all the .cs files are directly stored in the Assets/Plugins folder. Maybe it will help if you do this?

Don't forget to change the DllImport directives from [DllImport ("VRPNWrapper/VRPNWrapper")] to [DllImport ("VRPNWrapper")].

Hope it helps,

Marwan

Thank you very match Marwan, I'll test it :)

thx

Hi,

I tried moving VRPNWrapper.dll and the .cs files into Assets/Plugins and updating the DLLImport directive, but I still get the "DLL not found" error. 

What's odd is that the error says "DLL not found" and gives the exact correct path of the DLL.  I'm wondering if the problem is a secondary dependency?  Maybe VRPNWrapper.dll is trying to link to something else which is not being found, and that's what throws the error.  I tried looking at it with a DLL dependency walker tool but don't understand Windows linking well enough to know what to do with its output.

[Marwan Badawi]

Maybe try to build the dll yourself then? The link to the source SVN are on the VRPNWrapper website.

Good luck and sorry I can't help more than that.

Hi, I am sorry for asking here too late. As its an old post. But I am trying to Integrate Vicon Tracker 2.0 with Unity3D. And I found this thread. So, can you please tell me if there  is any documentation for your VPRNWrapper available and is it possible to get data of Vicon Tracker through this wrapper? 

[asema....@gmail.com]

Hi Koorosh,

I have checked out your post this:  https://sourceforge.net/p/vrpnwrapper/discussion/1087054/thread/020a5275/  how to configure VPRN wrapper with Windows. Do you have any idea about how to do that in MAC OSX as well? As I have having the same issue vprnwrapper.dll not found.

You realize you are replying to a 2 years old post, right? It is
probably better to start a new topic in such case.

Re VRPN and Unity - calling VRPN libraries from C# is not that
difficult, but today I would rather recommend you to use the
maintained OSVR bindings for Unity. OSVR can act as a bridge for an
external VRPN server (e.g. your Vicon).

Jan

Hi my thesis is in a VR project with VRPN Server and VRPNWrapper as well. Everything works fine in Unity5.3 64bit and Unity 4.6 32bit, if you are still interesting in this send me a message.
