Trying to get the rift to work with C# for FreePIE

[CyberVillain]

Found this lib https://github.com/Entroper/VRapper

It uses the Hid device directly, I cant manage to get anything when I read.. I tried

Code: Select all

var trackerHid =
    HidDevices.Enumerate()
                .FirstOrDefault(
                    h => h.Attributes.VendorId == (int)SensorID.VendorID && h.Attributes.ProductId == (int)SensorID.ProductID);

var data = trackerHid.Read();

but it read blocks the thread and never returns.

Btw, are there any static C port of the lib? Could use that from c#

I've been thinking about doing this, but never got around to it. If you download the Oculus-enabled Unity SDK you can pull an Oculus interface DLL out of there and it should also contain C# import glue code as well which will make this task pretty simple.

There is a OculusPlugin.dll in there but it cant be loaded?

Found it, but it got dependencies to Unity, not something we want in FreePIE

Bummer. You should check the Oculus forums. I know there are some guys working on Java and C# linkages that might be helpful.

Will do thanks

You can take a look at: https://github.com/SiS-Shadowman/RiftDotNet

Checked it, but it had a lot of strange dependencies, will have a crack at the cpp code when I get the time. Compile a static C wrapper for it

The RiftDotNet code looks amazing and very complete, but I also didn't want the dependency toward SharpDx.
So I did a very barebone DLL and C# wrapper, just to extract the HMD orientation.

You can get the code (or contribute) at:
https://github.com/davyloots/riftsharp

I didn't include the actual LibOVR code project from the Oculus SDK because I'm not sure about the licensing, so you'll need to import that lib project before compiling.

If you just want to use it, here's a compiled version:
http://rcdeskpilot.com/system/files/RiftSharp.zip

The RiftSharpDll.dll is the C++ dll, RiftSharp.dll is the wrapper assembly. Just add a reference to that last one and copy the C++ dll to your binary folder.
Code use is as folows:

Code: Select all

using RiftSharp;

//.....
YawPitchRoll ypr = Hmd.Instance.YawPitchRoll;
float yaw=ypr.Yaw;

This is just a quick implementation, not even error handling is present. I'm not a very competent coder, so use at your own risk .

I missed this post so I created my own wrapper Nice work btw!

Brantlew, maybe this could be integrated into the SDK becasue it will make it work with most languanges under win32
