OpenVR-SpaceCalibrator

Use VR devices from one company with any other.

This is beta software and may not work for you. A quick video walkthrough of the calibration process is available at https://www.youtube.com/watch?v=W3TnQd9JMl4

Usage

Calibration

If you don't already run a setup with multiple device types, see Setting up SteamVR.

1. Download and unzip the latest release of OpenVR-SpaceCalibrator.
2. Run SteamVR, and turn on your Touch controllers and only one Vive device to use for calibration.
3. Run OpenVR-SpaceCalibrator.
4. Hold the left Touch controller and your Vive device in your left hand securely, like they're glued together.
5. Click "Start Calibration"
6. Wave your left hand around, like you're calibrating the compass on your phone. You want to get as many orientations as possible.
7. Done! A profile will be saved automatically. You can turn on the rest of your Vive devices now.

Next time you run SteamVR, open OpenVR-SpaceCalibrator and it will load the calibration automatically and apply it devices you turn on.

Setting up SteamVR

Every hardware designer with their own tracking system needs to make a "driver" so SteamVR can see their tracking data. SteamVR by default will load only one driver at a time, but we can tell it to load all of them by editing the vrsettings config file.

Open Steam\steamapps\common\SteamVR\resources\settings\default.vrsettings in a text editor, look for the line that has "activateMultipleDrivers": false and change the false to true. In some guides online you may also see references to requireHmd, this does not need to be changed unless you truly want to be able to run without any kind of HMD.

Sometimes when SteamVR updates this file seems to get wiped, if your setup stops working you might have to edit the config again.

Compiling your own build

1. Open OpenVR-SpaceCalibrator.sln in Visual Studio 2015 and build.
