Running Marker-Based Scene Alignment with VIVE Business Streaming

Run Marker-Based Scene Alignment with VIVE Business Streaming for setups that use PC VR headsets.

Set up the headsets you'll use in the play area. See Setting up the headsets.
Set up Marker-Based Scene Alignment. See Setting up Marker-Based Scene Alignment.
On your PC, open VIVE Business Streaming, then go to Advanced > Program and turn on Beta.
Connect your headset to your computer using a USB Type-C cable.
In VIVE Business Streaming on your PC, go to About and click Install to update VIVE Business Streaming on your headset.
Open SteamVR and start streaming your desired app or game.

Call the following API. This API tells the app or game you're streaming which ArUco markers you're using.

string key = "‍ GetParameters PLAYER00InitMA"‍;
// default path: C:\Users\{USERNAME}\Data\markers_list.json
string filePath = Environment.ExpandEnvironmentVariables(@"‍%USERPROFILE%\Data\markers_list.json"‍); 
string setting = File.ReadAllText(filePath);
setting = setting.Replace("‍\n"‍, "‍"‍).Replace("‍ "‍, "‍"‍); // setting string must remove space
key += setting;
uint RETURN_SIZE = 256;
StringBuilder value = new StringBuilder("‍"‍, Convert.ToInt32(RETURN_SIZE));
OpenVR.Debug.DriverDebugRequest((uint)DeviceType.HMD, key, value, RETURN_SIZE);
string result = value.ToString();
if (string.Compare(result, "‍InitMAErr"‍) == 0)
{
   // write your error handling code here
}

Note: Make sure to insert the correct file path for the JSON file associated with your ArUco markers.

Note:

Scene alignment is not affected by SteamVR activity, including switching games or apps, closing a game or app and returning to SteamVR home, or restarting SteamVR.
