Marker-Based Scene Alignment APIs (PC VR)
LBSS provides several application programming interfaces (APIs) to assist in
Marker-Based Scene Alignment.
Note:
This API can only be used with PC VR applications. For APIs designed for use with compatible AIO applications developed with the VIVE Wave VR SDK, see Marker-Based Scene Alignment APIs (AIO).
Configure marker ID and dictionary
Configures the marker ID and dictionary for one or two ArUco markers by retrieving the marker settings from the JSON file saved on your PC and sending them to the app or game you're using. Scene alignment only starts after users scan the secondary marker when configuring two markers.
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(" ", ""); // Spaces must be removed from the setting string.
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.
