Setting up Marker-Based Scene Alignment
Marker-Based Scene Alignment allows you to align virtual scenes with physical environments by using ArUco markers.
- Set up the headsets you'll use in the play area. See Setting up the headsets.
Decide where you want to put the marker, and then measure the distance from the floor to the center of the marker's intended position. For the best performance, place the marker near the edge of a wall or on a pillar. You can also place it on the floor.
Note: Marker-Based Scene Alignment supports up to two ArUco markers. Using two markers improves the precision of scene alignment, but any difference between the position of the markers in your play area and their position in the virtual scene may affect alignment results.
- Align the position of the marker in your virtual scene according to the intended position of the marker in the play area. See Configuring the position of an ArUco marker in a virtual scene (Unity).
- Create your ArUco marker. See Creating ArUco markers for Marker-Based Scene Alignment.
- Place the marker in your play area as planned.
- Create your tracking map. See Creating a map with VIVE Manager.
- Import the JSON file generated when you created you markers into the tracking map, and then save the map.
- Move to the play area and put on your headset. The headset should wake from standby mode.
Scan one of the
ArUco markers with your headset. The virtual scene will align with your play area.
Use the Retain alignment API to keep alignment results intact if you change environmental settings or switch VR apps:
key = "ClearRecenterXform"; Interop.WVR_SetParameters(WVR_DeviceType.WVR_DeviceType_HMD, Marshal.StringToHGlobalAnsi(key));Note: This API will affect any tracking devices or other accessories connected to the headset.
