Components

The scripts below can be attached to GameObjects for streaming data from QTM. They are built using the Qualisys Real-time Client SDK for .NET.

• RTSkeleton.cs - Add this script to use qtm skeleton data to drive mecanim humanoid character in Unity.
• RTMarker.cs - Add this script to a Game object to set the position of game object from a specific labeled marker name.
• RTUnlabeledMarker.cs - Add this script to a Game object to set the position of game object from a specific unlabeled marker id.
• RTMarkerStream.cs - Add this script to a Game object to visualize marker positions (using spheres) streamed from Qualisys Track Manager.
• RTBones.cs - Add this script to a Game object to visualize user defined bones (using line gizmos).
• RTObject.cs - Add this script to a Game object to get 6DOF object positions and rotations streamed from Qualisys Track Manager.
• RTObjectMarkers.cs - Add this script to Game objects of a 6DOF object body markers.
• RTGazeStream.cs - Add this script to visualize gaze vectors as lines.
• RTAnalog.cs - Example script to display how to get data from a specific analog channel (using name).
• RTAnalogIMU.cs - Add this script and set analog channel names for IMU data (X, Y, Z, W).
• RTForcePlate.cs - Add this script to visualizie force plate data. Example scene: DemoForceDataScene

Helpers

These are helper scripts used to communicate with QTM and add functionality to the Unity user interface.

• RTClient.cs - Main script that handles the communication between Qualisys Track Manager and Unity.
• RTGUI.cs - This script is responsible for handling the Window->Qualisys->RTClient option that shows the QTM Streaming window where the user can select which Qualisys Track Manager to connect to.
• RTGUIInGame.cs - This script can be used to show a QTM connection user interface when in Game mode.
