PPT and Intersense Alignment
A typical setup for PPT users is to connect an Intersense to the Vizard rendering machine for orientation data and combine that with position data streaming from the PPT machine. Having the Intersense connected to the Vizard rendering machine is recommended when the data is applied to the viewpoint, as it will give the lowest orientation latency possible. Using this setup, it is necessary to perform the alignment between Intersense's coordinate system and PPT's coordinate system in the Vizard script. This article describes several ways of doing this.

PPT mocap plug-in
Learn how to use the mocap plug-in to stream data from WorldViz Precision Position Tracker (PPT) to Autodesk MotionBuilder. With this workflow, you can capture an actor's full body motion with just 5 or 6 PPT markers. MotionBuilder is used to apply inverse-kinematics (reconstructing the missing joint data). The results of MotionBuilder can then be streamed again to Vizard for use with Live Characters or for recording to file to later replaying animations.
The key-points covered in this video are:
- Correctly configuring PPT & plug-in mocap use
- Combining Intersense cubes for higher quality mocap
- Adding MotionBuilder output plug-in
- Correctly reseting T-pose
