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.

Introduction to PPT Studio
The video tutorial in this article will guide you through the setup of a newly installed PPT system from the configuration of the camera settings to the streaming of tracking data. In order to follow along you should already have your cameras connected and positioned properly.

MotionBuilder actor using PPT
Autodesk MotionBuilder is a powerful character animation and motion editing tool. WorldViz Precision Position Tracker (PPT) can be used to stream data from a live actor into MotionBuilder. This video tutorial will teach you how to map the optical data being streamed by PPT onto a MotionBuilder actor.
Key-points covered in this video are:
- Loading PPT mocap plug-in
- Adding live marker data to scene
- Inserting & transforming an actor
- Previewing live actor within MotionBuilder
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
nVis SX / PPT setup
nVisSX is a high-quality stereo head-mounted display (HMD). PPT & Intersense are high-quality tracking devices that together provide a robust 6 degree-of-freedom solution. This post includes a video tutorial that guides you through each step needed to get your equipment running.
The key-points covered in this video are:
- Setting up PPT with a VRPN connection
- Connecting Intersense locally to the Vizard render PC by creating a merged position and orientation tracker
- Full sample script is provided below the video pane below
Emagin / PPT setup
Emagin is a low-cost stereo HMD. PPT & Intersense are high-quality tracking devices that together provide a robust 6 degree-of-freedom solution. This post includes a video tutorial that guides you through each step needed to get your equipment running.
