PPT User’s Manual

For situations in which you need to smooth your tracking data, the tracker's built-in
smooth method can be used. In the sample below, a mean filter is applied that
generates a running average across 4 samples.

CONNECTING TO 3RD PA RTY SOFTWARE
The recommended method of communicating with PPT is using the built-in VRPN 7
server, which is included as an output plugin by default.
Of all PPT output methods, VRPN 7 is preferred since it provides the lowest latencies
and highest bandwidth compared to all other available methods.
Interfacing with Vizard
If you are writing Vizard applications, then there is a separate page describing how
to use
PPT with Vizard .
Other Applications With VRPN Support
If your 3rd party application includes support for VRPN, then you should be able to
use this, since PPT provides a VRPN 6 and VRPN 7 output server as plugins. VRPN is
portable across many platforms, including Windows and Linux. Make sure the correct
server is enabled for your 3rd party application, and that Talk mode is enabled in the
PPT user interface.
Other Applications With MechDyne / VRCO TrackD Support
PPT includes a plugin for use with the MechDyne TrackD software. The plugins are
ppt-trackd.dll and pptwand-trackd.dll, and are located in C:\Program
Files\WorldViz\PPTStudio2010.
1. Copy ppt-trackd.dll and pptwand-trackd.dll from C:\Program
Files\WorldViz\PPTStudio2010, and put it into your trackd\bin directory (which
may reside on a different machine).
2. In the trackd configuration file, include the following lines for a standard PPT
tracking system:
