Phase Space and Vizard
Hello everyone -
I am a student at the University of Minnesota and I am working with Vizard and a PhaseSpace tracking system. I am unclear on how to set up a 6DOF from the PhaseSpace markers from the Vizard documentation. I am just trying to make link the Vizard Main View to a object that PhaseSpace is tracking so we are then able to use a HMD. I know about the PhaseSpace plug-in for VIzard: http://docs.worldviz.com/vizard/PhaseSpace.htm Also I am not able to find any information on how to "fuse" two 3DOF trackers to make a 6DOF. I have found the viztracker.py documentation. All the help is greatly appreciated. |

Take a look at the viz.mergeLinkable command. That will allow you to create a single 6DOF tracker from two 3DOF trackers.

Thanks for the information. I think that is a step in the right direction for what I am trying to get. But do you know anything about the PhaseSpace command <phasespace>.addMarker() because I am a little unclear how I know which marker I am going to get when I call the function.
Thanks again for all the help. |

To revisit this...
Mergelinkable takes the orientation from one sensor/object and the position from another sensor/object. This isn't the case with PhaseSpace - we just have position information. It still feels like this should all be quite easy in Vizard, but there doesn't seem to be a nice walkthrough. With three position sensors, we should be able to define a rigid body, which then has position and orientation information. Thanks! -Matt |

Are you able to define rigid bodies in the PhaseSpace software? If so, does it support streaming that data via VRPN?

I believe so, but we've someone looking into it. There's a API for Python that we're reading up on.
But initially it sounded like there was an easy way to link up the position sensors within Vizard, forming a 6DOF sensor from several 3DOF sensors (as the OP was asking)... but digging deeper, all the examples are for combining position info with orientation info. |
