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!

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.
