OptiTrack plug-in - stream unlabeled marker

[Jeff]

Does the marker have an index? If so, you could try the motive.getMarker(val) command and use the index value.

Hi Jeff,

we use the following code to try to get coordinates of the marker positions:

import viz
viz.go()

optitrack = viz.add('optitrack.dle')
motive = optitrack.addMotive('127.0.0.1')
	
print motive.getMarkerList()
marker =  motive.getMarker(0)
print marker.getPosition()

The code returns the following text:
************************************************** ****************************
** Loading optitrack.py
************************************************** ****************************
optitrack.dle OptiTrack Extension
** OptiTrack: [Client] Initializing using ethernet address: 127.0.0.1

[0.0, 0.0, 0.0]
** Load Time: 0.24 seconds



So, we have the two problems:
1) The position is always [0.0,0.0,0.0]
2) Markers not belonging to a rigid body do not appear in the MarkerList

Could you help us with that?
