Trackable location problem

Post by totti0820 » Sun May 13, 2012 7:55 pm


I am trying to create a trackable rigid body and then track the location of it using the tracking tool API. However, I found there is a problem, no matter where I put the markers, after I successfully create the trackable with TT_CreateTrackable(), the TT_TrackableLocation() always return me a location (0,0,0) and orientation (0,0,0). Later I tried to track some simple movement, it seems correct, for example, I move the rigid body 0.5m along Z direction from the initial place, TT_TrackableLocation() would give me a location (0,0,0.5), though the absolute location is not correct.

Did anyone else come across similar problems? and could anyone help?

BTW, I m using V120 Trio....

Thank you very much

Has your ground plane been set at the time the trackable is created?
