[IGSTK-Users] tracking in IGSTK 3

["Özgür Güler"]

Hello,

I've written an igstk app with release 2. It works well.
Now I'll port this app to igstk release 3.
I'm using a PolarisTracker (1.Generation (driver written by me)) with a referenceTool. Tracking works well.
In detail I've problems to set correctly the 
->RequestSetTransformAndParent(..,..)
functions for the Objects Tracker, TrackerTool, ReferenceTool, ImageSpatialObject.



I tried many constellations e.g. one of them
...
m_ImageSpatialObject->RequestSetTransformAndParent(transform, worldReference);
...
//tracker init: transform = identity
referenceTool->RequestSetTransformAndParent(transform, worldReference);
...
//landmark registration: transform = computed from registration
referenceTool->RequestSetTransformAndParent(transform, worldReference);
...
//Tracking
trackerTool->RequestComputeTransformTo( worldReference ); 

this constellation didn't work.
Is there an error in my reasoning? 
How should I set up the associations between the transforms and the object parents?

please help.

best regards
