[IGSTK-Users] optotrak igstkNDICertusTrackerTest GetTransform problem

Wed Feb 6 06:03:28 EST 2013

Hi Özgür,

I used this function RequestSetFrequency() in "igstkNDICertusTracker", "igstkTracker" and also in "igstNDICertusTrackerTest". But the result has unfortunately not changed. I get still no valid transformation and positions. 

I send you my current logger. If I am right there, there is no state with faulire in statemachine.

Thank you for your help.

Mit freundlichen Grüßen
Yusuf ÖZBEK

Hi Yusuf,
just use following function in your tracker class and set it e.g. to 10:
RequestSetFrequency( double frequencyInHz );

Let me know if this helps,
Ozgur
