[IGSTK-Users] tracking in IGSTK 3

[Andinet Enquobahrie]

Hi Ozguar,

To help you troubleshoot the problem, can you give us high level 
description
of your application? You can use the following questions as guidelines

1) What components do you have in your application? (How many tracker 
tools,
     View, Image spatial object...etc)

2) How are they connected?  ( a sketch of collaboration diagram between 
the components would
 be great .)

3) What is the work flow of your application?

If you provide us with the above information, we will be able to 
effectively help you
diagnose the problem.

Thanks,
-Andinet
