[IGSTK-Users] Polaris reference tool

[Ziv Yaniv]

Dear Jason YEE,

To set a tool as a dynamic reference you first initialize the tool as
you would with all tools then attach it to the tracker and finally set
it as a dynamic reference.

pseudo code:

Tracker;
Tool;

Create and initialize tracker;
Create and initialize Tool;

Tool->RequestAttachToTracker(Tracker);
Tracker->RequestSetReferenceTool(Tool);


Once you start tracking the reported transformation will be relative to
the reference frame.


If you are looking for generic code that works with all IGSTK supported
trackers please take a look at the TrackerController class and the
tracker configuration and xml file readers. These allow you to specify
the tool configuration in an xml file and you don't have to write the
initialization and setup code as described above. A good example of
using this framework is the Navigator application.

               regards
                    Ziv
