Well, QCARControl.h (which is not part of the library) is included in EAGLView, and this contains thet dataset:

@interface QCARControl : NSObject {

@private

    // The current QCAR image tracker data set

    QCAR::DataSet* dataSet;

}

So, it should be easily accessible.

You could either make it public, or you could write an additional method on QCARControl.

Basically, I'm in EAGLView and I need to access the dataset (in the VideoPlayback example the number of targets is hardcoded in a macro and I would like to move it to a member variable).  How can I obtain a pointer to the dataset after loading the .xml?

The only problem is that it seems like the dataset is not exposed

er, not sure what the problem is?

The dataset is fully exposed, as you should be able to see from searching for it in XCode, as it is passed around as a parameter frequently.

There should be nothing stopping you from doing this:

        int numTrackables = dataSet->getNumTrackables();

Hi

I think the dataset (and the relative methods you're naming) should be accessible through the class QCARutils). The only problem is that it seems like the dataset is not exposed and I would prefer to not modify any class in ARCommon because this could compromise future updates. Any idea for a workaround?

You should be able to do this fairly easily by iterating through the dataset for each trackable, and then identifying each one by its name.

Look at Dataset.h which includes getNumTrackables() and getTrackable().

Also look at Trackable.h which includes getName().

It may also be easier if you drag the include/QCAR directory into the XCode navigator to make it more easily searchable.
