You'll add the datasets to your assets folder and then you can switch between them using a update callback class - see ImageTargets_UpdateCallback on line 90 of ImageTargets.cpp in the ImageTargets sample project for an example of how to do this. This class is called when the tracker is updated and capable of loading and de/activating datasets.

I'm sorry that I didn't declare that i'm trying to do that on Android... and i tried to find something in the fourm even searching here in the fourm is some kind confusing, but didn't find what i'm looking for...thanks in advance.

This is straightforward.

Assuming you are using iOS, simply add the dataset .dat and .xml files to your resources.

Then at runtime you can use ActivateDataSet to select the dataset that will be used.  Only one dataset can be active at any time.

It might be worth searching the forums to see if this question has been answered before.

I'm sorry but I'm new here, so can you tell me how exactly can I use more than two datasets?

Thanks for information ;)

Hi GabrielS

You can have any number of datasets, but only one can be active at any point in time (using activateDataSet)

In each dataset there is a mentioned figure of 80 images per dataset, though some have had success in loading many more than this.
