Hi,
Apologies if this is answered elsewhere, but we couldn't find the answer!
We have an application that is using Vuforia to (Mode A) capture images from the devices camera and we build a DataSet of trackables which are then (Mode B) matched to invoke other elements of the application. This is all offline - we're not using (and cannot use) Target Manager or the Cloud.
It works very well, apart form the fact that each time the app is restarted, we have to rebuild the DataSet from scratch - so we need to persist the DataSet.
I can see that DataSet has a load() method, but there's no corresponding save(). Are we approaching this in the wrong way or is this a limitation of Vuforia (which would appear to be a considerable oversight).
Hope someone can help - we've already invested a lot of time into Vuforia, so it'd be a shame to have to go back to the drawing board for feature capture/matching.
Hello
It is a shame that Vuforia approaches it like this. I have been evaluating Vuforia for a few days but with this kind of limitations popping everywhere I will have to pass into something else.
