Dynamic Trackables

By justbcuz on Wed, 06/20/2012 - 17:05
Is there a way to load Trackables dynamically? Can I specify the location of the config.xml and the qcar-resources.dat files?

Currently the trackable files must be present in the assets folder at compile time and cannot be changed at runtime. We are considering dynamic loading of trackable files for future versions of the SDK. - Kim

Hi, How about overwriting the trackable file with a new image? For example, having a limited number of trackables in the application (say 5), and once you need a sixth, you just overwrite the oldest one with the new one, keeping the name of the file. Would that work?

No, sorry, the tracking data is embedded in the application and can't be swapped out. - Kim

Oh okay... Thank you for the info. I guess we'll have to figure something else then. :)

[QUOTE=ksiva]Currently the trackable files must be present in the assets folder at compile time and cannot be changed at runtime.

I was just messing around with the sdk, and tell me if I'm wrong, but on iOS just by moving a qcar-resources.dat and the config.xml file from the application bundle directory to the application documents or library directory would make them half-easier to update.

From what I understand Kim said, is that the .dat and .xml files are compiled into the application when Xcode or eclipse builds the application.

Well, to be completely honest, I didn't actually try the Android version, but I messed around in the file system of the iPhone after installing my application, and the config.xml and resources dat files are in the main bundle folder location.

Sorry for bringing this thread up again, but is there any progress on this? I know it's on the roadmap, but how far away is it on the map? :)

The Vuforia Web Service will enable Trackable Datasets to be generated and retrieved programmatically. This service is currently in private beta and the public introduction of services has not yet been announced.

This is irrelevant to the post but could u please help me out in building a sample app which opens a UIView when image is detected. I have referred to all the posts related to this but unable to make anything working.

Hi junkieHead,

My suggestion is to get familiar with all the samples first in order to understand the workflow - unfortunately there is no shortcut ;)

Dear NalinS,

Thanx for your reply. I will surely try the UIView popup thing.
