Hide / Unhide

April 23, 2012 - 8:46am #2

I'm using an ImageTracker and can successfully get my item to appear and disappear when finding my tracker.

Here's my question: I have an image I want to show when the tracker is not in view and then hide that image once the tracker is found. What is the best approach to do this?

Any suggestions would be appreciated. Thanks!

You could render this to the screen instead using an orthographic projection.

If you aren't familiar with OpenGL, you could instead use the Android SDK (or iOS SDK) to render the image to the screen. For Android, see this post for some help with changing the UI on tracking events:


You'll be interested in the case where state.getNumActiveTrackables() is zero.
